An assembly for a tire inflation system includes a valve assembly. The valve assembly includes a housing. The housing includes a base portion () and a cap portion (). The base portion has a base perforation (). The base perforation () is in fluid communication with a base cavity. The cap portion () is attached to the base portion (). The cap portion () has a cap perforation () formed therein. The cap perforation () is in selective fluid communication with the base cavity. A piston () is disposed in the base cavity. A first area (A) is defined by the base perforation (), a second area (A) is defined by the lateral area of a cylindrical space between the piston () and the cap portion (), and a third area (A) is defined by the cap perforation (). The second area (A) is greater than the first area (A) and the third area (A).

Valve assembly for a tire inflation system

A tire inflation system wheel valve assembly is provided. The wheel valve assembly may include a body portion coupled with a cover portion. A diaphragm may be disposed between the body portion and the cover portion. The diaphragm and the body portion define a control cavity; and the diaphragm and the cover portion define a cover cavity. At least one control port is in fluid communication with the control cavity. In addition, a tire port is in selective fluid communication with the control cavity. Further, the cover portion defines an aperture in fluid communication with the atmosphere and the cover cavity.

Wheel valve assembly with vent to atmosphere and the tire inflation system made therewith

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.
