TIRE INFLATION SYSTEM AND METHOD

摘要

A tire inflation system includes an air supply source in selective fluid communication with a tire via a pneumatic conduit. A first valve is in fluid communication with the pneumatic conduit in between a first portion and a second portion of the conduit. A second valve that includes a vent channel is in fluid communication with the pneumatic conduit between the second portion and a third portion of the conduit. A rotary union is in fluid communication with the third portion of the conduit adjacent the tire. A first pressure indicator is in fluid communication with the first portion of the pneumatic conduit and a second pressure indicator is in fluid communication with the third portion of the pneumatic conduit. An inflation pressure of the tire is measured with a step-up procedure and the tire is inflated with an extended-pulse procedure.
