ABSTRACT:
A linear drive is disclosed comprising a single-acting pneumatic piston cylinder unit, at least one spring which acts against the pneumatic force and loads the piston rod in the direction of one end position, and one form-locking pneumatic locking mechanism respectively for each of the two end positions of the piston rod. The locking mechanism comprises a locking link which can be locked from diametrical sides into one recess of the piston rod respectively; a first control piston which is rigidly connected with the locking link, a second larger control piston which is disposed in a longitudinally movable manner on a supporting tube rigidly connected with the locking link; a spring which presses the second control piston in the direction of its extreme end position; a stop for the second control piston which is fixed to the housing; a valve piston which is coupled in a springy and sealing manner with the second control piston and has a closable throttle duct and an open flow connection from the interior of the second control piston and of the valve piston to the pressure space of the piston cylinder unit.
