Abstract

A dual gauge assembly. In an exemplary embodiment, the dual gauge assembly includes a housing. Further, a display face is disposed within the housing for displaying a pressure range. In addition, an indicating device is disposed within the housing for indicating pressure for at least two different pressure sources. Moreover, at least two ports are coupled to the housing for pneumatically coupling the at least two different pressure sources to the indicator assembly. The indicating device provides a visual indication of the at least two different pressure sources within the single housing.

Claims

1. A dual gauge assembly, comprising:

a housing;

a display face disposed within the housing for displaying a pressure range;

an indicating device disposed within the housing for indicating pressure for at least two different pressure sources; and

at least two ports coupled to the housing for pneumatically coupling the at least two different pressure sources to the indicator assembly,

wherein the indicating device provides a visual indication of the at least two different pressure sources within the housing.

2. The dual gauge assembly of claim 1, wherein the pressure range includes a first pressure range corresponding to a first pressure source and a second pressure range corresponding to a second pressure source.

3. The dual gauge assembly of claim 1, wherein the indicating device includes a first indicator indicating pressure of material disposed within a first pressure source and a second indicator indicating pressure of material disposed within a second pressure source.

4. The dual gauge assembly of claim 1, wherein the at least two ports include a first port for supplying air to a first pressure range from a first pressure source and a second port for supplying air to a second pressure range from a second pressure source.

5. The dual gauge assembly of claim 4, wherein the first port and the second port are coaxial.

6. A dual gauge assembly, comprising:

a single housing including a first port and a second port, the first port pneumatically coupled to a first pressure source and the second port pneumatically coupled to a second pressure source;

a display face disposed within the single housing for displaying a first range and a second range, the first range corresponding to the first pressure source and the second range corresponding to the second pressure source;

a first indicator disposed within the single housing operable for providing a visual indication of the pressure of material disposed within the first pressure source; and

a second indicator disposed within the single housing operable for providing a visual indication of the pressure of material disposed within the second pressure source,

wherein the first and second indicators provide a visual indication of the pressure of the material disposed within the first pressure source and the pressure of the material within the second pressure source within the single housing.

7. The dual gauge assembly of claim 6, wherein the first port and the second port are coaxial.

8. The dual gauge assembly of claim 6, wherein the first indicator indicates the pressure of material disposed within a tank and the second indicator indicates the pressure of material disposed within a regulated outlet.

9. The dual gauge assembly of claim 6, further comprising an O-ring configured for pneumatically isolating the first port from the second port.

10. The dual gauge assembly of claim 6, wherein the housing includes a threaded shaft in which the first port and second port are disposed.

11. The dual gauge assembly of claim 6, wherein the first indicator and the second indicator rotate in a single direction.

12. An air compressor including a dual gauge assembly, comprising:

a pump for pressurizing air;

a tank coupled to the pump for storing pressurized air;

a dual gauge assembly operationally coupled with the tank and a regulated outlet for providing a visual indication of a first pressure of material disposed within the tank and a second pressure of material disposed within the regulated outlet, the dual gauge assembly including;

a housing for encompassing the dual gauge assembly, the housing coupled to a first port and a second port;

a display face disposed within the housing for visually displaying the first pressure of material disposed within the tank and the second pressure of material disposed within the regulated outlet;

a first indicator disposed within the single housing operable for providing a visual indication of the pressure of material disposed within the first pressure source; and

a second indicator disposed within the single housing operable for providing a visual indication of the pressure of material disposed within the second pressure source,

wherein the first and second indicators of the dual gauge assembly provide a simultaneous visual indication of the first pressure of the material disposed within the tank and the second pressure of the material disposed within the regulated outlet.

13. The air compressor of claim 12, wherein the first and second ports are coaxial.

14. The dual gauge assembly of claim 12, further comprising an O-ring configured for pneumatically isolating the first port from the second port.

15. The dual gauge assembly of claim 12, wherein the first port and second port are disposed within a threaded shaft.

16. The dual gauge assembly of claim 12, wherein the first and second indicators rotate in a single direction.

17. A dual gauge assembly, comprising:

a single housing; and

a means for providing visual indication of two different pressure sources within the single housing.

18. The dual gauge assembly of claim 17, wherein means for visual indication includes a first indicator corresponding to a first pressure of material disposed within a first pressure source and a second indicator corresponding to a second pressure of material disposed within a second pressure source.

19. The dual gauge assembly of claim 18, wherein the first pressure source is a tank and the second pressure source is a regulated outlet.

20. The dual gauge assembly of claim 17, wherein the means for providing visual indication of two different pressure sources within the single housing includes a first port and a second port pneumatically coupling the two different pressure sources to the means for providing visual indication.
