Abstract: A sliding member of an iron-based non-porous material, such as vane, of a rotary compressor has a sliding surface processed by a surface treatment in which the surface is subjected to oxidizing and nitriding to form an oxidized and nitrided layer thereon. The surface is then subjected to a steam-treatment in which water is caused to react with components of the oxidized and nitrided layer to form a layer of oxidized iron of a porous network structure disposed outwardly of the oxidized and nitrided layer. The oxidized iron layer is composed mainly of tri-iron tetroxide and softer than the oxidized and nitrided layer.

Abstract: A rotary abutment type hydraulic motor is disclosed comprising a housing having a rotor chamber and a pair of abutment valve chambers intersecting the rotor chamber. A rotor having at least three lobes is disposed in the rotor chamber, and a two lobed stator is provided in each of the abutment valve chambers. The abutment valve axes are circumferentially spaced apart one-half the angular spacing between adjacent rotor lobes. A unique sealing arrangement is provided between the rotor lobes and rotor chamber wherein sealing pins carried by the rotor lobes are hydraulically displaced radially outwardly to sealingly engage the inner surface of the rotor chamber during motor operation. A unique abutment valve lobe rotor hub sealing arrangement is also provided which is defined by a metal plate extending between adjacent rotor lobes and hydraulically displaceable metal pins disposed beneath the plate in recesses in the rotor hub. Hydraulic fluid under pressure biases the pins outwardly against the plate to bias the plate into sealing engagement with the abutment valve lobes during interengagement therebetween. Opposite ends of the abutment valve shafts are provided with a floating bearing and seal arrangement which is responsive to hydraulic fluid under pressure to seal the shaft ends against leakage of hydraulic fluid thereacross.

Abstract: An improved rotor and gear assembly for rotary mechanisms of the trochoidal type, in which a rotor having a central bore is mounted for rotation on a shaft, with a bearing between the rotor bore and the journal portion of the shaft. An internally toothed ring gear is secured to a side face of the rotor for engagement with a stationary spur gear to maintain phasing between the rotor and its trochoidal housing during the planetary and rotary motion of the rotor within the housing. The ring gear is mounted on the rotor in such a manner as to maintain concentricity therewith while permitting differences in thermal expansion between the materials of the rotor and the gear, and without imposing stress on the mounting means or the bearing without causing distortion in the gear or the rotor.
