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. Movement of the piston toward the first end of the chamber tends to move the valve member to an open position. The assembly also includes a fill valve portion having va…
