Abstract
Abstract A pressure vessel includes a threaded aperture in a wall thereof which threadedly receives the outer threaded surface of a cylindrical housing. The housing includes an inlet cylindrical bore which merges across a radial wall into a like bore of larger diameter. A threaded cylindrical cap is threaded over the housing interiorly of the vessel and includes an apertured radial wall providing an outlet. The radial walls of the housing and cap and the larger diameter bore of the housing define a chamber. A hollow cylindrical valve member is slidably mounted within the chamber and includes a plurality of axial grooves in the periphery thereof. A coil compression spring seats on one end of the valve member and the radial wall of the cap to seat the other end of the valve member against the radial wall of the housing to close the grooves to the inlet. The valve member includes a counterbore and a fluid pressure rupturable diaphragm seats against the radial wall of the counterbore and is retained in place by a press fitted retainer ring to block communication between the inlet and outlet through the valve member and cooperatively define with such member a fluid pressure actuated piston. Communication of the inlet with a source of pressure fluid displaces the piston against the spring to fill the vessel through the axial grooves. Pressure relief is obtained when the diaphragm ruptures under a pressure level in the vessel exceeding a predetermined pressure.

Claim 1
Independent Claim
220 words
In combination with a vessel containing pressure fluid, a combined fill and pressure relief valve comprising, in combination, an annular housing assembly received within an opening in a wall of the vessel and including an annular chamber having spaced apertured end walls, one providing an inlet and the other providing an outlet, a hollow annular member slidably received within the chamber with the bore thereof opening to the inlet and outlet, the annular member including a plurality of passages extending between and opening to the ends thereof, resilient means seating between the other end wall of the chamber and one end of the annular member to seat the other end of the annular member against the one end wall of the chamber and close the passages to the inlet, and a fluid pressure rupturable diaphragm closing the bore of the annular member and defining therewith a piston, communication of the inlet to a source of pressure fluid to fill the vessel displacing the other end of the piston relative to the one end wall of the chamber against the resilient means to communicate the inlet and outlet through the passages and fill the vessel, the diaphragm being rupturable upon attainment of a predetermined pressure within the vessel to communicate the inlet and outlet through the bore of the annular member.

In combination with a vessel containing pressure fluid, a combined fill and pressure relief valve comprising, in combination, an annular housing assembly received within an opening in a wall of the vessel and including an annular chamber having spaced apertured end walls, one providing an inlet and the other providing an outlet, a hollow annular member slidably received within the chamber with the bore thereof opening to the inlet and outlet, the annular member including a plurality of passages extending between and opening to the ends thereof, resilient means seating between the other end wall of the chamber and one end of the annular member to seat the other end of the annular member against the one end wall of the chamber and close the passages to the inlet, and a fluid pressure rupturable diaphragm closing the bore of the annular member and defining therewith a piston, communication of the inlet to a source of pressure fluid to fill the vessel displacing the other end of the piston relative to the one end wall of the chamber against the resilient means to communicate the inlet and outlet through the passages and fill the vessel, the diaphragm being rupturable upon attainment of a predetermined pressure within the vessel to communicate the inlet and outlet through the bore of the annular member.
Claim 3
Dependent Claim
244 words
In combination with a vessel containing pressure fluid, a combined fill and pressure relief valve comprising, in combination, an annular housing assembly received within an opening in a wall of the vessel and including an annular chamber having spaced apertured end walls, one providing an inlet and the other providing an outlet, an annular member slidably received within the chamber and including a shouldered annular bore opening to the inlet and outlet, the annular member including a plurality of grooves in the periphery thereof and extending between and opening to the ends thereof, resilient means seating between the other end wall of the chamber and one end of the annular member to seat the other end of the annular member against the one end wall of the chamber and close the passages to the inlet, an annular fluid pressure rupturable diaphragm seating against the shoulder of the bore of the annular member to close such bore and define a piston with the annular member, and means retaining the diaphragm in place, communication of the inlet to a source of pressure fluid to fill the vessel displacing the other end of the piston relative to the one end wall of the chamber against the resilient means to communicate the inlet and outlet through the grooves and fill the vessel, the diaphragm being rupturable upon attainment of a predetermined pressure within the vessel to communicate the inlet and outlet through the bore of the annular member.
