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

a fan cooling at least a portion of the pump assembly;

a housing encasing at least a portion of the pump assembly and at least a portion of the fan; and

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

2. The compressor assembly according to claim 1, wherein the housing further comprises a plurality of partitions.

3. The compressor assembly according to claim 1, wherein the housing further comprises at least two partitions.

4. The compressor assembly according to claim 1, wherein the housing further comprises at least three partitions.

5. The compressor assembly according to claim 1, wherein the housing further comprises a plurality of sound control chambers.

6. The compressor assembly according to claim 1, wherein the housing further comprises a fan sound control chamber.

7. The compressor assembly according to claim 1, wherein the housing further comprises a pump sound control chamber.

8. The compressor assembly according to claim 1, wherein the housing further comprises an exhaust sound control chamber.

9. The compressor assembly according to claim 1, wherein the housing further comprises an upper sound control chamber.

10. The compressor assembly according to claim 1, wherein the housing further comprises a fan sound control chamber having inlet ports through which an operator'"'"'s line-of-sight view to the fan is eliminated at least in part by an air space cover.

11. The compressor assembly according to claim 1, wherein the housing further comprises a fan sound control chamber having inlet ports through which an operator'"'"'s line-of-sight view to the fan is eliminated at least in part by an air space cover and at least in part by a portion of an air ducting shroud.

12. A method for controlling a sound level of a compressor assembly, comprising the steps of:

providing a universal motor;

providing a pump assembly having a pump driven by a drive belt;

driving the drive belt by the universal motor;

providing a plurality of sound control chambers; and

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

13. The method for controlling a sound level of a compressor assembly according to claim 12, further comprising the step of:

eliminating an operator'"'"'s line-of-sight view to the pump assembly.

14. The method for controlling a sound level of a compressor assembly according to claim 12, further comprising the step of:

dampening a vibration of a compressed gas tank.

15. The method for controlling a sound level of a compressor assembly according to claim 12, further comprising the step of:

feeding cooling air to a fan by a sinusoidal feed path.

16. The method for controlling a sound level of a compressor assembly according to claim 12, further comprising the step of:

absorbing sound in a plurality of dead air spaces.

17. A means for controlling a sound level of a compressor assembly, comprising:

a universal motor;

a pump assembly having a pump driven by a drive belt;

the universal motor configured to drive the drive belt;

a means for controlling a sound generated by the compressor assembly;

a means for controlling the sound level of a compressor assembly to a value of 75 dBA or less when the compressor is in a compressing state.

18. The means for controlling a sound level of a compressor assembly according to claim 17, further comprising a means for separating the internal volume of a housing which encases at least a portion of a pump assembly to create sound control chambers.

19. The means for controlling a sound level of a compressor assembly according to claim 17, further comprising a means for eliminating an operator'"'"'s line-of-sight view to the fan from outside of the compressor assembly.

20. The means for controlling a sound level of a compressor assembly according to claim 17, further comprising a means creating a dead air space within a housing which encases at least a portion of a pump assembly to create sound control chambers.
