ABSTRACT:
Cushioning apparatus for cushioning a hydraulic jack is disclosed which includes a plunger reciprocably mounted within a blind bore. The plunger sequentially closes off a plurality of axially spaced orifices provided through the wall of the bore as the plunger moves from a first position adjacent the open end of the bore to a second position adjacent its closed end, thereby progressively restricting the escape of fluid from the bore so as to slow the movement of one of the telescopic members of the jack toward another.
