Abstract
An altitude compensation unit for governing the combustion mixture in an automotive vehicle engine carburetor in response to changes in altitude above a predetermined altitude comprising a housing, an aneroid bellows anchored to the housing, and a force balancing pressure transducer valve fixed with respect to the housing. The transducer valve procides an output fluid pressure which varies in relation to the value of a force applied to the valve, with the output pressure force and the input force acting in opposition to each other on a valve transducer element. The transducer element is disposed in a predetermined position when the forces are balanced. A force transmission member supported by the housing transmits force between the capsule and the transducer element. A transducer output pressure responsive actuator alters the combustion mixture in response to output pressure from the transducer.
