Device for controlling at least one throttle cross-section at least one

Device for controlling at least one throttle cross-section at a control

An apparatus for assisting in governing the idling rpm of an internal engine including a bypass line that bypasses a throttle valve in an air intake tube. A rotary slide valve secured to one end of a shaft which is controlled by a motor is rotatable in the bypass line to adjust air flow through the bypass line. The bypass line is integral with a lid-shaped housing part in which roller bearings juxtaposed the rotary slide valve is secured. The upper end of the shaft is rotatable in bearings carried by an upper housing part. The housing parts are secured together in axial alignment with each other.

Governing apparatus for the idling rpm of an internal combustion engine

In control motors having an armature rotatable counter to a spiral spring, a problem arises that the set force of the spiral spring can be changed by the process of installation. The disclosed control motor is intended to enable setting of the force of the spiral spring after installation. To enable setting of the force of the spiral spring after installation, relative to which an armature of a control motor is rotatable, a shaft on which the armature is supported is screwed with a screw end into a threaded bore of a housing bottom end. Connected to the shaft is an adjusting element, which with a driver arm engages an end portion provided on the outer end of the spiral spring. By rotating the ends of the shaft, which are accessible from outside, the force of the spiral spring can be changed. The invention is preferably applicable to idling adjusters, but it is not limited to this field of application.
