ABSTRACT:
A thermostatic valve for intake air temperature compensation for an internal combustion engine includes a housing formed with first, second, and third openings leading, respectively, to the atmosphere, a negative pressure motor, and the intake manifold of the engine. To this housing is secured a temperature sensor including a piston rod to be actuated by a thermally expandable element whose volume increases or decreases with a change in temperature. A valve element to be moved into and out of contact with a valve seat by the piston rod of the temperature sensor is accommodated in a casing. Inside the casing a holed partition member is disposed between the first and third openings and between the second and third openings, and a check valve designed to open in one direction only is located between the partition member and the third opening.
