Automatic coupler for pressurized fluid circuit |
摘要 |
An automatic coupler for pressurized fluid circuits is divulged of the type comprising a valve (19) sliding in a body (1), and means for balancing the upstream fluid pressure on the valve. The downstream portion of the latter forms a socket for receiving and sealingly locking a connector (8). The coupler comprises a means for locking the valve in two positions: one in which the valve is open and the other in which it is closed and the socket communicates with the atmosphere, the connector (8) being still locked. Release of the valve from the first position engages a locking means in an intermediate position whose release causes locking in the second position. The coupler of the invention reliably prevents the "whiplash" phenomenon produced, at the time of uncoupling, by the downstream pressure.
