Mechanism of stop of end of career ascending for hydraulic elevators, consisting of a cylinder of little height, provided with a slot in which slides an elongated rectangular piece, driven by a spring that tends to push it downwards and by an outgoing ridge of the lower part of the lifting piston pushes it upward, causing the upper part of this sliding part to act as a valve, closing the oil inlet progressively, thus stopping the piston gently at the end of its stroke.
