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.

First claim

We claim:

1. A compressor assembly, comprising:
a pump assembly;
a fan;
a housing encasing at least a portion of the pump assembly and at least a portion of the fan, the housing having a fan sound control chamber having radially arranged intake ports through an air space cover attached thereto; and
a noise level which is 75 dBA or less when the compressor is in a compressing state,
wherein an operator's line-of-sight view to the fan is eliminated at least in part by the air space cover.

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 pump sound control chamber.

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

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

9. The compressor assembly according to claim 1 , wherein the housing further comprises an air ducting shroud wherein an operator's line-of-sight view to the fan is eliminated at least in part by the air space cover and at least in part by a portion of the air ducting shroud.

10. A method for controlling a sound level of a compressor assembly, comprising the steps of:
providing a housing having exhaust vents therethrough and a plurality of sound control chambers,
providing a pump assembly arranged between a fan inlet and the exhaust vents;
partitioning at least one of the plurality of sound control chambers to eliminate an operator's line of sight view through the exhaust vents to the pump assembly; and
operating the compressor assembly at a noise level which is 75 dBA or less when the compressor is in a compressing state.

11. The method for controlling a sound level of a compressor assembly according to claim 10 , further comprising the step of:
dampening a vibration of a compressed gas tank.

12. The method for controlling a sound level of a compressor assembly according to claim 10 , further comprising the step of:
feeding cooling air to a fan by a sinusoidal feed path.

13. The method for controlling a sound level of a compressor assembly according to claim 10 , further comprising the step of:
absorbing sound in a plurality of dead air spaces.

14. A means for controlling a sound level of a compressor assembly, comprising:
a means for controlling a sound generated by said compressor assembly including a pump and a fan,
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, and
means for creating a dead air space within a housing which encases at least a portion of a pump assembly and creates sound control chambers arranged orthogonal to each other around an air ducting shroud.

15. The means for controlling a sound level of a compressor assembly according to claim 14 , 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.

16. The means for controlling a sound level of a compressor assembly according to claim 14 , further comprising a means for eliminating an operator's line-of-sight view to the fan from outside of the compressor assembly.
