Abstract

In a setting member for controlling the quantitative flow of a fluid, particularly for the regulating of the idling speed of an internal combustion engine, having an electromagnet and an armature which is movable by the electromagnet in opposition to the force of a spring, a first hollow space to which the fluid can be fed and a second hollow space from which the fluid can be removed are connected to each other by a constriction through which a piston attached to the armature passes upon movement between a position in current-less state and the greatest deflection of the armature. In the case of the failure of the current fed to the electromagnet a medium quantity of flow is established.
