Abstract: A hermetic compressor including a hermetically sealed housing having a first housing shell and a second housing shell, a compressor unit disposed in the housing, a motor having a stator and a rotor, the rotor rotatably connected to a crankshaft drivingly connected to the compressor unit, a welding flange connected to the first and second housing shells to provide a hermetically sealed housing assembly, and an acoustic insulator interposed between the compressor unit and the welding flange, the acoustic insulator made from a vibration absorbing material, whereby the insulator reduces the communication of vibrations from the compressor unit to the housing during compressor operation.

Abstract: A compressor assembly includes a compressor mechanism mounted within a hermetically sealed housing. The housing is effectively divided into a low pressure area at a relatively low temperature and a high pressure area at a relatively high temperature. A motor and a lubrication system are contained within the low pressure area and the discharge side of the compressor mechanism is disposed in the high pressure area. A cylinder block effectively separates the high and low pressure areas of the compressor. The lubrication system includes an axial passage for communication oil from a sump to various compressor components, including rotational bearings. A seal cap is disposed at the end of the crankshaft that extends into the high pressure area and in combination with the cylinder block defines an oil discharge chamber at low pressure and isolated from the high pressure area.

Abstract: A compressor having an oil pick-up tube which filters incoming lubricant, and increases the volumetric pumping capacity of the compressor. The oil pick-up tube is attached to the crankshaft of the compressor, and is partially disposed within an oil sump also provided in the compressor. When the motor of the compressor is energized, the crankshaft and the oil pick-up tube rotate, and oil from the oil sump is drawn into the oil pick-up tube. A passageway is provided within the motor shaft to communicate oil from the oil pick-up tube to the compressor mechanism of the compressor for lubrication purposes. A cylindrical screen is also provided within the oil pick-up tube to both filter the incoming oil and provide a surface to which the oil adheres as it migrates upward through the rotating tube and expels the oil radially outward to increase the velocity of the migrating oil. The volumetric pumping capacity of the compressor is thereby increased.

Abstract: A compressor assembly is disclosed including a compressor mechanism mounted within a hermetically sealed housing. A cylinder block assembly, containing a plurality of reciprocating pistons within compression chambers, is covered by cylinder heads. The compression chambers include a discharge valve which permits compressed refrigerant to empty into a common discharge chamber. A pressure relief mechanism, formed by cylinder heads yieldably attached to the crankcase, is included within the compressor to eliminate damage caused by high pressure conditions such as slugging. Alternatively, pressure relief may be created in the common discharge chamber by a yieldably attached cage bearing or a valved port.

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.

Abstract: A protective cap for the hermetic terminal of a hermetic compressor includes a cup-shaped plastic member for attaching to and covering the hermetic terminal during manufacturing, shipping, and storage of the compressor, i.e., whenever the hermetic terminal would not otherwise be connected to an external source of power. The cap contactingly engages the base portion and conducting pins of the hermetic terminal. The protective cap includes a cylindrical stud portion arranged coaxially within an outer cylindrical wall portion of the cup-shaped member. The stud portion slip fits radially inwardly of the circularly arranged conductor pins of the hermetic terminal. A tapered end facilitates guided insertion of the stud portion within the conductor pins prior to engagement of the cap with the hermetic terminal base portion.
