    Abstract: It is an object of the invention to provide an improved technique for lessening an impact force caused by rebound of a tool bit after the striking movement of the tool bit. Representative impact power tool (101) includes a tool body (103), a hammer actuating member (119, 145), a driving mechanism (113, 115), a weight (163) and an elastic element (165). A reaction force that the hammer actuating member receives from the workpiece when performing a hammering operation is transmitted from the hammer actuating member to the weight (163) and then, the weight (163) is caused to move rearward to push the elastic element (165). As a result, the reaction force can be absorbed by the elastic element (165). The elastic force of the elastic element (165) is prevented from acting upon the weight (163) forward beyond the reaction force transmitting position.

    Abstract: The invention relates to a striking hand-held machine tool having a tool holder for holding a striking tool on a working shaft, an electric motor, and a striking mechanism. In the striking direction, the striking mechanism has an exciter piston, a pneumatic chamber, a striker, an intermediate chamber and a rivet snap following one another. A closed channel connects a first channel opening in the pneumatic chamber and a second channel opening in the intermediate chamber. A non-return valve, which shuts off during an air flow from the first channel opening to the second channel opening and opens during an air flow from the second channel opening to the first channel opening, is arranged in the channel. Arranged on the second channel opening is a shut-off valve, which is forced into a position closing the second channel opening when the rivet snap is in the working position.

    Abstract: The striking pin (16) is arranged in a bearing (29). The striking pin (16) has a circumferential surface (25) and a stop surface (27) facing in the striking direction (11). The bearing (29) has a sleeve (30) arranged coaxially to the working axis (10) as well as a catcher (32). The circumferential surface (25) of the striking pin (16) is installed so as to slide on the inside of the sleeve (30). The catcher (32) is arranged in the striking direction (11) of the stop surface (27) of the striking pin (16) in order to limit the movement of the striking pin (16) in the striking direction (11). A connecting link (35) is provided for purposes of causing the striking pin (16) to execute a rotation relative to the bearing (29) when the striking pin (16) moves in the striking direction (11). The connecting link (35) has a flank (42; 53) on the striking pin (16) and another flank (49; 52) on the bearing (29), whereby the two flanks (42; 53, 49; 52) that rest against each other during the movement rise in the striking direction (11) in the same circumferential direction (39).
