ABSTRACT OF THE DISCLOSURE An idle control valve (10) for adjusting the idle position of a vehicle throttle lever includes a housing (12) having a pair of diaphragm assemblies (18, 20) which divide the housing into three chambers (22, 24, 26). The chamber (26) defined between the diaphragm assemblies is communicated with atmospheric pressure, and the other chambers (22, 24) are communicated with engine manifold vacuum. A valve member (38) controls communication through a vent (74) in the diaphragm assembly (20) to position the latter as a function of the variations in engine manifold vacuum to thereby control the position of the plunger (62) which is attached to the diaphragm assembly (20). The diaphragm assemblies (18, 20) include projecting portions (36, 52) which telescope within one another when the vehicle engine is turned off and atmospheric pressure is communicated to all three chambers to permit the plunger to be withdrawn into the housing.
