Abstract

A tire sealant delivery system comprising a container, a moveable piston disposed within the container, the moveable piston cooperatively engage able with the container such that the piston does not rotate during operation, a threaded shaft cooperatively engaged with the piston and the container, a tube for connecting the container to a receiver, a dispenser comprising, an electric actuator, the electric actuator connectable to the container for rotating the threaded shaft, an air compressor, and a valve connectable to the container and connected to the air compressor, the valve operable to selectively allow dispensing of a tire sealant from the container to a receiving tire, or dispensing of compressed air from the air compressor to a receiving tire.

Claims

1. A tire sealant delivery system comprising:

a container;

a moveable piston disposed within the container, the movable piston cooperatively engageable with the container such that the piston does not rotate during operation;

a threaded shaft cooperatively engaged with the piston and the container;

a tube for connecting the container to a receiver;

a dispenser comprising;

an electric actuator, the electric actuator connectable to the container for rotating the threaded shaft;

an air compressor; and

a valve connectable to the container and connected to the air compressor, the valve operable to selectively allow dispensing of a tire sealant from the container to a receiving tire, or dispensing of compressed air from the air compressor to a receiving tire.

2. The tire sealant delivery system as in claim 1, wherein the container comprises a valve core tool.

3. The tire sealant delivery system as in claim 1, wherein the dispenser comprises a pressure gage.

4. The tire sealant delivery system as in claim 1, wherein the electric actuator is connectable to a vehicle electrical system.

5. The tire sealant delivery system as in claim 1, wherein the piston comprises a hexagonal planiform.

6. A pressurized gas inflation and tire sealant dispensing device comprising:

a mounting assembly;

a gas compressor supported on the mounting assembly for providing pressurized gas;

a valve assembly supported on the mounting assembly, said valve assembly including a pressurized gas inlet, a sealant inlet, an outlet connectable to each inlet for discharge of sealant or pressurized gas, and a valve member for at least partially closing a flow of pressurized gas and a flow of sealant between the respective pressurized gas inlet or sealant inlet and the outlet;

a pressurized gas conduit from the gas compressor to the pressurized gas inlet valve assembly;

a conduit from the valve outlet;

a sealant container for sealant, said container including a sealing outlet, a sealant conduit from the outlet, the sealant outlet connected to the valve assembly sealant inlet, an internal mechanically actuable piston in the container moveable between a sealant filled position and a sealant discharging position in response to mechanical actuation of the piston; and

a mechanical drive assembly on the mounting assembly for mechanically driving the piston in the container intermediate the filled and discharged positions, said drive assembly including a drive rod mechanically engaging said piston.

7. The pressurized gas inflation and tire sealant dispensing device of claim 6 wherein said piston is actuable within said container between said sealant fill position and sealant discharging position independent of said gas compressor supported on said mounting assembly for providing pressurized gas.
