Device for regulating the idling speed of internal combustion engines

In a device for regulating the idling speed of an internal combustion engine (12) by controlling the quantity of fuel which can be supplied from a fuel tank (10) to the engine via at least two supply lines, the cross-section of a first valve aperture (34) is controlled by a first valve closing member (38a) and that of a second valve aperture (36) is controlled by a second valve closing member (38b). The first and second valve closing members (38a, 38b) can be moved by a servo-drive in such a way that the first and second valve apertures are arranged mutually parallel between the fuel tank and the engine's intake passage. The valve closing members (38a, 38b) are coupled in such a way that, when they are actuated, the first valve closing member (38a) always opens a flow cross-section to the first valve aperture (34) and only then does the second valve closing member (38b) open a flow cross-section to the second valve aperture (36).
