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).
Claims4
A hydraulic system, in which pressure medium from a pressure medium reservoir (2) is delivered by a pressure medium source (1) to at least one consumer (10, 12, 13, 14) with a piston space (7) and at least two pressure medium delivery lines (6, 8), such that when the at least one consumer (10, 12, 13, 14) is in a non-actuated condition a first pressure medium delivery line (8) is connected to the pressure medium reservoir (2) and a second pressure medium delivery line (6) is connected to the pressure medium source (1), when the at least one consumer (10, 12, 13, 14) is in an actuated condition, the first and second pressure medium delivery lines (6, 8) are both connected to the pressure medium source (1) and the pressure level in the first and second pressure medium delivery lines (6, 8) is the same.
