Abstract

A compressor assembly having a high velocity muffler system which produces a particle-free compressor pump feed while reducing noise output from the compressor assembly during compressing operations. The high velocity muffler system is maintenance-free and comprises an inertia filter. The compressor assembly uses a method for producing a compressor pump feed and reducing noise during compressing operations by processing a gas through the high velocity muffler system which has an inertia filter and a muffler chamber to produce a compressor pump feed which can be compressed by a pump assembly.

First claim

We claim:

1. A compressor assembly, comprising:
an inertia filter configured to filter a gas;
a muffler chamber;
an at least one of an air intake hose and a cylinder head feed hose; and
a pump assembly having a cylinder head,
wherein the gas is fed to the muffler chamber, and
wherein the gas flows through the at least one of an air intake hose and a cylinder head feed hose upstream of the cylinder head.

2. The compressor assembly according to claim 1 , wherein the gas is an air.

3. The compressor assembly according to claim 1 , wherein the inertia filter is a T-inertia filter.

4. The compressor assembly according to claim 1 , wherein the inertia filter is a stepped inertia filter.

5. The compressor assembly according to claim 1 , wherein the inertia filter is a recessed inertia filter.

6. The compressor assembly according to claim 1 , wherein the muffler chamber is free of a filter medium.

7. The compressor assembly according to claim 1 , wherein the inertia filter has a counterflow feed.

8. The compressor assembly according to claim 1 , wherein the air intake hose is configured between the inertia filter and the muffler chamber.

9. The compressor assembly according to claim 1 , wherein the cylinder head feed hose is configured between the muffler chamber and the cylinder head.

10. A compressor assembly according to claim 1 , wherein the air intake hose is configured between the inertia filter and the muffler chamber, and
wherein the cylinder head feed hose is configured between the muffler chamber and the cylinder head.

11. The compressor assembly according to claim 1 , further comprising:
wherein the muffler chamber is affixed to a support member,
wherein the air intake hose is configured between the inertia filter and the muffler chamber free of attachment to the support member, and
wherein the cylinder head feed hose is configured between the muffler chamber and the cylinder head free of attachment to the support member.

12. The compressor assembly according to claim 1 , further comprising:
a feed air port which is configured to feed the gas to the air intake hose.

13. The compressor assembly according to claim 1 , further comprising:
an intake muffler feed line which is fed the gas through the air intake hose.

14. The compressor assembly according to claim 1 , further comprising:
a feed air port which is configured to feed the gas to the air intake hose; and
an intake muffler feed line which is fed the gas through the air intake hose.

15. The compressor assembly according to claim 1 , further comprising:
a feed air port; and
an intake muffler feed line,
wherein the air intake hose provides a flow path for the gas flowing through the feed air port to flow to the intake muffler feed line.

16. The compressor assembly according to claim 1 , further comprising:
a scoop inlet;
a feed air port;
an inlet centerline; and
a filter distance from the scoop inlet to the inlet centerline in a range of 0.5 in to 6.0 in.

17. A method for producing a compressor pump feed, comprising the steps of:
providing a compressor pump assembly having an inertia filter, a muffler, and a compressor pump;
providing an at least one of an air intake hose and a cylinder head feed hose;
filtering a gas by inertia filtering;
flowing the gas through the at least one of an air intake hose and a cylinder head feed hose;
feeding the gas to the muffler; and
feeding the gas to the compressor pump.

18. A compressor assembly, comprising:
an inertia filter configured to feed a gas to an intake muffler;
a pump assembly fed the gas downstream of the intake muffler;
a motor driving the pump assembly;
a fan configured to produce a cooling air stream flowrate in a range 50 SCFM to 100 SCFM and configured to cool at least a portion of the pump assembly;
a pump assembly configured to produce 2.0 SCFM to 3.5 SCFM of a compressed gas at a pressure in a range of 25 PSIG to 250 PSIG; and
a compressor assembly weight in a range of 10 lbs to 40 lbs.

19. The compressor assembly according to 18 , wherein the motor has a horsepower rating in the range of 0.5 horsepower to 1.0 horsepower.

20. The compressor assembly according to 18 , further comprising:
a heat transfer in a range of 25 BTU/min to 200 BTU/min from the compressor assembly to the cooling air stream when the compressor assembly is in a compressing state.

21. A compressor assembly, comprising:
an air intake hose configured to feed an air to a pump assembly;
a motor driving the pump assembly;
a fan configured to produce a cooling fan flowrate in a range 50 SCFM to 100 SCFM and configured to cool at least a portion of the pump assembly;
a pump assembly configured to produce 2.0 SCFM to 3.5 SCFM of a compressed gas at a pressure in a range of 25 PSIG to 250 PSIG; and
a compressor assembly weight in a range of 10 lbs to 40 lbs.

22. A compressor assembly, comprising:
a feed fan configured to produce a flow of an air which is output by the fan;
an air intake hose;
a pump assembly configured to receive a feed of the air which has flowed through the air intake hose;
a motor driving the pump assembly,
wherein the fan is configured to produce a cooling fan flowrate in a range 50 SCFM to 100 SCFM and configured to cool at least a portion of the pump assembly;
wherein the pump assembly is configured to produce 2.0 SCFM to 3.5 SCFM of a compressed gas at a pressure in a range of 25 PSIG to 250 PSIG; and
wherein the compressor assembly has a weight in a range of 10 lbs to 40 lbs.
