摘要

The motor (1) has multiple pistons (6) that together with a cylinder (2) define working chambers (8). The chambers are connected to inlet and outlet lines (18, 24) via an inlet valve (16) and an outlet valve (22) e.g. return valve, respectively. The valve (16) has a closing body separating an inlet-sided pressure chamber from a working-sided pressure chamber. A hydraulic pump (20) and a starting valve (38) reduce effective pressure difference between the pressure chambers for starting-up of the motor. The outlet and starting valves are actuated by a single actuator e.g. actuating magnet (28). An independent claim is also included for a method for controlling a valve-controlled hydraulic motor.
