A separate throttle within each of a pair of air inlet passages for an automobile internal combustion engine comprises a variable restriction diffuser designed for sonic velocity gas flow through its region of maximum restriction throughout substantially the entire operating range of the engine. The diffuser in one of the pair of passages comprises a movable orifice member and a fixed closure member. The diffuser in the other of said passages comprises a fixed orifice member and a movable closure member. The movable members in the two passages are movable in axially opposite direction with respect to the inlet air flow to vary the aforesaid maximum restriction for their respective passages and are operatively coupled with the throttle control linkage to effect such movement simultaneously, whereby the force required to move either movable diffuser member against the force of the flow of inlet fuel and air within its passage is counterbalanced by an oppositely directed force exerted by said flow on the other movable diffuser member.
In a fuel supply means for an automobile engine, inlet induction passage means, fuel supply means for supplying fuel to said passage means, said passage means having upstream inlet means for receiving air and having two downstream outlet conduits for discharging a fuel-air mixture, means defining a part of each outlet conduit downstream of said fuel supply means comprising an orifice member and an associated closure member arranged for relative movement with respect to each other axially of their associated conduit, each orifice member having an orifice for conducting the flow of said mixture therethrough, each closure member being cooperable with its associated orifice member to effect a variable restriction for the associated orifice in accordance with the relative axial positions of said members, and means for effecting said relative movement to decrease or increase the restrictions of the two orifices in unison comprising means for connecting the orifice member in one outlet conduit with the closure member in the other outlet conduit for moving one of the last named two members in the direction of the mixture flow in the associated outlet conduit and for simultaneously moving the other of the last named two members oppositely to the direction of the mixture flow in the associated outlet conduit.
