Abstract

Improvements in fluid-powered drive cylinders, of the type comprising a drive rod attached to a movable piston in a hydraulic cylinder, characterized by also comprising a means, arranged around said hydraulic cylinder, to transmit a control pressure to the liquid of said cylinder hydraulic, effort multiplier device capable of transmitting to said liquid a pressure higher than the control pressure, and a means to interrupt the communication between the hydraulic cylinder and the control pressure transmission medium, during the operation of the multiplier device, to avoid the backward movement of the liquid towards the transmitting medium, all these parts being arranged in a substantially coaxial way in a unit that constitutes the driving cylinder.
