ABSTRACT:
A linear three-port actuation valve for a vehicle has a valve seat member that is engaged with a valve body to a location that establishes a desired poppet stroke. The valve body defines a lower seat and the valve seat member defines an upper seat, and a poppet slides within the member to selectively block the lower seat. When the lower seat is not blocked the upper seat is blocked by a ball positioned against the poppet, and vice-versa. Accordingly, the valve seat member aligns the poppet with the lower seat, it aligns the ball with the upper seat, it directs fluid through the upper seat to a control port, and it establishes the desired stroke of the poppet, reducing the number of components and simplifying assembly.
