WO1994021913A1 – Oscillating Converter Driven By A Fluid Flow – Google Patents

arturo goicoechea: Dolor y necrosis / Pain and necrosis According to Fig.2 the outer casing 26 has a slot-like orifice 42 on an underside through which the pivot shaft 14 of the body 12, fixed to the movable trolley 20, ex- tends downwards, in other words in the direction towards the surface of the water. The position of the pivot shaft 14 in longitudinal direc¬ tion of the body 12 and non-illustrated stops on the pi¬ vot shaft 14 are matched to each other, such that the body 12 between the banks cannot be rotated by the flow into a position parallel to the direction F of flow, so that a component of force, caused by the flow, is con¬ stantly present, through the means of which the body 12 is moved transverse to the direction F of flow towards the right in Fig.l.

The com¬ ponents of force at right angles to the direction F of flow, acting on the body 12, are transmitted via the pi¬ vot shaft 14 to the movable trolley and ensure that this trolley moves towards the right. The movable trolley 20, therefore, moves with the body 12 towards the right-hand bank of the water in Fig.l. The converter system according to the invention, therefore, is scarcely subjected to ac- celeration or braking at any time. According to the invention, the displaceable body, dis¬ placeable by the flow in a back-and-forth motion, is no longer coupled by means of a pivotal or rotary bearing, but by a movable vehicle. Fig.l is plan view of a part of a flow engine compri sing the converter system in accordance with the invention, Fig.2 is a sectional view according to the line II-II in Fig.1 and Fig.3 is a sectional view of the converter system ac cording to the line III-III in Fig.2 and comprising the vehicle and the primary linear guide.

If the converter system is used in a mechanism for utili¬ sing hydro-mechanical energy, in other words, in a stream of flowing water for example, it is essential that the body struck by the flow is always completely immersed in the water and is able to be matched to the level of the water. The converter system in this embodiment is very compact yet stable, and in particular is able to be al¬ most completely preassembled. Someti- mes, even the linear guides themselves are not completely straight and true, so that where there are small inaccu¬ racies in the straightness, transverse forces can act upon the primary linear guide. Even for this further converter system of prior art, the compo¬ nents to be moved must be frequently subjected to accele¬ ration and braking action.

The inertia of the entire components in the said converter system being constantly subjected to acceleration and braking thus leads to unne¬ cessary waste of energy. The efficiency of this known converter system is poor, since constant acceleration and braking action of the converter system occurs, due to the reciprocal motion of the frame. The frame itself is coupled for its part to the known conver¬ ter system, which is designed as a weight or a spring pull mechanism. The mo¬ vable trolley 20 has four rollers 22 and 23, respecti¬ vely, each at both of its ends, which run on four tubes 24, which extend almost at right angles to the direction F of flow over the flowing water from one bank to the op¬ posite bank. A piston 52 is disposed radially inside the cylinder 40. The piston has a rod 54, which is arranged coaxially to the cylinder 40, and on each of both end faces of the rod a cover plate 56 is attached with a radial gasket 58 arranged therein.

The movable trolley 20 forms a slidable supporting device for the vehicle itself, in order to keep all forces away from the vehicle 30 and the cylinder 40. Dolor en el dedo corazon de la mano derecha . If the cylinder 40 is designed sufficiently large enough or the vehicle 30 is movable on several parallel acting cylinders 40, the secondary linear guide 25 with the movable trolley 20 as a supporting device can be dispensed with. The arrangement shown in Fig.3 thus forms the converter system 10 for the flow engine and converts movement of the body 12 produced by flow into usable en¬ ergy, in this case compressed air. A vertical arrangement of the retaining mechanism as in DE patent 6 84 417 would also be feasible, in which the vehicle would then move vertically. An accurate, parallel aligned arrangement of the primary linear guide relative to the secondary linear guide is particularly problematic with long linear guides.

It is advantageous where there are high transverse forces acting on the primary linear guide in accordance with the embodiment of the invention according to claim 9 to pro¬ vide a secondary linear guide arranged parallel thereto, in order to then absorb all transverse forces by the se- condary linear guide, which should then be of more sturdy design. All forces in the direction F of flow acting on the body 12 are transmitted via the pivot shaft 14 and transmitted on via the movable trolley 20 to the secondary linear guide 25 and thereby absorbed. The body 12 has an airfoil form and is attached by a pivot shaft 14 to a movable trolley 20. The movable trolley 20, which, in simplified form, is depicted in Fig.l by rol¬ lers 22 and 23 and by axle-like connecting parts 33, is slightly movable in the direction F of flow, but fixed transversely to the direction of flow connected by pins 28 to a vehicle 30 arranged centrically therein.

