Abstract: A hermetic compressor assembly is disclosed including a compressor mechanism and an electric drive motor within a hermetically sealed housing. The electric motor includes a rotatable rotor and a stator. In one disclosed embodiment, the stator is friction fit within the housing and a rotor is press fit over a crankshaft journalled in a crankcase of the compressor mechanism. The crankcase is selectively positioned within the housing and mounted thereto by means of mounting pins. In another disclosed embodiment, the motor is mounted to the compressor mechanism and the compressor crankcase is axially supported in the housing. A mounting pin 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 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: A cylinder block for a multi-cylinder hydraulic or hydrostatic piston device is provided having a control layer comprising a sintered friction metal layer sintered onto the cylinder block under the simultaneous action of pressure and heat. The end surface of the cylinder block is first provided with an electrodeposited metal layer. The electrodeposited layer has a crystal lattice constant compatible with the sintered layer and the material of the cylinder block. The cylinder block is preferably made from steel or aluminum and the electrodeposited layer is preferably copper or nickel. After the friction metal layer, preferably bronze, is sintered onto the electrodeposited layer, the cylinder block is treated to improve the strength and wear characteristics of the cylinder block without injuring the sliding friction characteristics of the sintered friction metal layer. In the case of steel, the preferred treating process is gas nitriding, and in the case of aluminum or an aluminum alloy, the preferred treating process is anodizing.

Abstract: An air compressor utilizing one or more pistons reciprocating within water cooled cylinders and operating in an oil free environment. Each piston is reciprocated by rotation of motor driven, balanced rotors, through a reciprocating and oscillating shuttle member. A centrally sleeved, hollow ball, accommodates shuttle member movement, while interconnecting the shuttle member and the rotors. Positive lubrication is provided for the rotor bearings, the hollow ball and shuttle member and the reciprocating piston shafts. The rotors are driven in opposite directions by motors mounted to maintain constant torque on the rotors.

Abstract: A double acting piston pump for cryogenic mediums is disclosed. The pump includes a vertically positioned cylinder having a base portion and a cover portion, and inlet valves are disposed in the cover portion and the base portion for admitting the cryogenic medium into the cylinder and for providing a pressure component of approximately zero against the direction of flow of the cryogenic medium. Outlet valves are disposed in the cover portion and the base portion for discharging the cryogenic medium from the cylinder. A piston is slideably mounted in the cylinder and a drive rod connected to the piston extends through either the cover portion or the base portion of the cylinder. A drive arrangement engages the drive rod for actuating the piston. A housing is also provided which has a portion defining the cylinder. The drive rod and the drive arrangement are mounted in the remaining portion of the housing, whereby the housing is common to the piston, the drive rod and the drive arrangement. The pump is suitable for both liquid and gaseous mediums and generates practically no frictional forces.

Abstract: The disclosure concerns cylinder barrels for piston pumps and motors which have lined cylinder bores. Each liner comprises a matrix of sintered, powdered iron which is impregnated with bronze, and which is metallurgically and mechanically bonded to the steel barrel. The liners are formed from porous, sintered iron sleeves which are placed in the bores in contact with bronze slugs. The assembly is heated in a non-oxidizing atmosphere to a temperature between 1,900*F and 2,000*F to melt the bronze and cause it to infiltrate the sintered preform and bond to the steel. Thereafter, the assembly is cooled in the non-oxidizing atmosphere to solidify the bronze, followed by air cooling to room temperature. Finally, the finished cylinder bores are machined in the bonded bronze-iron sleeves.
