| 摘要 |
The invention concerns an extraction valve (4) for overpressurised gas flowing from a compressed gas reservoir (2), having a valve seat carrier (30), Including a conical valve seat (31) emerging centrally into an outflow chamber (20), having an extraction piston (17), which is mobile in its axial direction (4) at least indirectly via an electromagnetic coil (12), and which includes a valve body (32) cooperating with the valve seat (31), and an inflow chamber (10) for the pressurised gas, The extraction valve according to the invention is characterised in that the inflow chamber (10) is designed totally or partially on the circumference of a central axis (A) of the extraction piston (17) and is connected in the axial direction of the extraction piston (17) against a flow direction (E) of the gas when the extraction piston (17) is in open position, between the valve seat (31 ) and the valve body (32) via an intermediate connection (bores 34) with an intermediate volume (35), which comprises for its own part a connection (opening 38) with the region In which the valve seat (31 ) and the valve body (32) co-operate. |
