Abstract: ABSTRACT OF THE DISCLOSURE     An hydraulically operated striking apparatus for driving a rock drill comprises a body having an axial, cylindrical, interior space with an inwardly protruding annular member. A cylindrical piston is positioned in the space in sliding contact with the protruding annular member, and the piston has a canal in its outer surface. The body, the annular member and the piston define two annular spaces and an annular distributing valve in caused to slide within one of the spaces under fluid pressure.  The two spaces communicate with each other by means of the piston canal when the piston is in a first slidable position, and the protruding annular member prevents communi-cation between the two spaces when the piston is in a second slidable position. The piston is provided with an axially disposed extension which, in combination with an outlet, serves to permit a third annular axial space to communicate with either an inlet or an outlet at all times.  After the fluid under pressure has moved the distributing valve, it is con-ducted to a rotating hydraulic motor and drives the motor to rotate the apparatus.

Abstract: ABSTRACT           In a telescoping mechanism such as a hydraulic ram, the facing cylindrical surfaces of the telescoping members are formed with grooves in which stop rings are fitted.         According to the invention, the stop rings are separate from bearing elements acting between the telescoping members and have interengaging races inclined to the direction of relative telescopic movement.         This arrangement ensures that, upon an impact between the stop rings, a substantial proportion of the impact is absorbed by expansion of one stop ring and contraction of the other stop ring.
