Abstract

A tire pressure control system includes a tire mounted on a wheel that is connected to an axle, with pneumatic fittings communicating with an interior of this tire. A digital pressure switch has a pair of pneumatic lines that extend from it. These pneumatic lines connect to the pneumatic fittings so that the digital pressure switch communicates with the tire. An electronic solenoid valve communicates with the digital pressure switch by electrical connection to communicate with the interior of the tire. The electronic solenoid valve operates in a corresponding relationship to the interior of the tire so gas above a set pressure can pass to atmosphere. A battery assembly powers and activates the digital pressure switch, and further powers the electronic solenoid valve through the digital pressure switch. A housing houses the digital pressure switch, the electronic solenoid valve, and the battery assembly.

Claims

1. A tire pressure control system, comprising:

a tire mounted on a wheel, the wheel rotatably connected to an axle;

a pair of pneumatic fittings in fluid communication with an interior of the tire;

a selectively adjustable digital pressure switch;

a pair of pneumatic lines, the pneumatic lines extending from the selectively adjustable digital pressure switch and removably connected to the pneumatic fittings such that the selectively adjustable digital pressure switch communicates with the tire;

an electronic solenoid valve, the electronic solenoid valve in communication with the selectively adjustable digital pressure switch by electrical connection so that the electronic solenoid valve is in communication with the interior of the tire, wherein the electronic solenoid valve is selectively operated by the selectively adjustable digital pressure switch in corresponding relation to the interior of the tire to enable gas above a set pressure to pass to atmosphere;

a battery assembly, the battery in communication with the selectively adjustable digital pressure switch to power the selectively adjustable digital pressure switch and the solenoid valve through the selectively adjustable digital pressure switch, wherein

the battery assembly distributes electrical charges to activate the selectively adjustable digital pressure switch to selectively operate the electronic solenoid valve; and

a housing adapted to be removably secured within the axle, wherein the selectively adjustable digital pressure switch, the electronic solenoid valve, and the battery assembly are housed within the housing.

2. The tire pressure control system according to claim 1, wherein each pneumatic fitting out of the pair of pneumatic fittings is an assembly that includes a male fitting and a female fitting.

3. The tire pressure control system according to claim 1, wherein the electrical connection includes electrical wires.

4. The tire pressure control system according to claim 1, wherein the battery assembly further comprises a battery terminal connector.

5. The tire pressure control system according to claim 1, wherein the battery assembly further comprises an on/off switch for selective operation.

6. The tire pressure control system according to claim 1, wherein the housing is removably secured within the axle by a mounting configured for pinning the housing to the axle.

7. A pressure control device, comprising:

a pair of pneumatic fittings in fluid communication with a fluid;

a selectively adjustable digital pressure switch;

a pair of pneumatic lines, the pneumatic lines extending from the selectively adjustable digital pressure switch and removably connected to the pneumatic fittings such that the selectively adjustable digital pressure switch communicates with the fluid;

an electronic solenoid valve, the electronic solenoid valve in communication with the selectively adjustable digital pressure switch by electrical connection so that the electronic solenoid valve is in communication with the fluid, wherein the electronic solenoid valve is selectively operated by the selectively adjustable digital pressure switch in corresponding relation to the fluid to enable a gas above a set pressure to pass to atmosphere;

a battery assembly, the battery in communication with the selectively adjustable digital pressure switch to power the selectively adjustable digital pressure switch and the solenoid valve through the selectively adjustable digital pressure switch, wherein the battery assembly distributes electrical charges to activate the selectively adjustable digital pressure switch to selectively operate the electronic solenoid valve; and

a housing, the selectively adjustable digital pressure switch, the electronic solenoid valve, and the battery assembly being housed within the housing.
