Abstract

An actuator comprises a housing (8) which contains a screw mechanism (9) and a motor (10) which is drivably connected to the screw mechanism (9), said screw mechanism providing a linear movement in response to a rotational movement of the motor, and comprising a screw (12) and a nut (13) one of which is supported rotatably with respect to the housing (8). The linearly displaceable member of the screw mechanism is drivingly connected to a pump mechanism for providing a flow of medium.
