ABSTRACT:
A displacement device for a throttle valve of an internal combustion engine in idling condition, has a housing, a diaphragm which is arranged in a chamber in the housing and is operatively connected to the throttle valve, a spring in the chamber, which spring acts with one end against the diaphragm, a vacuum connection to the one chamber, a connection for atmospheric pressure, a coil, and an armature which is axially displaceable in the coil, a valve body being firmly connected to the armature and keeping a connection for atmospheric pressure open or closed corresponding to its instantaneous position. A single connection for atmospheric pressure leads to the chamber and is kept open or closed by the valve body. The connection for vacuum is also kept open or closed by the valve body, the two connections being opened alternately. The valve body is acted on by the spring. The coil current is provided as control variable for the position of the throttle valve.
