Abstract: A compressor includes a shell, a first scroll member, a second scroll member and a sealing assembly. The shell defines a first pressure region and a second pressure region. The first scroll member is disposed within the shell and includes a first end plate and a first scroll wrap. The second scroll member includes a second end plate and a second scroll wrap. The second scroll wrap meshingly engages the first scroll wrap to define a compression chamber therebetween. The seal assembly fluidly separates the first and second pressure regions from each other. The seal assembly includes a first plate, a second plate, a first sealing member and a second sealing member. The first sealing member is sealingly engaged with the first plate and the second plate. The second sealing member is sealingly engaged with the first sealing member and the first plate.

Abstract: A compressor includes a shell, first and second scroll members, a fitting assembly and a valve assembly. The first scroll member includes a first end plate having a first spiral wrap extending therefrom. The second scroll member includes a second end plate having a second spiral wrap extending therefrom and an injection passage formed in the second end plate. The second spiral wrap is meshingly engaged with the first spiral wrap to form compression pockets. The injection passage is in fluid communication with the compression pockets. The fitting assembly is in fluid communication with the injection passage. The valve assembly coupled to one of the second scroll member and the fitting assembly and movable between a closed position in which fluid communication between the compression pockets and the suction chamber is prevented and an open position in which fluid communication between the compression pockets and the suction chamber is allowed.
