摘要： An object of the invention is to provide an improved technique for lessening an impact force caused by rebound of a tool bit after its striking movement in an impact power tool. The representative impact power tool (101) comprises a tool body (103), a hammer actuating member (119,145), a tool holder (137), a driving mechanism (143), a weight (141;141c) placed in contact with the hammer actuating member to move rearward by a reaction force transmitted from the hammer actuating member when the hammer actuating member performs a hammering operation on the workpiece and an elastic element (165) elastically deformed when the weight moves rearward in the tool body to push the elastic element such that the elastic element absorbs the reaction force transmitted to the weight. The weight is defined by the cylinder (141) or a rear cylinder element (141c) of the cylinder.

摘要： It is an object of the invention to provide rational placement and improved vibration reducing performance of a dynamic vibration reducer in a power tool having the dynamic vibration reducer. A hammer drill 101 embodied as a power tool according to this invention has a body 103; a driving motor 111, a motion converting mechanism 113 and a dynamic vibration reducer 151 which are housed within the body 103; and a handgrip 105 designed to be held by a user and connected to the body 103 in a tool rear region rearward of the driving motor 111. The motion converting mechanism 113 is disposed in a tool front region forward of the driving motor 111 in an axial direction of a hammer bit 119 and converts rotation of the driving motor 111 into linear motion and transmits it to the hammer bit 119. The dynamic vibration reducer 151 includes a dynamic vibration reducer body disposed in an intermediate region between the motion converting mechanism 113 and the handgrip 105 and having a housing space, a weight disposed within the housing space of the dynamic vibration reducer body in such a manner as to be linearly movable in the axial direction of the hammer bit 119, and a coil spring that extends between front and rear surfaces of the weight and the dynamic vibration reducer body in the axial direction of the hammer bit 119 and elastically supports the weight in the axial direction of the hammer bit 119. The dynamic vibration reducer reduces vibration of the tool body 103 during operation by linear movement of the weight elastically supported by the coil spring in the axial direction of the hammer bit 119.

摘要： The invention relates to a percussion device having a body (1a) and a percussion piston (2) moving therein, pressure fluid spaces (3, 4) in the rear and front ends of the percussion piston (2) and pressure fluid channels for feeding pressure fluid into the percussion device. The percussion piston (2) and the control valve (5) comprise surfaces, which, when aligned, substantially close the pressure fluid flow from the pressure fluid space (4) locating behind the percussion piston (2) in front of the control valve (5), whereby the produced pressure displaces the control valve (5) to another position.

摘要： An axial bearing includes a first piston and a second piston. Axial contact surfaces between the pistons are arranged in the same pressure space. The same pressure fluid fed to the axial bearing acts on the contact surfaces and on working pressure surfaces of the pistons. A rock drilling machine is also provided with such an axial bearing.

摘要： La foreuse décrite comporte un cadre (6), un dispositif à percussion (1) fixé dans ledit cadre, et une partie de queue (2) située sur le prolongement axial du dispositif de percussion. La cadre (6) comporte un outre un palier axial constitué par une pluralité de pistons (4a, 4b) devant recevoir les forces axiales agissant sur le cadre (6) par l'intermédiaire de la queue (2). La course de certains pistons (4b) vers la partie avant de la foreuse est limitée de sorte que lorsqu'ils se trouvent dans leur position antérieure et que la queue (2) se trouve maintenue par les pistons (4a, 4b), la queue (2) est située sensiblement à son point de percussion optimal.
