(ZA9703579-A)      The wave energy converter comprises a buoyant body (11) and an acceleration tube dependent from and attached to the buoyant body. A section of the acceleration tube between the upper and lower ends defines a working cylinder (16) with openings above and below it to allow an unobstructed flow of water between the cylinder and the body of water in which the acceleration tube is immersed.    A piston reciprocates in the working cylinder with one end of each of a pair of resiliently extendible hose pumps (18,19) attached to opposite sides of the piston. The other end of the hose pumps is anchored to the unit. The hose pumps comprise an energy absorbing device.    ADVANTAGE -   Does not require piston rod to transmit force to drive pump.
