Abstract: A shaft seal assembly for sealing a moving shaft of a fluid consumer includes a seal case movable relative to a mating surface of the shaft, a biasing force that biases the seal case towards the mating surface, and a seal at least partially disposed in the seal case. In a dynamic condition, when fluid pressure against the seal case is equal to or greater than a threshold pressure, the seal case sealingly separates from the mating surface, and the seal is forced into sealing engagement against the mating surface of the shaft to form a dynamic seal. In a static condition, when fluid pressure exerted against the seal case is less than the threshold pressure, the seal is sealingly engaged against the mating surface to form a static seal, and the seal case is sealingly engaged against the mating surface of the shaft to form an additional static seal.

Abstract: The disclosed principles provide for novel flange gaskets having a mesh filter and methods of manufacture thereof. Disclosed mesh flange gaskets provide a combination of quality seal, even at low clamp loads, with a filter for filtering out unwanted particulates, as well as manufacturing at a low cost. In one aspect, the disclosed principles utilize expanded PTFE, or other similar sealing material, on the outer section of a circular mesh positioned over the central bore of the flange and which is sandwiched between the two halves of a corrugated plastic gasket. The two halves of the flange gasket are then attached to each other with the ePTFE impregnated mesh therebetween. With this composition, the ePTFE impregnated mesh becomes part of the seal of the overall flange gasket. This provides low load sealing on the top and bottom of the gasket against the flanges, and prevents leakage through the middle barrier layer.

Abstract: Provided is a gasket mounting structure capable of preventing a gasket from being mounted in a wrong direction. The gasket mounting structure is configured such that, when a jig 200 is inserted into a gasket 100 from a large-diameter inner peripheral surface portion 124 side, a small-diameter outer peripheral surface portion 210 is press-fitted into an inner peripheral surface of a seal projection 122 to result in a state in which the gasket 100 is held by the jig 200 and, when the jig 200 is inserted into the gasket 100 from a small-diameter inner peripheral surface portion 123 side, the small-diameter outer peripheral surface portion 210 does not reach a position at which the small-diameter outer peripheral surface portion 210 can come into contact with the seal projection 122.

Abstract: The seal spring of the present invention has a dual functionality. The seal spring provides both a sealing property and spring function in use within an electrical connector system, which is accomplished by its elastomeric qualities. The seal spring is preferably comprised of Silicone, EPDM rubber or materials and compositions that provide similar performance during use, or the like. The seal spring of the present invention is not limited or defined into a spring section or a seal section by its geometry. Shown is an implementation of the seal spring within an outer housing and connector assembly. The seal spring compresses and provides adequate spring force against a tab or tabs within the outer housing. The seal spring also functions as an interface seal and an environmental seal during use. The seal spring is, substantially, in its entirety, of a contiguous and continuous single construction. No part or section of the seal spring is made up of welded, soldered, or brazen part or section.

Abstract: The present disclosure provides a sealing ring assembly having ring segments configured to seal a high-pressure region from a lower pressure region of a piston and cylinder device. The sing segments are configured to move radially outward and wear during operation of the piston via the cylinder device. The ring segments include, for example, wedge-shaped features that engage with corresponding wedge recesses in the interfaces between ring segments. The sealing ring assembly may include a high-pressure boundary and a low-pressure boundary. As the sealing ring wears, the ring segments stay engaged with the interfaces, so that ring gaps do not form on the low pressure boundary.
