ABSTRACT:
A pneumatic adjusting mechanism, especially for application in motor vehicles, which consists of a suction-air servo-motor that includes a working cylinder with a diaphragm piston whose piston rod is stressed by a spring against the action of the suction-air; to provide an adjustment to different adjusting path steps, individual control lines are connected to the working cylinder in places which correspond to the adjusting path steps; all control lines lead to a control switch connected with a suction-air reservoir line while each individual control line is adapted to be selectively connected with this suction-air reservoir line, after previous venting of all control lines, by means of the control switch.
