Discharge valve for reciprocating compressor having inner and outer flow areas

1. A compressor comprising:

a compressor body; and

a discharge valve assembly coupled to the compressor body between a valve plate and a valve retainer and including at least one reed valve assembly including:

a first support guide member;

a second support guide member; and

a reed assembly; said reed assembly including a reed and a spring washer disposed between the first and second support guide members and movable between a closed position wherein the reed engages the valve plate to restrict discharge gas from entering the compressor body and an open position wherein the reed is displaced from the valve plate to permit gas to escape the compressor body through an escape area defined by an outer escape area located between an outer diameter of the reed and the valve plate and an inner escape area located between an inner diameter of the reed and the second support guide,

wherein the first support guide member includes a first central hub with a plurality of arms extending therefrom and extending a distance greater than an inner diameter of the spring washer and an inner diameter of the reed.

2. The compressor of claim 1 wherein the escape area is further defined by an upper channel area located between the reed assembly and the first support guide member.

3. The compressor of claim 2 wherein the escape area is further defined by an inner channel area located between the reed assembly and the second support guide.

4. The compressor of claim 2 wherein the reed assembly includes an upper washer that engages the first support guide in the open position.

5. The compressor of claim 4 wherein the first support guide member includes at least three first arms extending from the first central hub a distance greater than an inner diameter of the upper washer and providing an upper support for the reed assembly.

6. The compressor of claim 5 , wherein the at least three first arms includes a first pair of first arms and a second pair of first arms.

7. The compressor of claim 5 wherein the second support guide member includes a second central hub and at least three second arms extending therefrom to a distance less than the inner diameter of the reed.

8. The compressor of claim 7 , wherein the at least three second arms includes a first pair of second arms and a second pair of second arms.

9. The compressor of claim 1 wherein the valve plate includes a conical flow boundary surface.

10. The compressor of claim 1 , wherein the second support guide member includes a flange extending radially outwardly a distance greater than the inner diameter of the reed, wherein the reed assembly engages the flange while in the closed position.

11. A compressor comprising:

a compressor body; and

a discharge valve assembly coupled to the compressor body and configured to direct discharge gas from the compressor body and between a valve plate and a valve retainer, the discharge valve assembly comprising at least one reed valve assembly comprising:

a first support guide member;

a second support guide member; and

a reed assembly including a reed and a spring washer disposed between the first and second support guide members and movable between a closed position wherein the reed engages the valve plate to restrict discharge gas from entering the compressor body and an open position wherein the reed is displaced from the valve plate and permits gas to escape the compressor body through an escape area defined by an outer escape area, an inner escape area, an upper channel area and an inner channel area, wherein the outer escape area is located between the reed and the valve plate, the inner escape area is located between the reed and the second support guide, the upper channel area is located between the reed assembly and the first support guide member and the inner channel area is located between the reed assembly and the second support guide,

wherein the first support guide member includes a first central hub with a plurality of arms extending therefrom and extending a distance greater than an inner diameter of the spring washer and an inner diameter of the reed.

12. The compressor of claim 11 wherein the reed assembly further includes an upper washer that engages the first support guide in the open position.

13. The compressor of claim 12 wherein the first support guide member includes at least three first arms extending from the first central hub a distance greater than an inner diameter of the upper washer and provide an upper support for the reed assembly.

14. The compressor of claim 13 , wherein the at least three first arms includes a first pair of first arms and a second pair of first arms.

15. The compressor of claim 14 wherein the second support guide member comprises a second central hub and at least three second arms extending therefrom and extending a distance less than an inner diameter of the reed.

16. The compressor of claim 15 , wherein the at least three second arms includes a first pair of second arms and a second pair of second arms.

17. The compressor of claim 16 wherein the at least three first arms are radially aligned with the at least three second arms.

18. The compressor of claim 17 wherein the at least three first arms extend radially outwardly a first distance and the at least three second arms extend radially outwardly a second distance and wherein the first distance is greater than the second distance.

19. The compressor of claim 11 , further comprising a bolt centrally extending through the reed valve assembly and threadably mating with the second support guide member.

20. The compressor of claim 11 , wherein the second support guide member includes a flange extending radially outwardly a distance greater than the inner diameter of the reed, wherein the reed assembly engages the flange while in the closed position.
