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.
