This patent describes an altitude compensating fuel mixture controller for a carbureted automotive vehicle engine comprising: (a) a supporting housing; (b) an aneroid bellows connected to the housing; (c) a control valve assembly having a pressure input port connected to a pressure source related to an intake manifold pressure, a vent port connected to atmosphere, a pressure output chamber, and valving structure movable from a predetermined position to alter communication between the output chamber and one of the input and vent ports to change an output pressure in the output chamber, (d) a force transmitting member supported by the body for transmitting force between the aneroid bellows and the valving structure, and; (e) a pressure actuated fuel mixture controlling valve communicating with the output port and supported by the body; (f) the force transmitting member effective to transmit incremental motion of the bellows to the-valving structure in response to sensed atmospheric pressure reduction below a predetermined level; and (g) the output pressure changing to produce a feedback pressure force acting on the differential pressure responsive means to oppose the incremental bellows motion and to return the valving structure to the predetermined position.
