Abstract: An insert component for a scroll compressor comprises a polymer and at least one reinforcing or lubricating particle. The insert component comprises an annular body and an axial projection. The annular body defines a first centrally-disposed opening having has a central axis extending therethrough. The annular body has a first side comprising a first contact surface configured to engage a partition plate and a second side a second contact surface configured to engage a floating seal assembly. The first contact surface defines a slope between first and second radial locations. The axial projection extends from the annular body and can be received in a second centrally-disposed opening of the partition plate. The insert component can fluidly seal both a first interface between the first contact surface and the partition plate and a second interface between the second contact surface and a floating seal assembly during operation of the scroll compressor.

Abstract: A compressor may include first and second scrolls and a seal. The first scroll includes a first end plate and a first spiral wrap extending from the first end plate. The first end plate may define a discharge passage and an annular recess surrounding the discharge passage. The second scroll includes a second end plate and a second spiral wrap extending from the second end plate. The first and second spiral wraps cooperate to define a plurality of fluid pockets. The seal may be at least partially received in the annular recess and may cooperate with the first scroll to define a biasing chamber receiving fluid at an intermediate pressure. The seal may include inner and outer diametrical surfaces. The inner diametrical surface may include a plurality of first annular grooves. The outer diametrical surface may include a plurality of second annular grooves.
