Abstract: A sealing arrangement is provided and includes a slide ring seal, and a counter ring that is accommodated in a holder that is provided with a presser sleeve via which, in an installed state, the sealing arrangement is seated with a press fit on a component that is to be sealed. The presser sleeve is disposed between a sealing zone and a holding zone, with the sealing zone being made of a material that has a higher elasticity than does the presser sleeve.

Abstract: A deep pile, fur-like material is used in an automated vehicle washing apparatus to simulate a vehicle hand wash. The vehicle washing apparatus uses a resilient drum constructed of a pair of spaced apart disks and an elastic cord which extends between the disks around the circumference of each disk. A cover is wrapped around the cord, and over a portion of the plates, so that the cover rotates with the plates, which rotate with the shaft. The cover includes a plurality of shingles which extend radially outwardly under centrifugal force. The shingles are preferably made of a deep pile fur-like material. Alternatively, a foam core member wrapped around a rotatable support carries a cover which is made of deep pile, fur-like material.
Abstract: A disc brake caliper seal arrangement wherein an annular seal is provided between the caliper housing and the outside diameter of the piston provided therein. The seal provides a rollback function which returns the piston to a given running clearance between the disc rotor and brake pads after actuation of the brake. The seal is provided in a substantially square or rectangular cross-sectional configuration and is disposed in a seal groove of the caliper housing. The seal is provided with annular recesses on the ends of the parallel sides of the seal adjacent to the outside diameter of the piston. The central portion of the side of the seal which engages the outside diameter of the piston is provided with a circumferential groove. The recesses provide space of sufficient volume for the seal to deflect into before encountering the straight groove side wall, thereby eliminating the need for a machined chamfer in the housing groove.

Abstract: A relatively stationary segmented turbine engine shroud, nozzle or frame assembly is sealed against the passage of cooling air into the exhaust gas flowpath by a plurality of spline seals which cooperate with an annular stationary brush seal. The spline seals provide sealing between axially extending confronting edges of adjacent segments while the brush seal provides continuous circumferential sealing around the segments and spline seals.
Abstract: A mechanical split seal includes a tapered carbon split seal ring and a silicon carbide split mating ring. The tapered seal ring is compressed by a tapered seal ring shell which has a split "O" ring disposed in the taper to provide even force and improved sealing. The shell is biased toward the seal ring by multiple springs retained by a non-split cup. The mating ring is supported by a gland which includes a split gland packing assembly for compressing packing material onto the shaft. Used as a pump seal, the seal can be cooled by circulation created by the fluid supplied from either the pump input or output.
Abstract: A seal for providing a fluid tight seal between a pair of relatively rotatable components has a first seal face member mounted in fixed axial and rotational relationship and sealed with respect to one component and a second seal face member sealed with respect to said other component, the second seal face member being sealed with respect to its associated component by a radially extending diaphragm, the diaphragm being disposed on the high pressure side of the seal face members, so that when subjected to fluid under pressure the force acting on the diaphragm will urge the second seal face member into engagement with the first seal face member.
