Claim 0:
1. A compressor comprising:
a shell defining a first pressure region and a second pressure region;
a first scroll member disposed within the shell and including a first end plate and a first scroll wrap, the first end plate defining a discharge passage in communication with the first pressure region;
a second scroll member including a second end plate and a second scroll wrap, the second scroll wrap meshingly engaging the first scroll wrap to define a compression chamber therebetween; and
a seal assembly fluidly separating the first and second pressure regions from each other, wherein the seal assembly includes a first plate, a second plate, and a sealing member, wherein the first and second plates surround the discharge passage, wherein the sealing member is sealingly engaged with the first plate and the second plate to restrict fluid flow from the first pressure region to the second pressure region,
wherein the second plate includes an annular protrusion extending therefrom and sealingly engaged with an upper surface of the first plate to further restrict fluid flow from the first pressure region to the second pressure region, and
wherein the first plate includes a projection that extends through an aperture in the second plate, and wherein the annular protrusion is radially spaced apart from the projection and the aperture.
