Abstract: A wheel valve assembly having a body portion coupled with a cover portion. A diaphragm disposed between the body portion and the cover portion. A first biasing member disposed between the cover portion and the diaphragm in a cover cavity defined thereby. A control cavity defined by the body portion and the diaphragm, and at least one control port defined by the body portion and in fluid communication with the control cavity. A tire port defined by the body portion and in selective fluid communication with the control cavity. A first and second conduit disposed in the body portion in fluid communication with a third and fourth conduit disposed in the cover portion. An equalization valve assembly disposed in one of the conduits to control fluid communication between the cover cavity and the control cavity.

Abstract: A valve assembly for a central tire inflation system is provided. The valve assembly includes a first housing having a first port connected to a second port via a cavity. The second port is in fluid communication with a wheel assembly. A biasing member is disposed in the cavity adjacent a first perforation formed in the first housing. A valve member is contacted by the biasing member. The valve member includes a first portion having an outer surface which is unbroken adjacent an end to allow a pressurized fluid to flow around it. The first portion reduces in diameter toward the end.
