Electro-hydraulic control device

The invention relates to an electro-hydraulic control device having a pressure supply device (2.1, 2.2) for conveying a pressure medium from a reservoir (3) in a main pressure line (4), wherein the promotion of the pressure medium drivable by a by a controllable electric motor (11) pumping element (10 ) is carried out, and with a setting device (5.1, 5.2) for operating at least one hydraulic actuator (6, 7, 8), wherein actuation of the actuator (6, 7, 8) via a (by at least a control valve 23, 24, 25 ; 31, 32; 36, 37; 43) can be produced compound of at least one pressure chamber (22; 29, 30; 34, 35; 42) of the actuator (6, 7, 8) with the main pressure line (4) and / or with a depressurized (26) takes place. For simplification of the control device, the pumping element (10) as a single-acting pressure cylinder (12) is formed in which a via a spindle gear (13) connected to the electric motor (11) piston (14) is guided axially movable and axially on one side a pressure chamber (15) limited, the provided via a with a check valve (16), suction line (17) with the reservoir (3) and via a pressure line (18) with the main pressure line (4) is in communication.
