Abstract (en)
[origin: DE4128656A1] The hydraulic controlling device proposed has a differentially acting cylinder (11), the annular space (14) in the cylinder being acted on continuously by pressure produced by a pump (16). The pressure space (18) in front of the piston large area is connected to the pump by a connection line (41). Branching off from this connection line (41) is a side line (19) leading to a control valve (21). The other side of this control valve is connected to a return line (26). Appropriate control of the control valve enables the pressures in the side line (19) and hence in the pressure spaces (14, 18) of the differentially acting cylinder to be varied.
