ABSTRACT:
An improvement is disclosed for a valve arrangement for adjusting the idling speed of an engine of the type having an intake manifold and a throttle valve in the manifold. In this arrangement there is a bypass of the throttle valve, and an electromechanical setting element and a solenoid connected to a closure member for the bypass via a setting member. A return spring biases the setting member in a closing direction and the solenoid can urge the setting member in an opening direction against the force of the return spring. The closure member is urged in the opening direction by pressure on the admission side of the manifold. This admission side is connected to a chamber having a moveable wall connected to the closure member. In accordance with the improvement the chamber is connected to the intake side of the manifold by a connection which includes a valve which is adapted to close the connection during a control process.
