Title: BLEEDER VALVE
Abstract:
A bleeder valve (300) for controlling a gas outflow from the interior of a pressurized container (302) to an ambient atmosphere through an exhaust conduit (303) comprises: a valve seat (309) associated with said exhaust conduit (303), a movable lid (311) having a central closure portion (313) and a peripheral sealing surface (315) cooperating with said valve seat (309), and an actuating mechanism (316) connected to said lid (311) for moving said lid between a closed position on said valve seat and an open position distant from said valve seat. The lid comprises a deflection portion (317) at the periphery of said sealing surface. The deflection portion comprises a deflection surface (318) inclined relative to a tangent (Tsl) to said sealing surface (315) by an included angle (a) less than 180 degrees for imparting to a gas outflow passing between said valve seat (309) and said lid (311) a velocity component which is perpendicular or opposite to the initial opening movement of said lid. The central closure portion (313) is recessed with respect to said sealing surface (315).
