Compressor High-Side Axial Seal And Seal Assembly Retainer

摘要

A compressor may include a non-orbiting scroll, an orbiting scroll, a drive shaft, a bearing housing and an annular seal. The non-orbiting scroll includes a first spiral wrap. The orbiting scroll includes an end plate having a second spiral wrap ending from a first side of the end plate and an annular hub extending from a second side of the end plate. The first and second spiral wraps cooperate to compress working fluid from a suction pressure to a discharge pressure. The drive shaft includes a crankpin received in the hub and drives the orbiting scroll. The bearing housing rotatably supports the drive shaft and may define a biasing chamber containing working fluid biasing the orbiting scroll toward the non-orbiting scroll in an axial direction. The annular seal may engage a diametrical surface of the hub and engage the bearing housing, thereby defining the biasing chamber.

1. A compressor comprising:
a non-orbiting scroll including a first spiral wrap; an orbiting scroll including an end plate having a second spiral wrap ending from a first side of said end plate and an annular hub extending from a second side of said end plate, said first and second spiral wraps cooperating to compress working fluid from a suction pressure to a discharge pressure; a drive shaft having a crankpin received in said hub and driving said orbiting scroll in an orbital path relative to said non-orbiting scroll; a bearing housing rotatably supporting said drive shaft and defining a biasing chamber containing working fluid biasing said orbiting scroll toward said non-orbiting scroll in an axial direction; and a first annular seal engaging a diametrical surface of said hub and engaging said bearing housing, thereby defining said biasing chamber.
