Abstract:
1. A fluid transfer device comprising: a housing defining an inlet and an outlet; an actuator having a grasping portion moveable fore and aft, said actuator moveable between first and second positions relative to said housing; a valve assembly disposed in said housing and operatively coupled to said actuator, said valve assembly including a main valve moveable between a closed-main valve position and an open-main valve position in response to movement of said actuator and a pilot valve moveable between a closed-pilot valve position and an open-pilot valve position in response to movement of said actuator wherein said main valve is in said closed-main valve position and said pilot valve is in said closed-pilot valve position when said actuator is in said first position; and a lock operatively coupled to said actuator and moveable between a locked position and an unlocked position, said lock preventing said actuator from moving said main valve from said closed-main valve position to said open-main valve position and preventing said actuator from moving said pilot valve from said closed-pilot valve position to said open-pilot valve position when said actuator is in said first position and said lock is in said locked position; said housing defining at least one catch for receiving said lock in said locked position wherein said lock is disengageable from said at least one catch to allow movement of said actuator from said first position to said second position to move said pilot valve to said open-pilot valve position and to move said main valve to said open-main valve position.
