  • Patent number: 8661886
    Abstract: The disclosed embodiments include a valve stem assembly for a tire pressure monitoring system sensor. The assembly can comprise a valve stem body, and a grommet for purposes of engaging a vehicle wheel. The valve stem body can comprise an attachment end to be attached to a pressure sensor to determine tire air pressure, and an air transfer end to receive a gas to fill the tire. The grommet can further comprise flanges with dimensions such that the grommet can limit movement of the valve stem assembly relative to the vehicle wheel. Methods for installing the valve stem assembly are also disclosed.
    Type: Grant

  • Patent number: 8650945
    Abstract: A valve stem connectible to a tire pressure sensor includes a valve stem body and a grommet attached to the valve stem body. The grommet includes a first flange and a second flange extending radially outward from the valve stem body. A retention member attached to the valve stem body includes a base member and a standoff extending from the base member. The standoff is selectively moveable between a first position in which a distal end of the standoff is disposed at a first radial distance from a longitudinal axis of the valve stem body, and a second position in which the standoff is disposed at a second radial distance from the longitudinal axis, the first radial distance being greater than the second radial distance. An outer peripheral edge of the second flange is disposed at a third radial distance that is less than the first radial distance.

  • Patent number: 8631695
    Abstract: The disclosed embodiments include a valve stem assembly for a tire pressure monitoring system sensor. The assembly can comprise a valve stem body, and a grommet for purposes of engaging a vehicle wheel. The valve stem body can comprise an attachment end to be attached to a pressure sensor to determine tire air pressure. The valve stem assembly can further comprise a cap that is releasably engaged to the valve stem body which can limit movement of the valve stem assembly relative to the vehicle wheel, the cap having a closed end to cover an air transfer end of the valve stem, and a second open end to overlay the valve stem body and grommet.
