| 摘要 |
The invention relates to a valve, especially a valve for high-pressure hydraulics, which comprises a valve bore (3) provided in a valve housing (2). In said valve bore, at least one valve seat (5; 19; 23) is located and separates a guide (8) on the high-pressure side of the valve bore (3) from a guide (12) on the low-pressure side of the valve bore (3). The valve also comprises a valve needle (1), directly actuated by an actuator (4) and guided in the valve bore (3) and having at least one sealing face (9; 28) that cooperates with the at least one valve seat (5; 19; 23). The valve needle (1) is complex and comprises, in the area of the guide (12) on the low-pressure side, at least one sleeve (13; 21, 22; 24, 25). |
