Abstract:

A valve for a pressurized canister includes a housing having a central aperture extending therethrough, a first set of external threads, and a second set of external threads. A sealing member is positioned in an axially outward end of the central aperture and is axially moveable. A first spring biases the pin axially outwardly. An axially slidable member is received and axially movable in the central aperture. A second spring biases the axially slidable member outwardly. A threaded member in an aperture in the housing engages the axially slidable member. Each of a plurality of radially moveable members is positioned in an aperture in the housing and is radially moveable between a lip on the aperture and the second spring. An exterior surface of an inner end of the axially slidable member engages and forces each radially moveable member into contact with the lip when the threaded member is tightened.
