In the first pair of cylinders these modes have been marked (Ds) and (ds), in second pair of cylinders (Dm) and (dm), and in third pair of cylinders (Dg) and (dg). FIG. 2a presents a tooth coupling assembly between the two halves of the reciprocating panel 2. The actuating mechanism 6 comprises the lever mechanism 8 with a pair of mutually similar circular coupling elements 8 a that act as toothed couplings and have a central hole and a rim with a toothed outer side. As mentioned above each circular coupling element 8 a acts as a toothed coupling and has a central hole and a rim with a toothed outer side. Each coupling element 8 a is coupled in the gap 2 a to a corresponding circular toothed coupling element 2 b that has been fastened onto the inner end surface of each half of the panel 2 so that the coupling element 2 b makes a reciprocating rotary motion along with the panel 2 about the pivot shaft 3 a that is inserted through the central hole of the toothed coupling elements 2 b and 8 a.

The pivot shaft 3 a can be a common shaft reaching from the first side of the panel 2 to the second side of the panel 2, or it can also be formed from several separate parts, for instance from three separate parts so that one part is at each outer side of the panel 2 and one common shaft part to both the halves of the panel 2 is horizontally in the middle of the panel 2. The panel 2 and the pivot shaft 3 a rotate back and forth together simultaneously and at the same speed of rotation. The pusher ends 6 e, 6 f are only arranged to push the power transmission mechanism of the PTO units 7 in turns so that when the first pusher end 6 e is pushing the power transmission mechanism of the first PTO unit 7 the second pusher end 6 f is returning from pushing the power transmission mechanism of the second PTO unit 7. The power transmission mechanism of the PTO units 7 in this embodiment is a group of pistons 9 in a group 7 a of hydraulic cylinders 7 h.

Instead of one large hydraulic cylinder and piston the PTO unit 7 of the invention comprises a group 7 a of smaller hydraulic cylinders 7 h that all are fastened to a common end plate 7 g with their open ends or the first ends. The pusher ends 6 e, 6 f are free ends so that they are not fastened or otherwise anchored or fixed to any other part of the arrangement. The structure of the driving and PTO arrangement 5 can be construed also so that the separate connecting mechanism 4 is not needed. The solution of the invention has the advantage that its structure is simple, lightweight and economical and very durable enduring typical fatigue stresses in its neighborhood very well. One prior art solution is shown in the international publication No.

Then, for instance, in the solution of FIG. The first end of the extension 9 d comprises an inwardly or outwardly conical or spherical shape that matches to the outwardly or inwardly conical or spherical shape of the second end of the connecting rod 4 b as described earlier. The piston 9 inside the hydraulic cylinder 7 h comprises a first diameter piston head 9 g whose rod has a hollow space 9 p that comprises a second diameter piston head 9 s whose diameter is smaller than the diameter of the first diameter piston head 9 g, and which second diameter piston head 9 s can move axially independently of the first diameter piston head 9 g. Dolor a la flexion de rodilla . FIGS. 3 and 4 present more precisely the driving and PTO arrangement 5 of the wave energy recovery apparatus according to the invention. FIGS. 5-7 present in an enlarged side view, cross-sectioned, and in a simplified and diagrammatic way the second end of the driving and PTO arrangement 5 of the wave energy recovery apparatus according to the invention.

DETAILED DESCRIPTION OF THE DRAWINGS The basic idea of the present invention is to achieve a lightweight, efficient and extremely durable structure of the wave energy recovery apparatus, and to connect the power-take-off unit or PTO unit and the driving unit together as simply as possible and in a way that makes the removal and installation of the PTO unit easy and fast, and that also makes it possible to protect the structures of the wave energy recovery apparatus easily and fast against stormy conditions, and to achieve a wave energy recovery apparatus that is easily and fast controllable according wave and weather conditions.
When the machinery starts working after a pause a momentary pressure chock arises because the hydraulic fluid cannot run so fast into the pipeline and the fluid has its own inertia. After that the guiding cylinders 4 a and 6 b are fastened to each other and the closing and sealing mechanism 12 is opened, after which the power transmission mechanism, such as the pistons 9 are unlocked inside the hydraulic cylinders 7 h and the first end of the connecting rod 4 b is moved into the guiding cylinder 6 b in a touching contact with the pusher end of the actuating rod 6 a.

At first the PTO unit 7 is descended onto the base 1 and fastened at its place. A damping element 20 is installed into the hollow center space 9 j to dampen the axial motion of the damping piston 9 h when the pressure increases in the pressure space 9 a and the damping piston 9 h moves inwards in the hollow center space 9 j.
The wave energy recovery apparatus according to the invention is suited very well for instance to be used in connection with a panel or flap or essentially plate-like wing element, later called shorter only as panels, hinged with its lower edge to make a reciprocating movement caused by wave energy or tidal energy of seawater. That kind of pressurized water can be used as working medium for various tools us such, or for instance in devices for desalination purposes. In that case there are 26 different alternatives to combine the use of the cylinder pairs and their piston heads for controlling the energy capturing. The hydraulic PTO unit 7 is connected water tightly and co-axially to the free end of each guiding cylinder 6 b.
As mentioned above the driving and PTO arrangement 5 comprises the actuating mechanism 6 and one or more hydraulic PTO units 7, in this example there are two PTO units 7 that are mutually similar and placed opposite to each other at the different sides of the panel 2 in the direction of the reciprocating motion of the panel 2. In addition to the lever mechanism 8 the actuating mechanism 6 comprises the rectilinear actuating rod 6 a, which can be for instance a steel pipe with a strong wall. In that situation the pistons 9 are their utmost open position and the volume of the pressure spaces 9 a of the hydraulic cylinders 7 h is at their maximum. In very powerful conditions both the hydraulic cylinders can be used together.

That feature can be used for instance when a part of hydraulic cylinders and pistons needs repair of maintenance, or when apparatus is controlled according to weather or wave conditions. Thus, for instance the shape of the second pusher end 6 f of the actuating rod 6 a is in the longitudinal direction of the actuating rod 6 a outwardly conical or spherical and correspondingly the first end 4 d of the connecting rod 4 b is inwardly conical or spherical, or vice versa.

The size here means the inner diameter of the hydraulic cylinders 7 h. In use, the panel oscillates in response to wave action, and the driving rods are driven to cause hydraulic fluid in the hydraulic cylinders to be pressurized by the action of the pistons moved by the driving rods. FIG. Dolor de cadera ingle y rodilla . 14 presents in a front view and in a simplified and diagrammatic way another end plate with cylinders of the cylinder block of the power-take-off arrangement according to FIG. The number of hydraulic cylinders 7 h in the cylinder block 7 a is preferably an even number, for instance 2, 4, 6, 8 or 10 or even more. Thus, for instance, (Ds) means the smaller cylinder head 9 s together with the larger cylinder head 9 g in the smallest pair of cylinders and (ds) means the smaller cylinder head 9 s only of the smallest pair of cylinders.
