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. 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.

2. The air compressor of claim 1, wherein the first and second ports are coaxial.

3. The dual gauge assembly of claim 1, further comprising an O-ring configured for pneumatically isolating the first port from the second port.

4. The dual gauge assembly of claim 1, wherein the first port and second port are disposed within a threaded shaft.

5. The dual gauge assembly of claim 1, wherein the first and second indicators rotate in a single direction.

6. An air compressor assembly operable for providing pressurized air to a tool, the air compressor assembly comprising:

a pump for producing pressurized air at a first pressure;

an air tank fluidly connected to the pump for storing the pressurized air at the first pressure;

a high pressure pipe fluidly connected to one of the pump and the air tank;

a pressure regulating valve including an inlet, fluidly connected to the high pressure pipe, and an outlet, the pressure regulating valve reducing the pressurized air from the first pressure at the inlet to a lower second pressure at the outlet;

a low pressure pipe fluidly connected to the outlet of the pressure regulating valve;

a dual gage assembly including a single gage face, a first a pressure indicator and a second pressure indicator, the first pressure indicator fluidly connected to the high pressure pipe for displaying the first pressure and the second pressure indicator fluidly connected to the low pressure pipe for displaying the second pressure.

7. An air compressor assembly according to claim 6, wherein the first pressure indicator and the second pressure indicator provide a simultaneous visual indication of the first pressure and the second pressure.

8. An air compressor assembly according to claim 6 and further including a housing encompassing the dual gauge assembly.

9. An air compressor assembly according to claim 6 wherein the first pressure indicator includes a first air port, and the second pressure indicator includes a second air port.

10. An air compressor assembly according to claim 9, wherein the first and second ports are coaxial.

11. An air compressor assembly according to claim 10, further comprising an O-ring configured for pneumatically isolating the first port from the second port.

12. An air compressor assembly according to claim 9, wherein the first port and second port are coaxially disposed within a threaded shaft.

13. An air compressor assembly according to claim 6, wherein the first pressure indicator and the second pressure indicator rotate in the same direction.
