Limit mechanism 62 may be adjusted to control the angle of confrontation of vane 16. To initiate the stroking motion of swing arm 18, limit mechanism 62 is adjusted to allow a steeper angle of confrontation. Alternatively, a rotational stop could be installed behind horizontal support member 22 or over swing arm 18 to limit the vertical motion of swing arm 18. As an alternative to, or in combination with, these mechanical stop mechanisms, vane 16 could be weighted or buoyancy added according to the anticipated flow conditions, in conjunction with the overall hydrodynamic design of the vane, to maintain vane 16 at the desired level. Referring to FIG. 1, power system 10 includes an oscillating fluid flow motor 12 and an on-shore receiving machine 14. Receiving machine 14 represents generally any of the various machines operable through the reciprocating motion generated by motor 12, such as a pump, electric generator, mill or compressor.

The adjustability of limit mechanism 62 may also be used to improve operating efficiency under variable workloads of receiving machine 14 and varying currents and other conditions affecting the fluid flow. 2, flexible joint 51 incorporates a universal joint 52 and a cross link ring 53. A ball joint or any other suitable joint allowing a free range of motion, preferably allowing link 38 and swing arm 18 to pivot relative to one another about at least two axes, could also be used.

The fluid balancing network 160 opens a secondary pathway to the input annulus chamber through a flow restrictor and one-way valve with very small diameter hydraulic connection. Referring to FIG. 9, a power dissipation network 170 is shown connected to an isolated hydraulic system. Referring to FIG. Dolor en todas las articulaciones tendones cuello y dolores cervicales . 9, the secondary angle of attachment σ of swing arm 18 to vane 16 is preferably in the range of 45° to 135°, most preferably about 90°, where σ is the angle between swing arm 18 and a transverse chord 44 of vane 16. Other configurations for vane 16 are possible. 1, where θ is the angle between swing arm 18 and a longitudinal chord 42 of vane 16. Primary angle of attachment θ is selected to achieve the desired angle of attack Φ or “bite” of vane 16 in the fluid flow (attack angle Φ is shown in FIG. In one embodiment of the oscillating fluid flow motor, the motor includes (1) a support structure, (2) an elongated swing arm pivotably and rotatably mounted to the support structure, (3) a vane having a concave face, (4) an elastic link operatively coupled in tension between the swing arm and a support, and (5) a direction control mechanism operatively coupled to the swing arm.

Dolor en la espalda alta: 9 causas The embodiment depicted in FIGS. 10. The hydraulic energy that may be extracted from fluid passing over vane 16 depends on several factors, including the length of the vane, the shape of the vane and the depth and velocity of the flow. As the transfer of hydraulic fluid is slow, the system adjusts over many cycles and is able to otherwise function as normal. 1 is an isometric view of an oscillating fluid flow motor incorporated into an in-stream fluid power system wherein the swing arm extends away from the vane in a direction generally upstream of the vane. Generally speaking, mechanisms for converting the energy of a moving fluid to mechanical power have tended throughout their evolution to become both more complicated and more costly to manufacture.

BACKGROUND OF THE INVENTION Numerous mechanisms have been designed and built for converting the energy of moving masses, such as air or water, to mechanical energy. A relatively short stroke midstream in the fastest portion of the fluid flow, for example, appears to increase power output. For example, swing arm 18 may incorporate a rotational motor and electronic monitor. As the electronic monitor senses that swing arm 18 has reached either the predetermined first or second outer limit of travel, the electronic monitor causes rotational motor to rotate swing arm 18 about its longitudinal axis. Vane 16 traverses back across the flow until swing arm reaches a second outer limit of travel, and direction control mechanism 20 causes the swing arm to rotate in a second opposite direction about its longitudinal axis inside pivot assembly 24 again reversing the direction of vane 16 across the flow.

FIG. 5 is an isometric detail view of a second embodiment of a direction control mechanism utilizing magnetic repulsion. In one particular embodiment as depicted in FIGS. In one embodiment of the invented fluid flow power system, the system includes (1) a channel, (2) fluid flowing through the channel, (3) an elongated swing arm pivotably mounted in or over the channel, (4) a vane connected to the swing arm, the vane having a concave face confronting the flowing fluid, (5) a direction control mechanism coupled to the vane, and (5) a receiving machine operatively coupled to the swing arm. As the workload of receiving machine 14 is met, the angle of confrontation is made less steep to improve operating efficiencies.

A connecting rod transmits the energy in the oscillating tiller to some type of receiving machine to produce useful work. Experimentation has also shown the fluid deflecting off vane 16 scours the bed of the channel. FIG. 6 is a partial isometric view of a vane and swing arm showing the change in direction at the end of one stroke of the swing arm. Infección de orina y dolor lumbar . The direction control mechanism is operative to selectively re-orient the face of the vane at each of two points that define the ends of the bi-directional stroke of the swing arm.

FIG. 10 is a detail isometric view of a vane having a front face that is concave only along its transverse axis and a rectilinear peripheral edge. Ideally, the fluid should enter vane 16 nearly parallel to the leading edge and exit nearly parallel to the trailing edge. The energy stored in the pressurized fluid can then be used to apply a mechanical load to an electrical generator. Conversely, if the flow is fast, then a smaller deflection will cause cavitation. Pat. No. 5,889,664. The improvements result from further testing and study of the motor’s basic design. The strength of the magnets depends upon the size of vane 16, the length of swing arm 18 and the force of the fluid flow. In some embodiments, the offset cylinders 130 are coupled to a gas charged accumulator. Generally, the offset cylinders 130 offset the weight of the tether 106 and the underwater structure 104. As the tether 106 pulls the structural member 117 down, the offset cylinders 130 displace hydraulic fluid into an accumulator or a gas charged accumulator which resists and provides a restoring force to cycle the structural member 117, in some embodiments, back up.

In a third case, the hydraulic system has suffered a net loss of fluid via external leaks, and the fluid balance has accumulated on the bore side of the active input cylinder. The maximum force against the vane is developed when the longitudinal chord 42 of vane 16 is perpendicular to the direction of flow. FIG. 4 is an isometric detail view of a direction control mechanism utilizing roller stops. Direction control mechanism 20 is not limited to stops and magnets. The shape and chord length of the vane is dependent on the flow conditions. Cavitation and inefficiency will occur when vane 16 intercepts the flow lines. In some implementations, multiple concatenated power dissipation networks 170 may be selectively engaged based on the amount of power that must be shed per cycle. Depicted schematically, the power transfer system 100 may include fewer or more components to implement less or more functionality in other embodiments.

The exact equations of concavity will necessarily be determined, therefore, mathematically or empirically for the particular flow conditions or range of flow conditions in which the system is expected to operate. It appears that the proper timing of the stroke of swing arm 18 effects the power output. Que me tomo para el dolor de espalda .
