Abstract

A pneumatic control apparatus and method controls gas pressure inside a tire mounted on a wheel which rotates about the centerline of an axle. A bleeder valve is mounted on a body coaxially aligned with the axle centerline and is in fluid connection with a pneumatic fitting on the tire. The bleeder valve allows gas inside the tire to be relieved to the atmosphere when the gas is above a set pressure. The coaxial alignment of the bleeder valve with the axle centerline permits the bleeder valve to relieve gas pressure unaffected by centrifugal forces.

Claims

1. A pneumatic control apparatus for controlling gas pressure inside a tire mounted on a wheel, the wheel being rotatable in operative connection with an axle, wherein the axle is rotatable about an axle centerline, and wherein the wheel is in supporting connection with a pneumatic fitting, wherein the pneumatic fitting is in fluid communication with the inside of the tire, the apparatus comprising:

a body, wherein the body;

has a circumferential groove;

is releasably connectable to the axle by a set screw cooperatively engaging the axle and the groove; and

is coaxially aligned with the axle centerline;

a bleeder valve mounted in supporting connection with the body, wherein the bleeder valve is coaxially aligned with the axle centerline, and wherein the bleeder valve enables gas above a set pressure to pass to atmosphere; and

a tube, wherein the tube fluidly connects the bleeder valve and the pneumatic fitting whereby gas above the set pressure is relieved from the tire.

2. The apparatus of claim 1 wherein the body is cylindrical.

3. A pneumatic control apparatus for controlling gas pressure inside a tire mounted on a wheel, the wheel being rotatable in operative connection with an axle, wherein the axle is rotatable about an axle centerline, and wherein the wheel is in supporting connection with a pneumatic fitting, wherein the pneumatic fitting is in fluid communication with the inside of the tire, the apparatus comprising:

a body wherein the body;

is releasably connectable to the axle; and

has a fluid passage terminating at a first opening on a surface of the body and originating at a second opening on a surface of the body;

a bleeder valve mounted in supporting connection with the body, wherein the bleeder valves;

is coaxially aligned with the axle centerline;

is in fluid connection with the first opening; and

enables gas above a set pressure to pass to atmosphere; and

a tube, wherein the tube is in fluid connection with the second opening and fluidly connects the bleeder valve and the pneumatic fitting, whereby gas above the set pressure is relieved from the tire.

4. The apparatus of claim 3 wherein the first opening is in threaded connection with a coupling, and wherein the bleeder valve is in releasable connection with the coupling.

5. The apparatus of claim 3 wherein the second opening is in threaded connection with a fitting, and wherein the tube is in releasable connection with the fitting.

6. The apparatus of claim 3 wherein the first opening is in threaded connection with a coupling and wherein the second opening is in threaded connection with a fitting, and wherein the bleeder valve is in releasable connection with the coupling and the tube is in releasable connection with the fitting.

7. The apparatus of claim 3 wherein the body has a second passage terminating at a first opening on a surface of the body and originating at a second opening on a surface of the body, and wherein the tube passes through the second passage.

8. The apparatus of claim 7 wherein the first opening of the first passage is in threaded connection with a coupling, and wherein the bleeder valve is in releasable connection with the coupling.

9. The apparatus of claim 7 wherein the second opening of the first passage is in threaded connection with a fitting, and wherein the tube is in releasable connection with the fitting.

10. The apparatus of claim 7 wherein the first opening is in threaded connection with a coupling and wherein the second opening is in threaded connection with a fitting, and wherein the bleeder valve is in releasable connection with the coupling and wherein the tube is in releasable connection with the fitting.

11. A method for controlling gas pressure inside a tire mounted on a wheel, the wheel being rotatable in operative connection with an axle, wherein the axle is rotatable about an axle centerline, and wherein the wheel is in supporting connection with a pneumatic fitting, wherein the pneumatic fitting is in fluid communication with the inside of the tire, the method comprising:

rotating a bleeder valve, wherein in bleeder valve;

is in supported connection with a body, wherein the body;

has circumferential grove and is releasable connectable to the axle by a set screw cooperatively engaging the axle and the grooved; and

is coaxially aligned with the axle centerline;

in coaxially aligned connection with the axle centerline; and

enables gas above a set pressure to pass to atmosphere; and

fluidly connecting the bleeder valve and the pneumatic fitting with a tube, whereby gas above the set pressure is relieved from the tire.

12. A method for controlling gas pressure inside a tire mounted on a wheel, being rotatable in operative connection with an axle, wherein the axle is rotatable about an axle centerline, and wherein the wheel is in supporting connection with a pneumatic fitting, wherein the pneumatic fitting is in fluid communication with the inside of tire, the method comprising:

rotating a bleeder valve, wherein the bleeder valve;

is in supported connection with a body, wherein the body is;

coaxially aligned with the axle centerline;

has a fluid passage terminating at a first opening on a surface of the body and originating at a second opening on a surface of the body, and

is coaxially aligned with the axle centerline; and

enables gas above a set pressure to pass to atmosphere;

fluidly connecting the bleeder valve and the pneumatic fitting with a tube wherein the bleeder valve is in fluid connection with the first opening and the tube is in fluid connection with the second opening;

whereby gas above the set pressure is relieved from the tire.

13. The method of claim 12 wherein the first opening is in threaded connection with a coupling, and wherein the bleeder valve is in releasable connection with the coupling.

14. The method of claim 12 wherein the second opening is in threaded connection with a fitting, and wherein the tube is in releasable connection with the fitting.
