A dual chamber discharge muffler for a compressor. The dual chambers of the discharge muffler are separated by a check valve that closes upon shutdown of the compressor, which in turn limits the amount of exhaust gases in the discharge muffler that are able to return to the compressor. The dual chambers are formed by dividing a muffler housing with a dividing plate. The dividing plate may also be adapted to receive a fastener that through mounts the muffler to the compressor.

Dual chamber discharge muffler

A muffler that is externally mounted to a housing shell of a compressor. To externally mount the muffler to the housing shell and prevent unnecessary vibration of the muffler during compressor operation, an attachment device connects an essentially central portion of the muffler to the housing shell. The attachment device may also be adapted to house a pressure- or temperature-related sensor device.

Compressor with discharge muffler attachment using a spacer

A scroll component including a spiral scroll wrap, a baseplate having a first major surface coupled to the scroll wrap and a second opposing major surface comprising a protruding pilot extending a distance from the baseplate, and a hub fastened to the baseplate adjacent to the protruding pilot. A method of forming a scroll compressor element is also provided.

Powder metal scroll hub joint

A compressor may include a housing, a compression mechanism supported within the housing, and a seal assembly. The housing may include a suction pressure region and a first discharge passage in communication with a discharge pressure region. The compression mechanism may include a second discharge passage in communication with the first discharge passage. The seal assembly may be sealingly engaged with the housing and the compression mechanism to define a chamber and to provide sealed communication between the first and second discharge passages. The seal assembly may include a seal member engaged with the compression mechanism and including a leg having an opening therein. The leg may isolate the chamber from the discharge pressure region when in a first position and may provide communication between the chamber and the discharge pressure region through the opening when in a second position different than the first position.

Scroll machine with seal

A scroll machine includes a shell and a pair of scroll members. At least one of the scroll members disposed in the shell is mounted for axial movement with respect to the other scroll member disposed in the scroll. The amount of axial movement of at least one scroll member is accurately controlled by providing a stop. The stop is defined by the contact of the end plate of the at least one scroll member with another member of the scroll machine which is accurately positioned within the shell of the scroll machine. The member can be either the shell or another component which engages the shell.

Flanged sleeve guide

A scroll machine utilizes a floating seal to isolate pressurized fluid to provide axial biasing. The floating seal is designed as a single piece plate with inner and outer annular seals. The inner and outer annular seals can be U-shaped, V-shaped or L-shaped and each configuration is oriented to provide pressure actuation of the seal. Additional embodiments add a discharge valve, a high temperature protection system or a high pressure protection system to the floating seal.
