Claims

The claims defining the invention are as follows:

1 . A compressor valve suitable for use in a compressor between a cylinder head including a suction passage in which a fluid flow is drawn into a cylinder under low pressure and a discharge passage to which compressed air is discharged, where in the cylinder, mechanical compression of the fluid flow is carried out to generate a high pressure fluid flow, the compressor valve comprising:

a. a first body member;

b. a second body member;

c. the first body member and the second body member each defining a set of suction flow passages in fluid communication with each other between the suction passage and the cylinder, and a set of compression flow passages in fluid communication with each other between the cylinder and the discharge passage;

d. a suction seal located at least partially between the first body member and the second body member, the suction seal being configured for at least partially restricting flow through the suction flow passages;

e. a compression seal located at least partially between the first body member and second body member, the compression seal being configured for at least partially restricting flow through the compression flow passages; f. the suction seal being movable between a closed position in which the fluid flow through the suction passage is restricted, and an open position in which fluid flow through the suction passage is less restricted, the suction seal being biased to a closed position against the flow of fluid from the suction passage to the cylinder;

g. the compression seal being movable between a closed position in which the fluid flow through the compression passage is restricted, and an open position in which fluid flow through the compression passage is less restricted, the compression seal being biased to a closed position against the flow of fluid from the cylinder to the discharge passage; and

wherein the suction seal and the compression seal are biased by helical coil springs.

2. The compressor valve of claim 1 , wherein the suction seal and the compression seal are enclosed between the first body member and the second body member.

3. The compressor valve of claim 1 , wherein the suction seal and the compression seal comprise a plurality of buttons adapted to seal the suction flow passages and the set of compression flow passages.

4. The compressor valve of claim 1 , wherein the suction seals and the compression seals have chamfered edges to aid with sealing.

5. The compressor valve of claim 1 , wherein the suction seals and the compression seals are made from PEEK.

6. The compressor valve of claim 1 , wherein the suction seals and the compression seals are made from thermoset plastic.

7. The compressor valve of claim 1 , wherein the first body member and the second body member are sealed using O-rings.

8. The compressor valve of claim 7, wherein the O-rings separate the suction flow passages from the compression flow passages.

9. A compressor valve suitable for use in a compressor between a cylinder head including a suction passage in which a fluid flow is drawn into a cylinder under low pressure and a discharge passage to which compressed air is discharged, and a cylinder in which mechanical compression of the fluid flow is carried out to generate a high pressure fluid flow, the compressor valve comprising:

a. a first body member;

b. a second body member;

c. the first body member and the second body member each defining a set of suction flow passages in fluid communication with each other between the suction flow passage and the cylinder, and a set of compression flow passages in fluid communication with each other between the cylinder and the discharge passage;

d. an annular suction seal located at least partially between the first body member and the second body member, the annular suction seal being configured for at least partially restricting flow through the suction flow passages;

e. an annular compression seal located at least partially between the first body member and the second body member, the annular compression seal being configured for at least partially restricting flow through the compression flow passages;

f. the suction seal being movable between a closed position in which the fluid flow through the suction passage is restricted, and an open position in which fluid flow through the suction passage is less restricted, the annular suction seal being biased to a closed position against the flow of fluid from the suction passage to the cylinder;

g. the annular compression seal being movable between a closed position in which the fluid flow through the compression passage is restricted, and an open position in which fluid flow through the compression passage is less restricted, the compression seal being biased to a closed position against the flow of fluid from the cylinder to the discharge passage; and

wherein the annular suction seal and the annular compression seal are biased by biasing arrangements spaced at least three regular intervals around their circumference.

10. The compressor valve of claim 9, wherein the annular suction seal and the annular compression seal are enclosed between the first body member and the second body member.

11. The compressor valve of claim 9, wherein the annular suction seal comprises a plurality of buttons adapted to seal the suction flow passages and the set of compression flow passages.

12. The compressor valve of claim 9, wherein the annular suction seals and the annular compression seals have chamfered edges to aid with sealing.

13. The compressor valve of claim 9, wherein the annular suction seals and the annular compression seals are made from PEEK.

14. The compressor valve of claim 9, wherein the annular suction seals and the annular compression seals are made from thermoset plastic.

15. The compressor valve of claim 9, wherein the first body member and the second body member are sealed using O-rings.

16. The compressor valve of claim 9, wherein the O-rings separate the suction flow passages from the compression flow passages.

17. A compressor including the compressor valve of any one of the preceding claims.
