BI-DIRECTIONAL FLOW THERMOSTAT

摘要

In preferred form a thermostat valve assembly having a sleeve valve member moved by a thermo-sensitive motor from a closed position in which annular valve portions on both ends of the sleeve member are seated against ends of a cup-shaped frame member into an open position in which dual coolant flow paths are provided between the frame member and the outer surface of the sleeve member and through the interior of the sleeve member. The construction of the thermostat lends itself to an in-line assembly method since all parts are installed through the top of the frame member and are concentric with respect to the frame member.
