ABSTRACT:
The invention relates to an adjustment device (1) for an internal combustion engine, particularly for adjustment of shafts with adjusting members. Heretofore known open/close switches are relatively large and cost-intensive in their production. For this reason, an adjustment device (1) is proposed, in which a set of gears (5) simply comprising a worm (7) and a partial ring worm gear (8) wherein pin magnets are disposed on the partial ring worm gear. The pin magnets (11) work functionally together with a non-moving switch (16) disposed in a housing (2,3) when a signal is produced by means of the magnetic field of the magnets (11) passing by the switch (16), which stops motor (4) and, as the case may be, predetermines a direction change. Thus, a right/left movement of the motor (4), along with a timely turning off of the motor can be achieved with only one external control signal.
