| 摘要 |
The invention relates to a valve arrangement (1) having a valve holder (2) on which at least one valve unit (5) is mounted wherein sealing means (47) are interposed. The valve arrangement (1) has a plurality of fluid channels (22) each extending partially in the valve holder (2) and partially in the valve unit (5), below which fluid channels a fluid discharge channel (26, 27) is located which is connected to at least one pressure sink. The fluid discharge channel (26, 27) extends through the sealing means (47) and has a non-return valve (43) which prevents an undesirable return flow of pressure medium. A movable non-return valve member (45) and a valve seat (46) co-operating therewith belong to the non-return valve (43), wherein the valve seat (46) is a one-piece component of the sealing means (47). |
