Abstract
A valve for a control system of a vehicle includes a plunger slidably supported in a valve housing. Within the housing is a valve seat member that defines a valve seat configured for engaging the plunger in a closed configuration. The edges of the valve seat member are slightly spaced from the housing, and a resilient support element such as an o-ring is disposed between the valve seat member and the housing to permit lateral motion of the valve seat member relative to a long axis of the plunger as the plunger moves to the closed configuration.
