ABSTRACT:
The invention relates to hydraulic jack operating systems. The end-of-stroke damping of the jack is produced by an element of the shape of a truncated cone, integral with the stem of the jack, which penetrates into a floating ring and which defines, in this ring, a damping chamber isolated from the remainder of the capacity of the jack. When the stem of the jack makes its return movement, the chamber is re-supplied with oil through passages which were previously obturated by the displacement of the ring at the instant of the damping. The invention is applicable to high speed hydraulic controls for circuit breakers with ultra-rapid operation.
