Abstract

A gas valve assembly with integrated pressure regulator is provided. The gas valve assembly includes a pressure regulator and a gas valve module. The pressure regulator and gas valve modules each include cast housing bodies. The cast housing bodies have cast in mounting holes and assembly features that allow for the assembly of the gas valve assembly without secondary machining operations.

First claim

What is claimed is:

1. A gas valve assembly, comprising:
a pressure regulator;
a valve module having a housing body, the pressure regulator mounted to the valve module along a mounting axis defined by the valve module; and
wherein a mounting arrangement is formed between the pressure regulator and the housing body of the valve module such that the pressure regulator is removably mounted to the housing body and rotationally fixed about the mounting axis and such that the pressure regulator is capable of only a single orientation relative to the valve module;
wherein the mounting arrangement includes a mounting boss and a recess, the boss received within the recess, and wherein the mounting boss defines a main port for a fluid flow into the valve module.

2. The gas valve assembly of claim 1 , wherein the mounting boss projects from a side wall of the housing body of the valve module.

3. The gas valve assembly of claim 2 , wherein the recess is formed into a port of a housing body of the pressure regulator.

4. The gas valve assembly of claim 3 , wherein a seal groove surrounds the mounting boss.

5. The gas valve assembly of claim 1 , wherein the pressure regulator and valve module each include at least one integral cast in mounting bracket.

6. The gas valve assembly of claim 1 , wherein the housing body has at least one cast in cavity, the cavity defining an opening and adapted to receive a valve operator.

7. The gas valve assembly of claim 6 , wherein the opening of the at least one cast in cavity is surrounded by a cast in seal groove and a plurality of cast in mounting holes.

8. A gas valve assembly, comprising:
a pressure regulator;
a valve module having a housing body, the pressure regulator mounted to the valve module along a mounting axis defined by the valve module; and
wherein a mounting arrangement is formed between the pressure regulator and the housing body of the valve module such that the pressure regulator is removably mounted to the housing body and rotationally fixed about the mounting axis and such that the pressure regulator is capable of only a single orientation relative to the valve module;
wherein the mounting arrangement includes a mounting boss and a recess, the boss received within the recess, and wherein the mounting boss defines a main port for a fluid flow into the valve module; and
wherein the mounting boss has a non-circular cross section, and the recess is defined by an inner peripheral wall of a port of the pressure regulator, wherein the recess has a non-circular periphery.

9. A gas valve assembly, comprising:
a pressure regulator;
a valve module having a housing body, the pressure regulator mounted to the valve module along a mounting axis defined by the valve module; and
wherein a mounting arrangement is formed between the pressure regulator and the housing body of the valve module such that the pressure regulator is removably mounted to the housing body and rotationally fixed about the mounting axis and such that the pressure regulator is capable of only a single orientation relative to the valve module;
wherein the mounting arrangement includes a mounting boss and a recess, the boss received within the recess, and wherein the mounting boss defines a main port for a fluid flow into the valve module; and
wherein the mounting boss has generally U-shaped cross section, and wherein the recess has a generally U-shaped periphery which corresponds to an outer periphery of the mounting boss.

10. A gas valve assembly, comprising:
a pressure regulator, the pressure regulator comprising a cast housing body having at least one integral cast in mounting bracket, the at least one integral cast in mounting bracket adapted to mount the gas valve assembly within an interior of an appliance;
a valve module having a cast housing body, the pressure regulator removably mounted to the cast housing body of the valve module, the cast housing body having at least one integral cast in mounting bracket, the at least one integral cast in mounting bracket adapted to mount the gas valve assembly within the interior of an appliance; and
wherein a mounting boss projects from a side wall of the cast housing body of the valve module, the mounting boss defining a main port for a fluid flow into the valve module.

11. The gas valve assembly of claim 10 , wherein the at least one integral cast in mounting bracket of the housing body of the valve module includes an open ended slot.

12. The gas valve assembly of claim 10 , wherein the at least one integral cast in mounting bracket of the housing body of the valve module includes a plurality of integral cast in mounting brackets.

13. The gas valve assembly of claim 10 , wherein the at least one integral cast in mounting bracket of the housing body of the pressure regulator includes a mounting hole at a distal end thereof.

14. The gas valve assembly of claim 10 , wherein the pressure regulator is mounted to the valve module via a mounting arrangement, the mounting arrangement adapted to allow only a single orientation of the pressure regulator relative to the valve module, wherein the mounting arrangement includes the mounting boss and a recess, the boss received within the recess.

15. The gas valve assembly of claim 14 , wherein the recess is formed into a port of a housing body of the pressure regulator.

16. The gas valve assembly of claim 10 , wherein the housing body of the valve module has at least one cast in cavity, the cavity defining an opening and adapted to receive a valve operator.

17. The gas valve assembly of claim 16 , wherein the opening of the at least one cast in cavity is surrounded by a cast in seal groove and a plurality of cast in mounting holes.

18. A method of manufacturing a gas valve assembly, comprising:
providing a valve module having a cast housing body, wherein the cast housing body of the valve module includes a cast in mounting boss defining a main port for a fluid flow into the valve module;
providing a pressure regulator having a cast housing body, wherein the cast housing body of the pressure regulator includes a cast in recess, wherein an inner peripheral wall of the cast in recess matches an outer peripheral wall of the cast in mounting boss such that the pressure regulator is capable of only a single orientation relative to the valve module;
installing the pressure regulator onto the valve module by inserting the cast in boss of the housing body of the valve module into the cast in recess of the housing body of the pressure regulator; and
fixedly securing the pressure regulator to the valve module.

19. The method of claim 18 , wherein the step of securing includes securing the pressure regulator to the valve module using mounting hardware.
