Abstract

The invention relates to a double- acting hydraulic jack. The jack body (11) contains a cylindrical liner (20) having a cylindrical bore (21) in which a piston (14) is guided. The outer surface of the liner has channels or passages for working fluid. They are in communication with orifices (18) for admitting fluid into the jack body and for returning it therefrom. The invention is particularly applicable to hydraulic jacks for use in vibrating devices in machine tools.
