Abstract
A device is proposed for controlling a flowthrough cross section in a controlled line, in particular in a line carrying operating medium in internal combustion engines, in order to exert influence on the idling rpm of the engine. The device includes an actuation member comprising an immersion-coil magnet system which engages an actuation shaft with which a first valve member and a second valve member are connected. The coaxial guidance of the actuation shaft in the valve housing is effected by means of two guide diaphragms held in place relative to one another by attachment to the housing on their circumference. The valve members are identical in shape and each cooperates with a valve seat provided in a valve plate in the identical direction. The air flow may be effected via inlet apertures provided in the tubular section of the valve housing exhausting via the opened valve seats to outlet apertures in the cap.
