ABSTRACT:
A device for governing the idling rpm of an internal combustion engine which has a counterbalanced distribution which prevents vibration of a control. In addition, measures are taken by which a pressure of the operating fluid acting on the device can be equalized. An induction core is fixedly attach to a regulator housing to form an axle journal on the induction core. An annular armature is connected to the regulating element, which is seated on the axle journal to be axially displaceable. An elastic diaphragm defined an equalization chamber, which communicates with a connecting line via a line connection. The device is suited in particular for governing the idling rpm of a mixture-compressing internal combustion engine by means of controlling the quantity of intake air flowing in a flow line to the engine.
