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; and a gasket-capturing aperture having a smoothly non-convex periphery, which does not have a continuously changing curvature, the periphery being defined by three substantially identically shaped periphery portions and three curved radii joining opposing ends of each of the three substantially identically shaped periphery portions, so that the aperture is substantially triangular in appearance, the aperture defining a sufficiently sized opening to allow passage of a circular element therethrough between each of the substantially identically shaped periphery portions and opposing aperture periphery radii while simultaneously maintaining sufficiently small clearance between adjacent pairs of the identically large curvature periphery portions to engage a cavity, groove, or thread on the outside diameter of that circular element, a gasket being captured within said aperture; and
at least two fastener apertures disposed on opposing sides of said gasket-capturing aperture.
2. A gasket retainer according to claim 1 , wherein the three substantially identically shaped periphery portions have a relatively large curvature which appear substantially straight.
3. A gasket retainer according to claim 1 , wherein the non-convex aperture appears as a Reuleaux triangle or tri-oval shape.
4. The gasket retainer as recited in claim 1 , wherein the gasket is comprised of a different material than the gasket retainer.
5. The gasket retainer as recited in claim 1 , wherein the gasket is removably separate from the gasket retainer.
6. The gasket retainer as recited in claim 1 , wherein the gasket is circular.
