The subject invention provides a pivot assembly for rotatably connecting a rotor to a swash plate in a variable displacement compressor. The rotor and swash plate each having pivot arms supporting pivot pins. A hinge is mounted to both of the pivot pins for operatively connecting the rotor to the swash plate. The hinge includes a first mounting portion receiving one of the pins and a second mounting portion receiving the other pin with a central planar region disposed between the first and second mounting portions. A tab extends from the central planar region toward each of the first and second mounting portions to engage the pins and fixedly secure the pins within their respective mounting portions. The pins therefore remain mounted to the hinge during an operation of the variable displacement compressor.

Hinge for a variable displacement compressor

A piston or similar cylindrical work piece is wear coated with a liquid coating material comprised of a solid component carried by a volatile solvent. The coating material is applied, from a closed reservoir, by a synchronously rotated distribution roller, to a larger diameter coating roller that is continually heated to a temperature sufficient to remove a majority of the solvent. Simultaneously, the piston workpiece is pre heated to a comparable temperature before being engaged with the coating roller under a relatively high pressure. A series of thin, pre dried layers is applied to the workpiece surface sufficient to produce the a final wear layer of a desired final thickness.
