ABSTRACT:
Single-acting cylinder-piston unit of plunger type, having a cylinder (1) closed at one end and containing a slidable cylindrical rod (5), the inner end of which presents two adjacent circumferential grooves (18, 28), the first (18) of which acts as a final seat for a split ring (8) defining the limit of the outward stroke of the rod and the second (28) of which acts as a temporary seat for the split ring, enabling the rod with the split ring mounted thereon to be inserted into the cylinder, the second groove (28) being at the inner end of the rod and the first groove (18) being more towards the opposite end of the rod, in proximity to the base, a counteracting member being arranged to interfere with the split ring to cause it to transfer from the second groove to the first groove during the final stage of insertion.
