Abstract

A compressor assembly having a housing with a number of sound control chambers. A method of controlling a sound level of a compressor assembly having a step of providing a plurality of sound control chambers. A method of controlling a sound level of a compressor assembly having a step of eliminating an operator'"'"'s line-of-sight view to noise producing components of the compressor assembly. Sound level of a compressor can be controlled by separating the internal volume of a housing which encases at least a portion of a pump assembly to create sound control chambers and/or eliminating an operator'"'"'s line-of-sight view to noise producing components of the compressor assembly.

Claims

1. A compressor assembly, comprising:

a universal motor;

a belt-driven pump assembly having a pump driven by a drive belt driven by the universal motor;

a housing configured to cover at least in part each of an air ducting shroud, a conduit and a belt-driven pump assembly;

a fan configured to provide a cooling air; and

a noise level which is 75 dBA or less when the compressor is in a compressing state;

wherein said air ducting shroud surrounds at least a portion of the universal motor and is configured to feed a first portion of said cooling air to cool at least a portion of said universal motor; and

wherein said conduit is configured to feed a second portion of said cooling air to cool at least a portion of said belt-driven pump assembly.

2. A compressor assembly according to claim 1, wherein said air ducting shroud feeds said cooling air to said conduit.

3. A compressor assembly according to claim 1, wherein said fan is driven by said universal motor.

4. The compressor assembly according to claim 1, wherein said fan is surrounded at least in part by said air ducting shroud.

5. The compressor assembly according to claim 1, wherein said fan is mounted on a motor shaft of said universal motor.

6. The compressor assembly according to claim 1, further comprising:

a shroud inlet scoop that guides cooling air from an air inlet to the fan.

7. The compressor assembly according to claim 1, further comprising:

a fan cover and a plurality of inlet ports,

wherein said fan cover and said plurality of inlet ports are configured to block a compressor assembly operator'"'"'s line-of-sight view to the fan when the compressor assembly is in a compressing state.

8. The compressor assembly according to claim 1, further comprising:

an exhaust sound control chamber configured to receive and exhaust cooling air that has passed through the air ducting shroud.

9. The compressor assembly according to claim 1, further comprising:

an exhaust sound control chamber configured to receive an exhaust cooling air that has passed through the conduit.

10. The compressor assembly according to claim 1, further comprising:

a muffler; and

wherein a feed air flows through the muffler prior to being fed to the belt-driven pump assembly.

11. A compressor assembly, comprising:

a universal motor;

a belt-driven pump assembly having a pump driven by a drive belt driven by the universal motor;

a fan configured to provide cooling air to at least a portion of each of said universal motor and said belt-driven pump assembly;

a housing that covers at least a portion of each of said motor and said belt-driven pump assembly;

a sound control chamber at least in part containing said belt-driven pump assembly, said sound control chamber contained at least in part by said housing;

a fan chamber at least in part containing said fan, said fan chamber contained at least in part by said housing; and

a noise level which is 75 dBA or less when the compressor assembly is in a compressing state.

12. A compressor assembly according to claim 11, further comprising:

an exhaust sound control chamber configured to receive a exhaust cooling air that has cooled at least one of the universal motor and belt-driven pump assembly.

13. A compressor assembly according to claim 11, further comprising:

at least one chamber having a dead air.

14. A compressor assembly according to claim 11, further comprising:

at least one sound control chamber having a trapped air space.

15. A compressor assembly according to claim 11, further comprising:

an air ducting shroud surrounding at least a portion of said universal motor.

16. A compressor assembly according to claim 11, further comprising:

a cooling air flow path guiding said cooling air through at least a portion of the fan chamber and at least a portion of a pump sound control chamber, said cooling air flow path configured to cool the universal motor and the belt-driven pump assembly.

17. A compressor assembly according to claim 11, further comprising:

an air ducting shroud at least in part present in the fan chamber and at least in part present in the pump sound control chamber.

18. A compressor assembly according to claim 11, further comprising:

a partition configured between the fan chamber and pump sound control chamber.

19. A compressor assembly according to claim 11, further comprising:

a noise absorber configured adjacent to a partition of the sound control chamber.
