ABSTRACT:
An improved pressure regulator suitable for use with paint ball guns comprises a hollow valve body, a valve mechanism for selectively releasing gas from a gas source to an output, and an ON-OFF control. The valve body has a coupling portion, a regulator seat, an output port, an inlet opening, and sidewalls defining a transverse spool socket. The valve mechanism includes a regulator seat, a valve plug movable within a plug chamber for sealing engagement with a regulator seat, and a fluid barrier axially movable with respect to the valve body. A spool is received in the socket and movable between a first position wherein an internal passage is defined between the gas inlet opening and the regulator seat, and a second position wherein the flow of gas from the gas inlet is blocked.
