Transmission means provide a unidirectional direction of rotation in the energy generator when the moving direction 10 of the running rod changes. It is within the scope of the invention that the “wave-powered generator” and the “generator” may just as well produce energy of some other form, for example by a pump supplying 25 liquid under pressure. WO 2008/115066 PCT/N02008/000076 8 Figure 3 shows an exemplary embodiment, in which the main module 1 is placed on land 60, the primary driving line 4 be ing extended via sheaves 91, 91a to one end of the running rod 2 which is connected, at its other end, to the ballast 70 5 via the driving line extension 4a. The driving line extension 4a is passed over a sheave 91b which is arranged on a tower la, and here the ballast is hangingly disposed in the tower la.
Further, the main module is provided with a generator 19. A running rod 2 is arranged vertically, extending through the WO 2008/115066 PCT/N02008/000076 6 main module 1. The main module 1 is provided with several supporting devices for the running rod in the form of guiding sheaves 13 which are arranged to roll on one of the side sur faces of the running rod 2. By means of a driving line 4, the 5 running rod 2 is connected to a float 3 floating on a water surface 5. The main module is further provided with two sheaves 15a, 15b. The main module 1 comprises transmission means 10 in the form of two free-wheels 16a, 16b, each coaxially connected to a 10 sprocket 16c and to the sheaves 15a, 15b, and interconnected by a drive chain 17 via the two sprockets 16c. One free-wheel 16a is also connected to a gear 18a which is connected via gearwheels 18b, 18c, 18d to the drive shaft 19a of the gen erator 19. The sheaves 15a, 15b are arranged to engage a cog is ged portion (not shown) on the running rod 2, the cogged por tion extending along substantially the entire longitudinal extent of the running rod 2. The transmission means 10 pro vide for the drive shaft 19a of the generator 19 to be ro tated when the drive 10 is set into rotation by the vertical 20 movement of the running rod 2 relative to the main module 1. It is obvious to a person skilled in the art that the length of the running rod 2 must be adapted for the dimensioning wave height in the area in which the wave-powered generator is to be disposed.

25 The free-wheels 16a, 16b are arranged to be drivingly engaged in a first direction of rotation. By the interconnection of the WO 2008/115066 PCT/N02008/000076 7 free-wheels 16a, 16b by way of the drive chain 17, the first and second free-wheels 16a, 16b will alternately provide for the drive shaft 19a of the generator 19 to be kept in a uni directional direction of rotation as the running rod alter 5 nates between the upward and downward directions of motion. Inyeccion para el dolor muscular . 10 By the upward movement of the first float 3 by the waves 5, the running rod 2 is lifted as the sheaves 15a, 15b rotate on the side surfaces of the running rod 2. Because of the orien tation of the free-wheels 16a, 16b and the interconnection of the sprockets 16c via the drive chain 17, the rotation of 15 only one of the sheaves 15a, alternatively 15b, will be transmitted to the drive shaft 19a of the generator 19 via the gearwheels 18a, 18b, 18c, 18d as the free-wheel 16a, al ternatively 16b, on the other one of the sheaves 15a, alter natively 15b, is running freely.
Thereby a uniform direction of rotation is maintained in the generator 19. 30 There are other possibilities for maintaining a uniform di rection of rotation in the generator 19 by an alternating di rection of motion of the running rod 2. For example, sheaves WO 2008/115066 PCT/N02008/000076 9 may be used only on one side of the running rod 2, this/these being provided with two free-wheels (not shown) arranged in such a way that, for example, one free-wheel is rotating clockwise and the other one is rotating anti-clockwise, and s one free-wheel is transmitting rotation via an intermediate wheel, so that the opposite direction of rotation of the sheave is turned into the right direction.
0 In the following description the terms “wave-powered generator” and “generator” are used in part for devices which are arranged to produce electrical current. Furthermore, the device includes 5 transmission means which are arranged to translate the rotating motion of the at least one sheave into rotation of the at least one generator; and a float which is floatingly disposed in an area by waves and is connected to the running rod by a driving line substantially of tensile strength.

Throughout the description and claims of the specification, the word “comprise” and variations of the word, such as “comprising” and “comprises”, is not intended to exclude other additives, components, integers or steps. PatemD.doc 2 the heavy loads inflicted on a wave-powered generator by the waves, and the efficiency has been too poor. To prevent a breakdown, it has been attempted to move the wave-powered generator to areas with “calmer” sea and weather conditions. WO 2008/115066 PCT/N02008/000076 5 Preferably, the distance between the first and second floats substantially corresponds to the wave frequency and wave length, so that when the first float is on a wave crest, the second float is in a wave trough.
