<p>1280111 Valves BENDIX CORP 15 June 1970 [14 July 1969] 28911/70 Heading F2V In a distributor for controlling the flow of pressurized fluid from a container to a life raft, a spring-loaded main valve 26 normally prevents flow from an inlet 14 to outlets 16, 18 and is abutted by a pin 76 the other end of which abuts a vent valve 82 on the end of a spring-loaded piston 62 to normally hold the vent valve open to vent the outlets via port 30. A cross pin 66 in the piston 62 co-operates via roller 68 with a cam slot (60) in a rotatable cam 46 which on rotation by a screw driver slot (48) or a pull cord (49) wound around the cam causes the pin 66 and piston 62 to move downwards to close the vent valve 82 on seat 80 and open main valve 26. Simultaneously a shoulder 86 on the pin 76 moves spring-loaded lever 38 away from the end of a stem 45 of a check valve 28 so that the latter, which is normally held tilted open by the lever 38, may close. A container connected to inlet 14 may be pressurized from a source connected to outlet 16 while outlet 18 is closed by a cap 92 on opening and closing the main and vent valves respectively. Afterwards the outlets are connected to inflation chambers of a life raft after the valves are returned to their normal positions.</p> |
