Abstract
A fluid pressure regulator includes a housing having an inlet and an outlet, a valve assembly disposed in the housing, and one or more check valves disposed within the housing. The one or more check valves may be closed when a regulator inlet pressure is greater than a regulator output pressure. When the regulator output pressure is greater than the regulator input pressure, the one or more check valves may open and flow may occur from the outlet of the fluid regulator to the inlet of the fluid regulator, even if the valve assembly is in a closed position.
Claims20
A fluid pressure regulator comprising:
- a housing including an inlet and an outlet;
- a valve assembly disposed in the housing;
- and
- one or more check valves disposed within the housing;
- wherein the one or more check valves are closed when a regulator inlet pressure is greater than a regulator output pressure;
- and when the regulator output pressure is greater than the regulator inlet pressure, the one or more check valves open and flow occurs from the outlet of the housing to the inlet of the housing, even if the valve assembly is in a closed position.
A fluid pressure regulator comprising:
- a housing including an inlet and an outlet;
- a valve assembly disposed in the housing and including a valve body;
- and
- one or more check valves disposed in one or more respective fluid passages of the valve body;
- wherein the one or more check valves provide a fluid flow path between the outlet and the inlet if an outlet pressure is above a threshold value, even if the valve assembly is in a closed position.
