Abstract
An improved pressure regulator suitable for use with paint ball guns comprises a hollow valve body and a valve mechanism for selectively releasing gas from a gas source to an output. The valve body has a unitary coupling portion, a fill port, an output port, a discharge opening, and an inlet opening. The valve body defines two confined flow passageways. The first connecting the plug chamber and the discharge opening. The second connecting the fill port and the inlet opening. The valve mechanism includes a regulator seat, a polymeric valve plug movable within the plug chamber for sealing engagement with the regulator seat, and a fluid barrier axially movable with respect to the valve body. A spring is provided for urging the fluid barrier toward the regulator seat.
