ARRANGEMENT FOR SAFEGUARDING AGAINST DIRT IN A WORKING CYLINDER

摘要

Device for securing for transport an actuating linkage of an actuating pedal in a motor vehicle, comprising a master cylinder at one end of which there is arranged a stop ring for a piston which is under the pressure of a spring in the cylinder housing. A substantially axially actuated piston rod is provided of which the foot engages through the central bore of the stop ring and acts on the piston. A rotation-securing means for common radial rotation is arranged between the foot of the piston rod and the piston. Furthermore, a blocking mechanism which limits the radial rotation of the piston is arranged between the piston and the stop ring.
