    Abstract: A hermetic compressor assembly is disclosed including a compressor mechanism and an electric drive motor within a hermetically sealed housing (310). The electric motor (320) includes a rotatable rotor and a stator. In one disclosed embodiment, the stator is friction fit within the housing and the rotor is press fit over a crankshaft (330) journalled in a crankcase of the compressor mechanism. The crankcase is selectively positioned within the housing and mounted thereto by means of mounting pins (418). In another disclosed embodiment, the motor (22) is mounted to the compressor mechanism and the compressor crankcase is axially supported in the housing. A mounting pin (254) is used to prevent rotation of the compressor mechanism within the housing caused by torque forces produced by dynamic operation of the motor. The disclosed mounting pins are received within holes in the crankcase and extend radially outwardly through oversized apertures (256) in the housing. The pins are selectively positioned in the apertures prior to welding. A method of assembling a compressor having mounting pins is also disclosed.

    Abstract: In a piston (2) and cylinder (1) air compressor particularly a compressor designed to run without oil lubrication of the cylinder walls, the cylinder (1) is formed of aluminium and the piston (2) is provided with ferrous core members (6)(8) carrying P.T.F.E. bearing members (12)(13) whereby the relatively lower thermal expansion of the core (6)(8) members in relation to the cylinder (1) tends to compensate for the higher thermal expansion of the P.T.F.E.

    Abstract: The method of contemporaneously sealing interfaces of bearing surfaces for valve faces and cylinder linings in a steel rotary cylindrical barrel having a plurality of longitudinal bores extending through the barrel longitudinally from one end to the other, each of the bores having a restricted diameter intermediate portion connecting a valve surface area at one end of the barrel with a cylinder area extending to the other end. An insert of bearing material is placed in both ends of the bore and a cap secured over a lower end adjoining the cylinder bore. A removeable carbon hot top is placed over the other end of the barrel. The barrel and its assembly is heated in a metalurical furnace for 90 minutes at 1925 °F, disposed vertically, with the cap at the bottom and is then removed from the furnace and cooled with the cap resting on a bronze pedestal to cause the bearing material to slowly solidify from the bottom up, and to cause gases to rise through the restricted area of the bore as the barrel cools. When the temperature is below 1000 °F, the hot top is removed to permit solidification of the bearing material in the upper valve area.
    REFERENCE TO PRIOR CASES
