    • A pneumatic impact mechanism for driving rod-like members having a hollow cylindrical casing with a tail portion and a front end portion. The casing accommodates a reciprocating stepped hammer piston defining in the casing, on the tail portion side, a variable volume rear end work chamber in permanent communication with a source of compressed air. The stepped hammer piston defines, on the side of the front end portion, a variable volume front end work chamber.The stepped hammer piston has a through-passing axial bore, and its small-diameter portion cooperates with the tail portion of the casing and has radial passages. There is provided a tubular guide member or element for receiving the rod-like member arranged coaxially with the stepped hammer piston and casing and secured to the tail portion and to the front end portion of the casing in such a manner as to cooperate with the stepped hammer piston and define therewith, with the outer periphery thereof an axial passage. A clamp for engaging the individual rod-like members is rigidly removably secured to the front end portion of the casing. The front end-work chamber communicates, at regular intervals, with atmosphere through the axial passage and radial bores when the stepped hammer piston is in its rear end position and with the rear end work chamber when the stepped hammer piston is in the front end position to deliver blows to the casing under the action of compressed air fed to the work chambers.

    • A reversible percussion device, having a casing 1 in which is installed a movable striker and a system for distributing fluid under pressure for causing the striker 4 to move for both forward and rearward movement functions of the device. The system comprises a control member 9 for controlling the distribution of fluid under pressure for both functions, which is movably coupled to the striker 4 and has a mechanism for locking it with respect to the casing 1 in two control positions, corresponding to the two functions of the device. According to the invention, the mechanism for locking the control member 9 in the position enabling the forward movement functions of the device comprises a body 11 movable relative to the control member 9. The body 11 is installed in such a manner as to have a portion adapted to be acted upon by fluid under pressure so as to engage the casing 1 in one position to axially lock the control member 9 with respect to the casing 1 and in the other position to enable the mobility of the control member 9 relative to the casing 1 when the device is switched over for the rearward movement function.
