| 摘要 |
The invention relates to a valve, especially a proportional pressure control valve, comprising a valve housing ( 38 ) provided with at least three fluid connections ( 1, 2, 3 ). The valve can be connected to a hydraulic drive system with a pre-determinable minable consumer pressure. The aim of the invention is to create a valve that can perform reliable valve switching functions even for low-viscous fluid media, and to reduce the susceptibility to disturbance variables. To this end, a valve piston ( 56 ), which is actively connected to a pilot seat ( 58 ) by means of an energy accumulator ( 62 ), can be controlled by means of a control device ( 40 ), and the consumer pressure on a fluid connection ( 1 ) acts at least on the valve piston ( 56 ) in such a way that, according to the consumer pressure and the actuating force of the control device ( 40 ), a fluid can flow between the two other fluid connections ( 2 and 3 ) in both directions inside the valve housing ( 38 ).
