Device for governing the idling rpm of an integral combustion engine

A device for governing the idling rpm of an internal combustion engine by controlling a quantity of operating fluid that flows in a flow line to the engine, having an electromagnetic regulating drive (22) disposed in a drive housing (15) that is activated by a speed-dependent control signal, a regulator housing (13) and an adjusting element (21) coupled to the regulating drive, said adjusting element is engaged by a first spring (36) and at whose end remote from the regulating drive, a valve element (29) is disposed, by means of which a closing element (30) engaged by a second spring (28) is displaceable from a closing position into an opening position when the regulating drive is activated, and the valve element assumes an open position when the regulating drive is not activated and a closed position during increasing activation, the closing element (30) has a first frustoconical surface (37) that rests against a first corresponding surface (44) embodied on the regulator housing (13) in the closed position of the closing element (30) and, with this surface, forms a first conical seat (38), and has a second frustoconical surface (39) that rests against a second corresponding surface (45) embodied on the valve element (29) in the open position of the closing element (30) and, with this surface, forms a second conical seat (40), and that the first and second springs (28, 36) are disposed parallel to each other such that when the valve element (29) is adjusted into the open position or the closed position, only the force of the first spring (28) is effective.
