Abstract
Selflocking lock cylinder 1 enclosed in a linear motor, and of the type, which incorporates a piston 14, which is movable in the longitudinal direction of the cylinder, and which is movable together with a piston rod 13, and where in the cylinder is provided at least one locking mechanism situated adjacent anyone of the external positions for the piston rod 13, which locking mechanism has a radially movable first locking member in the form of balls 18 inserted in a retainer 17, and which balls by means of an operating mechanism which is movable to a limited degree with the piston rod, are arranged to be guided to locking engagement in cooperation with a second locking member, and to retain the first locking member in locking position in the second locking member, and where the locking effect can be abrogated first after supply of pressure fluid, whereby the second locking member is a locking groove 12, which is separated from the piston rod 13 and situated at a radial distance from this.
