An improved film type air temperature control valve for an automotive HVAC assembly has a flexible, apertured belt that wraps closely around both faces of a heater core case internal to the HVAC housing. Winding and unwinding of the belt around the heater core case, and across a heater core bypass passage, simultaneously opens up more of the bypass passage as it closes off more of the heater core faces, and vice versa. Because of the close conformance of the belt to and across the heater core faces, both faces of the always hot heater core can be complet...
[ We claim:] [1.] An automotive heating and air conditioning assembly with improved temperature control, comprising:a hollow housing through which forced air flows;at least one forced air outlet;an evaporator core inside of said housing, upstream of said air outlet through which substantially all forced air flows;a heater core located in said housing between said evaporator core and said housing air outlet, said heater core sized so as to fill less than the entire internal area of said housing, thereby leaving a bypass opening passage around said heater ...
