LIQUID PRESSURE STRIKING DEVICE ABSTRACT OF THE DISCLOSURE A liquid pressure striking device defines a double-acting cylinder in a main body thereof having a tool at its lowest portion, and the double-acting cylinder houses therewithin a piston having an upper rod and a lower rod. The lower rod suspends a hammer for striking the tool, and the upper rod is provided on its outer circumference with a change-over valve mechanism which comprises a valve body of special structure for automatically switching the liquid flow under pressure by vertical movement of the piston, and a valve chamber having a plurality of concaves for controlling said valve body. Above the upper part of the valve chamber, there is provided an accumulator serving as a cap or cover of the main body. The main body is formed with an inlet passage of the liquid and an outlet passage, communicating with the accumulator and the valve chamber. Between the inlet and outlet passages, a special return springless actuating valve intervenes which is furnished with a circuit for directing the liquid to the outlet from the inlet without introducing it into the main body of the device, when the main body is not actuated. - 1 -
