Definitions
- actuators for controlling internal combustion engines used a control between a minimum and a maximum position hold.
- a typical implementation is with two spring elements, one of which in Opening direction and one acts in the closing direction and of which in each case a spring element does not work in a subarea.
- the spring acting in the closing direction typically becomes designed as a helical or spiral spring, while in the opening direction acting spring as a screw and a leaf spring is executable.
- Actuators for the control of internal combustion engines with a de-energized position between a minimum and maximum position for example, from DE 36 31 283 and DE 39 08 596 known.
- the known from these solutions actuators include two spring elements, one of which in the opening direction and one in the closing direction acts.
- a device with a servomotor for engagement in a transmission device known.

- the control is with a rotary link and the Control member connected to a second rotary link.
- a tension spring provided on the one hand on the first rotary member and on the other hand on the second Rotary member acts in the sense that the rotary members are anxious, a rotational movement relative to each other to perform a stop of a rotary member to a stop the other rotary member comes to rest. It is disclosed a third rotary member, with Plant comes.
- a third rotary member with which the servomotor in operative connection stands and by that the second rotary member is rotatable. Between the second and the third rotary member is a coupling which in certain positions of this Rotary links to each other is not effective.
- the third rotary member is at least one indirectly or directly acting on the third rotary member remindfitung in a Rest position retractable.
- the reverse torsional suspension can either only in one direction be effective or depending on the position of the third rotary member either in one or be effective in the other direction of rotation.
