ABSTRACT:
A Cylinder for pressurized fluids, such as oil, air or the like, including of a cylindrical nozzle and a pair of heads designed to be attached to the ends of the nozzle, characterized in that two annular grooves are made partly in the cylinder liner and partly in each of the two heads for the purpose of locking the heads, and that elements designed to be inserted into the grooves to lock the heads into position are filled. In particular the locking elements are constituted by roller bearings the axis of which is parallel to the axis of the nozzle and which engage with the walls of the grooves, preventing axial movements of the heads in relation to the nozzle. Preferably the grooves are made partly on the inner surface of nozzle and partly on the outer surface of a head element which is inserted into the nozzle.
