Abstract
A vehicle tire inflation system includes an air supply that is connected to a vehicle tire by a pneumatic conduit. A pump that is independent of and pneumatically parallel to the vehicle air supply includes an inlet and an outlet. The pump inlet receives air from atmosphere, the pump compresses the air, and the pump outlet is fluidly connected to the pneumatic conduit. When the air pressure in the pneumatic conduit drops below a predetermined level, compressed air from the pump is introduced into the pneumatic conduit, thus increasing the air pressure in the conduit to increase the air pressure that is available to the tire. A reservoir tank, which is also independent of the vehicle air supply, may be in fluid communication with the pump outlet and the pneumatic conduit.
