Abstract
A dispensing valve apparatus and method for rapidly dispensing fluid from a fluid reservoir of a pressure vessel include a piston translatable within a cavity that closes a discharge passage opening the cavity when positioned in a first position and opens the discharge passage to fluid flow from the fluid reservoir when positioned in a second position. The piston may be rapidly repositioned from its position to its second position by venting a cavity disposed between the piston and an actuator cap by selectively opening a check valve to vent the pressure within the cavity to the discharge passage.
