ABSTRACT OF THE DISCLOSURE A machine having a housing wherein are arranged a step- ped hammer piston adjoining the rear portion of said ma- and a stepped plunger adjoining the rear portion of said ma- chine, said hammer piston and plunger being adapted for an axial movement in said housing. The hammer piston and the plun- ger are parted by a resilient member. The pressure fluid fed into the housing provides for reciprocation of the hammer pis- ton and the plunger. The hammer piston reciprocations consist of forward and return strokes. During the forward stroke the hammer piston transmits impacts tot he tool, The presence of the hammer piston and the plunger with the resilient member in between, increases the power of the hammer piston impacts transmitted to the tool, hence the machine efficiency. The claimed machine may be advantageously used as a hydraulic hammer (quartering hammer) and a hydraulic percussive device for making holes and deep wells in soil.
