Abstract
A temperature responsive valve particularly adapted for use in a manual valve of a vehicular automatic transmission control is shown in which the temperature responsive valve has a generally cylindrical housing with a reduced diameter section and a cylindrical valve element rotatably received in the reduced diameter section. A thermostatic coil is coupled to the valve element to control the angular position of the valve element. Apertures are provided in both the housing and the valve element forming a variable orifice for pneumatic fluid which flows into an open end of the housing and out of a minimum fixed orifice in the reduced diameter section and, depending on the temperature, may also flow through the variable orifice.
