Abstract
A gas manifold assembly is disclosed which includes a manifold fitting connected to at least one gas valve. The manifold has an inlet fluid port which branches out into a delivery port. Each delivery port receives a protrusion from each valve which is in turn crimped together to form a collar. A stop offsets the valves from one another to improve manufacturability. One aspect of the invention includes flattening a portion of the protrusion that extends from the valve body in order to engage the fitting which creates an anti-rotation feature once the fitting is crimped. Another aspect of the invention provides seals between the fitting and the valve to increase joint integrity.
Claims28
A dual gas valve assembly comprising:
- a fitting having a fluid delivery bore connected to a central chamber, a first elongated section extending from the central chamber, a second elongated section extending from the central chamber, an axis extending through said first and second elongated sections, a flat crimped portion located at an end of the elongated sections for securing the fitting to first and second control valves, the fitting further including a mounting pad, the mounting pad including a flat surface spaced apart from the central chamber, the flat surface of the mounting pad being substantially parallel to the axis, the flat surface having at least one hole and connectable to a grill;
- a first control valve having a main body with a central fluid passage, a member extending outwardly from the main body, the member having an internal fluid passage;
- and
- a second control valve with a main body with a central fluid passage, another member extending outwardly from the main body with an internal fluid passage.
A gas valve assembly comprising:
- a fitting having an inlet bore and a first cylindrically shaped section with at least one flat portion extending away from the bore;
- a control valve including a main body and a cylindrically-shaped member with at least one flat portion extending outwardly from the main body;
- and
- means for securing the fitting to the control valve including a crimped end of the fitting extending over the flat portion of the control valve.
A dual valve and manifold system comprising:
- a manifold having a first port with a center axis, a second port and a third port, the second port and the third port being symmetrical about the center axis of said first port, the second and third ports each having internal surfaces;
- a valve having a main body with a first longitudinal axis and an integrally formed cylindrically-shaped elongated section extending outwardly from the main body and disposed within the second port in sealing engagement with the internal surface of the second port;
- another valve having a main body with a second longitudinal axis and an integrally formed cylindrically-shaped elongated section extending outwardly from the main body and disposed within the third port in sealing engagement with the internal surface of the third port;
- and
- the manifold further having a flat, crimped portion for engaging the valve.
A dual valve and manifold assembly comprising:
- a manifold having an inlet member and a pair of integral outwardly extending elongated portions, each said portion having an internal surface that defines a port;
- a pair of valves, each said valve having a main body and an integrally formed outwardly extending projection having an inlet passage therethrough, one of the projections being disposed within and sealingly engaging one of the ports, the other of said projections being disposed within and sealingly engaging the other of said ports, and
- the manifold further having a flat, crimped section for connecting the port of the manifold to at least one of the valves.
