ABSTRACT:
A piston space (7) of the consumer (10) has two delivery lines (6, 8), such that when the consumer (10, 12, 13, 14) is not actuated, pressure medium flows continuously via the second delivery line (6) through the piston space (7) and into a pressure medium reservoir (2) to maintain a consumer (10, 12, 13, 14) in readiness for actuation and operate it with uniform pressure medium viscosity. Pressure medium is passed into the piston space (7) through both the first pressure medium delivery line (8) and the second pressure medium delivery line (6) to actuate the consumer (10, 12, 13, 14).
