Abstract

In order to obtain a hydraulic power unit of small dimensions and simple construction, particularly adapted for double-acting hydraulic actuators, the pump (A) of the power unit is constituted by a reversible pump, activated, for example, by a reversible electric motor, while the two mouths (B, B min ) of the pump, each of which can operate alternately as a suction mouth and as a delivery mouth, are each connected or connectible, possibly by means of a hydraulic distributor (R), at one side to conduits (C, C min or C sec , C''') for connection to the user and at the other side to the tank (H) for the hydraulic liquid either by means of associated unidirectional valves (F, F min ) opening in the direction of the flow from the tank (H) to the respective mouth (B, B min ), or - parallelly with said unidirectional valves (F, F min ) - by means of associated automatic pressure relief valves (L, L min ).
