Compressor with compliant seal

1. A compressor comprising:

a shell defining a discharge chamber and a suction chamber;

a first scroll member disposed within the shell and including a first end plate and a first spiral wrap extending from the first end plate;

a second scroll member disposed within the shell and including a second end plate and a second spiral wrap extending from the second end plate and meshingly engaged with the first spiral wrap;

a floating seal sealingly engaging the second scroll member;

a muffler plate defining the discharge chamber and the suction chamber; and

a wear ring sealingly engaging the muffler plate and the floating seal such that the wear ring, the muffler plate, and the floating seal fluidly isolate the discharge chamber from the suction chamber,

wherein the muffler plate includes an axially facing surface that contacts the wear ring, wherein the axially facing surface includes an annular recess formed therein, and wherein the wear ring at least partially covers the annular recess, and the annular recess provides clearance between the muffler plate and the wear ring to allow the wear ring to resiliently deflect relative to the muffler plate during operation of the compressor, and

wherein the floating seal contacts a radially intermediate portion of the wear ring that is disposed radially between a radially innermost edge of the annular recess and a radially outermost edge of the annular recess.

2. The compressor of claim 1 , wherein the wear ring extends radially across the entire annular recess such that the axially facing surface contacts the wear ring at a first location disposed radially inward relative to the annular recess and at a second location disposed radially outward relative to the annular recess.

3. The compressor of claim 2 , wherein radially inner and radially outer portions of the wear ring are formed from a first material, and wherein the radially intermediate portion of the wear ring is formed from a second material that is more flexible than the first material.

4. The compressor of claim 3 , wherein the wear ring includes an annular recess defined by the radially intermediate portion of the wear ring.

5. The compressor of claim 1 , wherein the axially facing surface of the muffler plate contacts the wear ring at a location disposed radially outward relative to the annular recess, and wherein a radially central portion of the wear ring and a radially inner portion of the wear ring are aligned with the annular recess such that the radially central and radially inner portions of the wear ring are unsupported by the muffler plate.

6. The compressor of claim 1 , wherein the axially facing surface of the muffler plate contacts the wear ring at a location disposed radially inward relative to the annular recess, and wherein a radially central portion of the wear ring and a radially outer portion of the wear ring are aligned with the annular recess such that the radially central and radially outer portions of the wear ring are unsupported by the muffler plate.

7. The compressor of claim 1 , wherein the wear ring includes an annular recess defined by the radially intermediate portion of the wear ring.

8. The compressor of claim 7 , wherein the annular recess in the wear ring is formed in a first side of the wear ring opposite a second side of the wear ring, and wherein the floating seal contacts the second side of the wear ring.

9. The compressor of claim 8 , wherein the radially intermediate portion of the wear ring is formed from the same material as radially inner and radially outer portions of the wear ring.

10. The compressor of claim 1 , wherein the radially intermediate portion of the wear ring is thinner than radially inner and radially outer portions of the wear ring.

11. A compressor comprising:

a shell defining a discharge chamber and a suction chamber;

a first scroll member disposed within the shell and including a first end plate and a first spiral wrap extending from the first end plate;

a second scroll member disposed within the shell and including a second end plate and a second spiral wrap extending from the second end plate and meshingly engaged with the first spiral wrap;

a floating seal sealingly engaging the second scroll member;

a muffler plate defining the discharge chamber and the suction chamber; and

a wear ring sealingly engaging the muffler plate and the floating seal such that the wear ring, the muffler plate, and the floating seal fluidly isolate the discharge chamber from the suction chamber,

wherein the muffler plate includes an axially facing surface that contacts the wear ring, wherein radially inner and radially outer portions of the wear ring are formed from a first material, and wherein a radially intermediate portion of the wear ring is formed from a second material that is different from the first material.

12. A compressor comprising:

a shell defining a discharge chamber and a suction chamber;

a first scroll member disposed within the shell and including a first end plate and a first spiral wrap extending from the first end plate;

a second scroll member disposed within the shell and including a second end plate and a second spiral wrap extending from the second end plate and meshingly engaged with the first spiral wrap;

a floating seal sealingly engaging the second scroll member;

a muffler plate defining the discharge chamber and the suction chamber; and

a wear ring sealingly engaging the muffler plate and the floating seal such that the wear ring, the muffler plate, and the floating seal fluidly isolate the discharge chamber from the suction chamber,

wherein the muffler plate includes an axially facing surface that contacts the wear ring, wherein a radially intermediate portion of the wear ring defines an annular recess in the wear ring,

wherein the annular recess in the wear ring is formed in a first side of the wear ring opposite a second side of the wear ring, and wherein the floating seal contacts the second side of the wear ring.

13. The compressor of claim 12 , wherein the floating seal contacts the radially intermediate portion of the wear ring.

14. The compressor of claim 12 , wherein radially inner and radially outer portions of the wear ring are formed from a first material, and wherein the radially intermediate portion of the wear ring is formed from a second material that is different from the first material.

15. The compressor of claim 14 , wherein the second material is more flexible than the first material.

16. The compressor of claim 12 , wherein the radially intermediate portion of the wear ring is thinner than radially inner and radially outer portions of the wear ring.

17. The compressor of claim 12 , wherein the axially facing surface of the muffler plate defines another annular recess that is at least partially radially aligned with the annular recess in the wear ring.

18. The compressor of claim 17 , wherein the wear ring extends radially across the entire annular recess in the muffler plate such that the axially facing surface contacts the wear ring at a first location disposed radially inward relative to the annular recesses of the muffler plate and the wear ring and at a second location disposed radially outward relative to the annular recesses of the muffler plate and the wear ring.
