A thermal by-pass valve for a heat exchange circuit includes a housing forming a chamber and a by-pass valve port. The valve port is located between first and second sections of the chamber. First and second oil ports open into the first section. At least a third port opens into the second section. A thermally sensitive actuator is mounted in the first section and has a body and a piston located at one end. The body is movable in the chamber in response to piston extension. A valve member is mounted on the body and is movable by the piston. A spacer projects from and is connected to the body and forms a passage through which the piston extends. The spacer acts to maintain the adjacent end of the actuator body at least the length of the passage away from the chamber end. |
