Abstract
A vehicle solenoid valve includes an inlet port circumscribed by a rounded cup-shaped valve seat and an outlet port. A two-piece poppet is installed within the valve and includes a non-magnetic poppet shaft connected to a frustum-shaped poppet head. The poppet head includes an integrally formed, rounded nose that is sized and shaped to engage the rounded cup-shaped valve seat. The poppet is movable between an open configuration, wherein the rounded nose is distanced from the valve seat, and a closed configuration, wherein the rounded nose engages the valve seat to block fluid communication through the valve.
