ABSTRACT:
The piston comprises two annular members which are mounted without clearance on a tubular rod. The main annular member receives in a counter bore the other annular member without clearance. The assembly is achieved by means of a mutual forming over of the two annular members which pre-stresses a rigid ring in a groove in the rod, this ring being interposed between the two annular members. The main annular member has a second formed over portion which is engaged in a groove in the rod and is capable of performing the function of the first mentioned forming over in the event of failure of the latter.
Application in control cylinder devices of helicopters.
