Abstract (en)
The invention relates to a hydraulic system for the control of an actuator consisting of a double acting cylinder and piston unit. The control system comprises a bi-directional pump C the opposite outlets C1 and C2 of which are connected respectively with the opposite ends of the cylinder B through a one-way pressure check valve D1. Each end of the cylinder is also connected with a hydraulic reservoir G through a check valve E1 which is also connected with the respective pump outlet C1 so as to close in response to a predetermined increase in the hydraulic pressure between the pump outlet C1 and its respective one-way pressure check valve D1.
