摘要： A compression sensor gasket assembly includes a gasket body having opposite substantially planar sealing surfaces configured for sealing abutment with an engine block and a cylinder head. The gasket body has at least one through opening configured to register with a cylinder bore and a passage extends from an outer periphery of the gasket body between the opposite sealing surfaces. The gasket assembly includes a mounting flange fixed to the gasket body. The mounting flange extends outwardly from one of the substantially planar sealing surfaces. A pressure sensor assembly extends through the passage, and a mounting member is releasably fixed to the mounting flange to operably fix the pressure sensor assembly to the gasket body. The pressure sensor assembly is readily accessible, such that during service the pressure sensor assembly can be removed and serviced without having to remove the cylinder head from the engine block.

摘要： A compression sensor gasket assembly includes a gasket body and a pressure sensor assembly having a sensor tip and an externally threaded portion. The gasket body has opposite sides extending between an opening configured to register with a cylinder bore of an internal combustion engine and an outer periphery. A notch extends into the outer periphery to a recessed surface. A sensor receptacle configured for at least partial receipt of the pressure sensor assembly extends from the recessed surface to the opening. A nut is disposed in the notch with internal threads of the nut being aligned for threaded engagement with the externally threaded portion of the pressure sensor assembly. The nut has bifurcated fingers extending laterally outwardly from an outer surface. The bifurcated fingers have inner surfaces bonded to at least one of the opposite sides of the gasket body to facilitate proper orientation of the pressure sensor assembly.

摘要： A shaft seal assembly includes a metal case having a wall extending cylindrically about a central axis with an annular leg extending radially inwardly from the wall toward the central axis. An elastomeric material is bonded to the leg, and a PTFE seal element is attached to the elastomeric material at a bond joint. The bond joint is spaced radially inwardly from the leg and in radial alignment with the leg and inhibits the elastomeric material from flexing. As such, the elastomeric material is isolated or substantially isolated from impacting the performance of the PTFE seal element during use. Accordingly, the bond joint provides a reliable seal of the PTFE seal element against a running surface of a shaft or wear sleeve.

摘要： A flanged cover assembly includes a cover having a wall portion, a lateral attachment flange surrounding the wall portion extending outwardly therefrom and a plurality of spaced flange bores extending through the flange from a upper surface to a lower surface. The bores are adapted to receive a corresponding plurality of fasteners which are adapted to be inserted through the bores and secure the cover to a base. The invention also includes a spring retainer which is adapted to extend along at least a portion of the outer surface of the lateral attachment flange. The spring retainer has a plurality of spaced retainer bores corresponding to at least two of the spaced flange bores and at least one shaped spring portion that is adapted to contact the upper surface of the lateral attachment flange mediate the spaced flange bores. The assembly may also include a cover gasket having a plurality of bores corresponding to the plurality of spaced flange bores and spaced retainer bores. The shaped spring portion is adapted to apply a spring force to the lateral attachment flange when the fasteners are inserted through the plurality of spaced retainer bores and the plurality of spaced flange bores and used to secure the cover and the gasket to the base.
