发明名称 Pressure medium system, in particular hydraulic system
摘要 The invention relates to a pressure medium system, in particular a hydraulic system, having a fluid pump for delivering a drive fluid with a certain delivery flow rate and a certain fluid pressure, and having a control unit which switches the fluid pump on or off in order to set a predefined setpoint value of the fluid pressure, wherein the fluid pump exhibits an inertia-induced overrun when switched off, such that during the overrun of the fluid pump, the fluid pressure still rises while the fluid pump has already been switched off. It is proposed that, during the increase of the fluid pressure to the predefined setpoint value, the control unit switches the fluid pump off before the fluid pressure has reached the predefined setpoint value. The invention also includes a corresponding operating method.

主权项 1. A pressure medium system, with a) a fluid pump for conveying a drive fluid with a certain discharge flow and a certain fluid pressure, b) a control unit, which switches the fluid pump on or off to adjust a predefined target value of the fluid pressure, c) wherein the fluid pump has an inertia-induced overrun during shut-off, so that the fluid pressure still rises during the overrun of the fluid pump, while the fluid pump is already switched off, d) wherein the control unit switches off the fluid pump when increasing the fluid pressure to the predefined target value before the fluid pressure has reached the target value.
