Abstract
A control installation for the idling rotational speed of internal combustion engines, in which a by-pass control valve is provided that is controlled by an actuating device dependent on the suction pipe pressure and is located in parallel to a throttle valve which can be selectively actuated; the opening cross section of the by-pass valve which increases with increasing suction pipe pressure, thereby increases progressively.
