Abstract
In a hydraulic system with a dog clutch (-), a hydraulically operated dog clutch actuator is arranged to alternatively bring the dog clutch into a connect mode or a disconnect mode. The clutch actuator has a piston () reciprocally movable under hydraulic pressure between two end positions, corresponding to the two clutch modes. Pressurized hydraulic oil is supplied to the clutch actuator by a hydraulic power system comprising a pump () driven by an electric motor (). Means are provided in the clutch actuator to decrease the hydraulic pressure acting on the piston () at the approaching by the piston of either of its end positions, so that a hydraulic signal is transmitted back to the hydraulic power system.
