Abstract: A compressor electrical component enclosure may include a base and a lid. The base may include first and second opposing surfaces and a magnet. The magnet may be coupled to the second surface and may secure the base to a compressor shell. The lid may engage the base and cooperate with the base to define an electrical component housing.

Abstract: A compressor may include a shell, first and second scroll members, and a seal assembly. The shell defines a first and second pressure regions. The first scroll member may include a first end plate defining a chamber. The seal assembly may surround the discharge passage and fluidly separate the first and second pressure regions from each other. The seal assembly may include first and second sealing members. The first sealing member may prevent communication between the chamber and the second pressure region when a first fluid pressure within the second pressure region is higher than a second fluid pressure within the chamber. The first sealing member may define a leakage path when the first fluid pressure is lower than the second fluid pressure. The second sealing member may fluidly separate the chamber and the second pressure region when the first fluid pressure is lower than the second fluid pressure.

Abstract: A scroll compressor has a one-way drive for resisting and impeding objectionable reverse movement of the orbiting scroll member. The one-way drive includes a one-way clutch interconnecting a drive shaft with a stationary member of the compressor through a resilient member. Reverse rotation of the drive shaft causes a loading of the resilient member which then operates to cushion the stopping of the reverse rotation of the drive shaft. The one-way drive is inoperative during forward rotation of the drive shaft thus allowing normal operation of the compressor.

Abstract: A scroll type machine is disclosed which incorporates an improved mounting arrangement for the non-orbiting scroll member which mounting arrangement greatly facilitates manufacturing and assembly, effectively prevents radial displacement of the non-orbiting scroll member, and offers the advantages of axial compliance. In one embodiment, the non-orbiting scroll is axially movably secured to a bearing housing by means of a plurality of bolts or bolts and sleeves. In another embodiment a rigid annular ring serves to axially movably secure the non-orbiting scroll to the bearing housing while in a third embodiment a stamped ring is secured to both the non-orbiting scroll and the bearing housing. In another embodiment a two piece main bearing housing includes an integral ring for radially positioning the non-orbiting scroll member and means for securing anti-rotation and axial stop means thereto.

Abstract: A scroll-type machine has a motion controlling member for preventing relative rotation between a first and a second scroll member while allowing relative orbiting motion therebetween. The scroll-type machine includes a novel arrangement of a spring or other flexible member for biasing the motion controlling member in a specific direction. The biasing of the motion controlling member operates to reduce the mechanical impact noise or rattle which is caused by the vibration of the machine's operating components.

Abstract: A heat shield is disposed in a hermetic compressor between a discharge port and a local area on an interior surface of the outer shell toward which relatively hot compressed gas is directed. The local area of the outer shell is thereby insulated from the high temperature of the discharge gas.

Abstract: A scroll compressor has a fluid brake for resisting and impeding objectionable reverse movement of the orbiting scroll member. The brake includes a one-way clutch interconnecting a drive shaft and a paddle disposed in the compressor oil sump, and optionally a rotor shield for controlling oil flow around the lower end of the motor rotor. A two piece paddle has a rotatable paddle having blades to impart angular momentum to the lubricating oil and a stationary housing having vanes to resist the angular momentum imparted to the lubricating oil by the blades of the rotatable housing.
