摘要： 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.

摘要： The device comprises a hollow cylindrical body, pointed front at its end which device accommodates a striker forming the front working chamber in said body, and has a cylindrical space at its rear end. Said space receives an air-distributing and reversing mechanism, thus forming the rear working chamber. The air-distributing and reversing mechanism has a bushing which is fixed relative to the body, and an axially movable bushing, both bushings being arranged coaxially, spring-loaded in the axial direction relative to each other, and forming a chamber located in the front part of said mechanism, with the chamber communicating with a source of compressed air and intended to move the movable bushing during reversal of the device. The side wall of the movable bushing has a through hole and a longitudinal external recess, both made in such a manner that during the forward travel of the device the through hole places the chamber formed by the bushings in communication with the source of compressed air while during the backward travel the through hole is covered by the fixed bushing and the chamber formed by the bushings communicates with the atmosphere through the external longitudinal recess.
