DEVICE FOR CONTROLLING A COMPRESSED GAS CONSUMING CIRCUIT AND VACUUM GENERATOR USING SAME

摘要

The invention concerns a device controlling the opening and closure of a compressed gas consuming circuit (U) comprising a two-state cut-off valve (2), normally closed, said cut-off valve (2) including a control chamber (2a) and a counter-control chamber (2b) permanently communicating with a compressed gas source (P), directly for the control chamber (12a) and via a choke (6) for the counter-control chamber (2b), the latter including a bleed bypass (8) opened or closed by a dual-position two-port valve (9).
