Throttle valve adjuster

Abstract

Abstract A throttle valve adjuster with which a quantity of air supplied to an internal combustion engine during idling, for instance, can be adjusted. The adjuster comprises a stator which is supported within a throttle valve pipe and which is rotated by actuation of a driving pedal. Supported inside the stator is an armature, which is firmly connected to the throttle valve. Located on the stator is a coil winding, which initiates a magnetic flux that acts upon the armature via two oppositely disposed guide shoulders which forms between the armature air gaps and the guide shoulders. The armature rotates relative to the stator counter to the force of a spring. The entire rotational movement of the throttle valve is thus a combination of the relative movement between the stator and the throttle valve pipe and the relative movement between the armature and the stator. If the driving pedal is not actuated, for instance as in engine idling, then the flow cross section uncovered in the throttle valve pipe by the throttle valve is a function of the rotational angle between the armature and stator and hence of the intensity of the current flowing through the coil winding.
