Abstract:

A regulator and fill valve assembly for filling a fluid pressure tank and for regulating the flow of pressurized fluid from the tank includes a regulator portion having a valve body with a piston chamber. A pressure flow passageway extends from an inlet end to a first end of the piston chamber and an outlet port communicates with the piston chamber. A piston is movable in the piston chamber. A first spring at a second opposite end of the piston chamber urges the piston toward the first end of the piston chamber. A handle is provided for manually controlling the force of the first spring acting on the piston. A check valve assembly is located in the passageway and includes a seat, a valve member, a valve guide and a second spring biasing the valve member and guide towards the seat. The valve member is movable in a direction towards a closed position against the seat by fluid pressure in the passageway and the biasing force of the second spring. A valve check actuator is located between the piston and the valve check.
