Abstract: The invention seeks to enable a coupling to be made in which assembly forces during assembly of the gasket are small, even though the coupling is of large size, e.g. having a diameter equal to 50 mm. To achieve this object, the invention proposes making a gasket whose envelope in section presents a surface for bearing against the bottom of a groove that is smaller than the surface it presents for bearing against the fluid-feed endpiece. A fluid transfer coupling is for making between a fluid-feed endpiece and a connection tube, the coupling including an annular groove for housing the gasket, the gasket presenting a bearing face for bearing against the bottom of the groove and a bearing face for bearing against the endpiece, the groove presenting an opening and a groove bottom that is substantially flat and smaller in size than the opening.

Abstract: A one piece, double gland, quad lobe design gasket system for use in a projection system that redundantly seals in the liquid present in a coupler supporting a projection lens in alignment with a projection optical signal generation device (e.g., a Cathode Ray Tube). The coupler defines a cooling chamber between said projection lens and said projection signal generating device and is filled with liquid in order to transport the optical signal between the projection optical signal generation device and projection lens while minimizing contrast distortion. In order to prevent leaking from the cooling chamber between the coupler and projection signal generation device, an improved sealing system is used by providing two separate channels in the coupler and using the integral double gland, quad lobe gasket. Each gland is placed in a corresponding groove in the coupler thus creating two separate lines of seal that keeps the liquid in the coupler from leaking out.

Abstract: A membrane seal includes a pair of confronting annular sealing grooves. A first annular sealing member is received in one of the oppositely facing sealing grooves and a second annular sealing member is received in the other of the oppositely facing sealing grooves. The first and second sealing members are sealably connected together by an annular membrane. A pressure difference across the membrane forces the first and second sealing members into contact with a side wall of each of the oppositely facing sealing grooves to effect a seal. Known sealing members have a circular cross-section but in the present invention at least one of them has an oval cross-section. The oval cross-section gives the first and/or second sealing member(s) a larger zone of contact with the oppositely facing sealing groove(s). This reduces the amount of wear on the first and/or second sealing member(s) and produces a better seal.

Abstract: A fluid container assembly design has a wide tolerance variation in the width of an open seal gap between opposed sealing surfaces of different assemblies. A resilient seal is provided with a generally rectangular central section partially supported within a groove and partially unsupported by excessive extension beyond the groove. To avoid buckling, the extending portion includes resilient stabilizers including barb-like projections. These resiliently engage a component surface adjacent the groove to stabilize the extending portion and prevent buckling. This allows the seal to compress over its total height to seal the gap between the bottom of the retaining groove in one component and the opposite sealing surface of the other assembly component while the stabilizer projections yield to avoid involvement in the sealing function and act only to prevent buckling of the seal unsupported portion. Exemplary applications for engine rocker covers and oil pan-crankshaft seal gaps are disclosed.
