Gasket retainer for surface mount fluid component
A gasket retainer that is absent sharp corners, has apertures of reasonable dimensional tolerance, and may be conveniently made by a variety of manufacturing processes. The retainer is made from thin flat springy material that readily returns to form after slight bending. Representative gasket capturing apertures are of smoothly non-convex outline with major dimension sufficiently large to allow passage of a ring shaped gasket turned on edge and minor dimension sufficiently small to engage, on approximately opposite circular segments that each engage along less than one third of a gasket circumference, a cavity or groove on the outside diameter periphery of the gasket turned flat parallel to the retainer material sheet. Fasteners may be retained by similar apertures.
1. A gasket retainer for use in a fluid delivery system, comprising:
a base member formed of a substantially flat sheet of material;
a gasket-capturing major aperture having a non-convex periphery disposed in said base member; and
a circular element;
wherein the gasket-capturing major aperture comprises a major diameter sufficiently large to allow passage of the circular element therethrough and a minor diameter sufficiently small to engage a cavity, groove, or thread on the outside diameter of said circular element;
and wherein the base member is configured to be flexed and then released during the installation of the circular element, wherein the gasket capturing major aperture is configured to flex with the base member, and wherein the minor diameter is sufficiently large to allow passage of the circular element therethrough when the base member is flexed.
2. The gasket retainer as recited in claim 1 , wherein the gasket capturing major aperture is elliptically shaped and smoothly concave.
3. The gasket retainer as recited in claim 1 , wherein the base member comprises stainless steel.
4. The gasket retainer as recited in claim 1 , wherein the base member is rectangular shaped.
5. The gasket retainer as recited in claim 1 , wherein the gasket capturing major aperture comprises a first gasket capturing major aperture and the gasket retainer further comprises a second gasket capturing major aperture.
6. The gasket retainer as recited in claim 1 , further comprising at least one fastener aperture.
7. The gasket retainer as recited in claim 1 , further comprising a pair of fastener apertures.
8. The gasket retainer as recited in claim 7 , wherein the pair of fastener apertures are diametrically opposed across the gasket-capturing major aperture.
9. A gasket retainer for use in a fluid delivery system, comprising:
a base member formed of a substantially flat sheet of material; and a gasket-capturing major aperture having a non-convex periphery disposed in said base member;
wherein the gasket-capturing major aperture comprises a major diameter sufficiently large to allow passage of a circular element therethrough and a minor diameter sufficiently small to engage a cavity, groove, or thread on the outside diameter of said circular element, and comprises approximately one-half of a larger ellipse which is truncated along the minor diameter by a straight portion blended into corner curves at opposing ends of the straight portion, and wherein the base member is configured to be flexed and then released during the installation of the circular element, wherein the gasket capturing major aperture is configured to flex with the base member, and wherein the minor diameter is configured to be sufficiently large to allow passage of the circular element therethrough when the base member is flexed, wherein the gasket capturing major aperture comprises a first gasket capturing major aperture and the gasket retainer further comprises a second gasket capturing major aperture.
10. The gasket retainer as recited in claim 9 , wherein the base member comprises stainless steel.
11. The gasket retainer as recited in claim 9 , wherein the gasket-capturing major aperture is D-shaped.
12. The gasket retainer as recited in claim 9 , wherein the base member is rectangular shaped.
13. The gasket retainer as recited in claim 9 , further comprising at least one fastener aperture.
14. The gasket retainer as recited in claim 9 , further comprising a pair of fastener apertures.
15. The gasket retainer as recited in claim 14 , wherein the pair of fastener apertures are diametrically opposed across the gasket-capturing major aperture.
16. A gasket retainer for use in a fluid delivery system, comprising:
a base member formed of a substantially flat sheet of material; and
a gasket-capturing major aperture having a non-convex periphery disposed in said base member;
wherein the gasket-capturing major aperture comprises a major diameter sufficiently large to allow passage of a circular element therethrough and a minor diameter sufficiently small to engage a cavity, groove, or thread on the outside diameter of said circular element, and comprises approximately one-half of a larger ellipse which is truncated along the minor diameter by a large radius portion blended into corner curves at opposing ends of the large radius portion, and wherein the base member is configured to be flexed and then released during the installation of the circular element, wherein the gasket capturing major aperture is configured to flex with the base member, and wherein the minor diameter is configured to be sufficiently large to allow passage of the circular element therethrough when the base member is flexed, wherein the gasket capturing major aperture comprises a first gasket capturing major aperture and the gasket retainer further comprises a second gasket capturing major aperture.
17. The gasket retainer as recited in claim 16 , further comprising a pair of fastener apertures.
18. The gasket retainer as recited in claim 17 , wherein the pair of fastener apertures are diametrically opposed across the gasket-capturing major aperture.
