ABSTRACT:
The throttle for the air inlet passage of an automobile internal combustion engine comprises a variable restriction diffuser within the passage and designed for sonic velocity gas flow through its region of maximum restriction throughout substantially the entire operating range of the engine. The diffuser comprises an orifice member and a closure member movable axially in opposite direction within the passage to vary the aforesaid maximum restriction and operatively coupled with the throttle control linkage for such movement, whereby the force required to move either diffuser member against the force of the fuel and air inlet flow within the passage is counterbalanced by an oppositely directed force exerted by said flow on the other diffuser member.
