Abstract

A valve 12 opens to permit idling mixture flow to downstream of the carburettor throttle valve when its actuator diaphragm 37 is subject through an inlet 15 to the suction downstream of the throttle valve which occurs at idling. At lower and higher suctions the valve cones 32, 33 engage the seats 30, 31.The inlet 15 is connected, under the control of a selector valve (20), Fig. 1 (not shown), to the carburettor induction passage by a first passage (16) having inlets (17, 18) both of which are downstream of the throttle valve when closed but one of which becomes upstream when the throttle valve is opened or to a second passage (21) opening to the induction passage inlet or the atmosphere. The selector valve may be operated by an electromagnetic or suction actuator. The valve 12 closes at overrunning and when the ignition is switched off. <IMAGE>
