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 valve body member with a through passageway including another valve chamber open at one end. A restricted flow passage is at the other end of the valve chamber. An outlet opening is connected to the flow passage. The valve body member is connected to the valve body so that a pressure port in the valve body communicates with the open end of the valve chamber. A valving member is slidable in the valve chamber and has a nose that opens and closes the restricted flow passage. A head of the valving member is located in the open end of the valve chamber. Portions establish fluid flow through the fill valve when the restricted flow passage is open. A spring acts on the valving member to urge it toward an open position. Fluid pressure in the pressure port acts on the head and holds the valving member closed until the force of the fluid pressure is overcome by the spring force. The spring holds the valving member open to permit the tank to be evacuated and charged with pressurized fluid.

Abstract: The invention pertains to a fitting consisting of a tubular body which may be readily installed over the end of a smooth wall conduit and removed therefrom and may be quickly connected to a standard unisex adapter mounted on the end of a hose line to place the conduit and hose line in fluid communication. The fitting includes a positive lock for attaching the fitting to the conduit and a flexible retainer is employed for safety purposes to resist "blow off".

Abstract: A coupling for use with pressurized systems permitting coupling of valved coupling parts even though one of the parts may be under high pressure. An axially reciprocal valve which automatically opens upon the coupling halves being connected is guided within a shell within the pressurized coupling half and a sealed relationship between the valve and shell minimizes the area of valve surfaces exposed to the pressurized medium reducing the axial forces imposed upon the valve toward the closed position. A bleed valve communicating with the valve interior permits valve operation with hydraulic systems in the event of seal leakage.