In Fig.l is depicted a part of a flow engine having a body 12, which is arranged at an angle in relation to a direction F of flow in a stream of flowing water. According to Fig.l the flowing water flows towards the body 12 standing at an angle to the direction F of flow. The body 12 thus pivots to an opposed, mirrored position to that illustrated in Fig.l. The retaining mechanism and the body connected to it are thus at a constant optimal position to the flow, which can, for example, be a flow of air or water. The bridge also has a polygon cross section, to the corners of which wheels of the moving trolley are guided and sup¬ ported. Seen in cross section the movable trolley 20 has a clover leaf- like form. The retaining mecha¬ nism can also be of round bar material as a guide, on which a sliding bush is movable as the vehicle.

The casing 36 of the vehicle 30 has a large internal bore 38, in which a plurality of an¬ nular magnets 46 are axially arranged side by side and pressed one against the other. Because the cylinder 40 is relatively long, a relatively large amount of air can be compressed per stroke of the piston 52. The time in which the converter system 10, the body 12 and the movable trolley 20 accelerate and decele¬ rate is very small in relationship to the total travel¬ ling time from one bank to the other. However, if this linear guide features the embodiment of the invention according to claim 10, in other words is slidable, or is connected, as in the embodiment of the invention according to claim 11, by a flexible connecting flange to the secondary li¬ near guide the primary linear guide can avoid the occur¬ rence of transverse forces.

In accordance with the embodiment of the invention according to claim 14 the supporting device is additionally designed to yield fle¬ xibly in the direction of flow. On the right-hand bank a spoiler flap 68, arranged in the body 12, is then activated by a non-illustrated control device, causing a pivoting of the body 12 in counter-clockwise direction. In the embodiment of the invention according to claim 2 the retaining mechanism is arranged horizontally approxi¬ mately at right angles to the direction of flow or can be adjusted horizontally approximately at right angles the¬ reto. In the embodiment of the invention according to claim 4 the converter system comprises at least one unit consi- sting of a cylinder and a piston, which form the linear guide or the vehicle, respectively, or are a part the¬ reof.

This additional converter system is part of an arrange- ment for utilising hydro-mechanical energy and comprises a piston cylinder unit, which is operable by a rotatable flap fixed to a retaining mechanism. The flow engine comprises a blade which is exposed to the flow of a medium and is ro- tatably attached to a thereby displaceable body in the form of a frame, displaceable in a reciprocal motion. The vehicle could also be a movable beam, which is located between stationary rollers and causes these to rotate.

By pushing the piston 52 in Fig.3 towards the right, the piston draws additional air into a left-hand cylinder chamber 64. The body 12, the movable trolley 20, the vehicle 30 and the piston 52 move in unison up to a non-illustrated stop on the right-hand bank. Isquiotibiales cortos dolor lumbar . If the piston 52 in Fig.3 is pushed to the right, for ex- ample, then air, which is present in a right-hand cylin¬ der chamber 62, is compressed by the piston 52, and the compressed air so produced can flow via a line 66 to a service unit. The cylinder can be a hydraulic or pneumatic cylin¬ der, wherein a pneumatic cylinder has certain advantages, due to the modest inert mass of the air to be displaced. The piston and the cylinder are, in this embodiment, components of the retaining mechanism. In the embodiment of the invention according to claim 3 the retaining mechanism is a primary linear guide for the vehicle.

In the embodiment of the invention according to claim 18 the secondary linear guide is designed as a bridge, and can therefore be very simply and quickly installed. The linear guide can thus, for example, simply comprise a beam having a longitudinal groove, in which a groove nut is arranged as a vehicle. As a result the body travels in unison with the vehicle, due to the flow, and covers a substantially longer distance for half a cycle, i.e. Dolor en todas las articulaciones del cuerpo causas . The converter system 10 can be fully preassembled and also serve as a bridge, as Fig.3 shows. Such a converter system is described in DE patent 6 84 417 as part of a flow engine.
