  • the guide tube has an exciter section, in which the exciter element is guided, with a first inner diameter and an anvil section adjoining the Ereger section, which receives the pot section of the striker, with a second inner diameter.
  • the first seal is arranged on the inside of the dowel section of the guide tube near the transition to the exciter section.
  • the pot portion has a pot inside, in which the percussion piston is completely absorbable, or whose axial length is at least as large as the axial length of the percussion piston.
  • the pot chamber has a diameter which corresponds to the first inner diameter of the exciter section, whereby the percussion piston during its oscillating stroke movement during operation of the impact mechanism with the air spring switched between the pot and the exciter section of the guide tube can move back and forth.
  • the striker has an axially extending elongate extension on which the annularly shaped percussion piston is guided axially displaceable and forms at its end facing the excitation element a valve portion as a shut-off, with a vent enclosing annular part of the Excitation element cooperates.
  • a first seal of the valve between the valve portion of the striker and the annular portion of the excitation element is provided.
  • About the seal lying between the exciter element and the percussion piston space for switching on the air spring is sealed against the arranged in the annular part of the exciter element ventilation opening of the valve.
  • the first seal is arranged radially inward on the annular part.
  • FIG. 1 is a designed as a rotating and hammering combi hammer hand tool 10 reproduced, which has a housing 11 in which a on a can be arranged in a tool holder 14 tool 15 striking mechanism 20, a transmission 13 and a motor 12 are arranged.
  • the impact mechanism 20 is coupled via an output shaft 16 to the transmission 13, which translates a rotational movement of the motor 12.
  • the striking mechanism 20 has a guide tube 21, in which a exciter element 22 designed as an exciter piston is guided to be moved back and forth.
  • the guide tube 21 may be designed to simplify the Monday two or more parts.
  • the excitation element 22 is connected to generate a lifting movement during operation of the power tool 10 via a pivotally mounted on this connecting rod 29 with an eccentric 17 on the output shaft 16 of the transmission 13.
  • a cup-shaped stopper 24 is further mounted axially displaceable, in the pot chamber 34, a percussion piston 23 is guided axially movable.
  • the percussion piston 23 and the pot chamber 34 of the striker 24 are dimensioned so that the percussion piston 23 can be completely absorbed in the pot chamber 34, as in Fig. 2 you can see.
  • the striker 24 has a percussion piston 23 facing away from the impact end 30, via which it can act on the plugged into the tool holder 14 tool 15 striking.
  • an air spring 25 is switched on and switched off.
  • the striker 24 form a valve 26 remote from the striking end 30 and the guide tube 21 in the region of a first seal 27 arranged between the guide tube 21 and the valve section 36, wherein the striker 24 with its valve section 36 serves as a shut-off member of the valve 26 acts.
  • ventilation openings 35 through which air can escape from the space between the excitation element 22 and the percussion piston 23 in the space outside the guide tube 21 when the valve is open (see. Fig. 3 ).
  • the diameter D T of the pot chamber 34 corresponds to the inner diameter D I1 of an exciter section 21a of the guide tube 21 in which the exciter element 22 is located, so that the percussion piston 23 in the operation of the percussion mechanism 20 at active or switched-air spring 25 can move into the exciter section 21a of the guide tube 21.
  • a the exciter section 21 a averted striker section 21 b of the guide tube 21 has a larger inner diameter D I2 than the exciter section 21 a, so that the pot portion 39 of the striker 24 in the guide tube 21 while maintaining the condition that the diameter D T of the pot chamber 34 equal the inner diameter D I1 , can be recorded.
  • At least one circumferential second seal 28 is arranged on the percussion piston 23 and serves for sealing against the inner surface of the pot portion 39 of the striker 24 or against the inner surface of the exciter portion 21a of the guide tube 21.
  • the excitation element 22 also has at least one annular third seal 37, which seals it against the inner surface of the exciter section 21a of the guide tube 21.
  • second vent holes 32 are mounted in the end portion of the pot portion 39 facing the striking end 30, which communicate with first ventilation holes 31 in the guide tube 21.
  • Fig. 2 is the hand tool 10 off Fig. 1 in operation with the arranged in the tool holder 14 tool 15 to a workpiece (not darg Hor) pressed.
  • the striker 24 is in its maximum position retracted far into the guide tube 21 in the direction of the exciter element 22.
  • the valve 26 is closed because the valve portion 36 of the striker 24 sealingly abuts the first seal 27, so that the space between the excitation element 22 and the percussion piston 23 does not communicate with the ventilation openings 35.
  • the air spring 25 is active or turned on and the striking mechanism 20 operates normally.
  • Fig. 3 is the hand tool 10 off Fig. 1 not pressed against a workpiece during operation with the tool 15 arranged in the tool holder 14.
  • the striker 24 is in its tool 15 facing the end position.
  • the valve 26 is opened because the valve portion 36 of the striker 24 has moved away from the first seal 27, so that the space between the excitation element 22 and the percussion piston 23 communicates with the ventilation openings 35.
  • the air spring 25 between the excitation element 22 and the percussion piston 23 is inactive or switched off.
  • the striking mechanism 20 works in the empty space, since the percussion piston 23 can no longer be sucked in and no longer exerts blows on the tool.
  • Fig. 4 is a further embodiment of an inventive impact mechanism 20 of a hand tool 10 ( Fig. 1 ).
  • the impact mechanism 20 in turn has a guide tube 21, in which a excitation element 22 designed as an excitation piston is guided to be movable back and forth.
  • the excitation element 22 is connected to generate a lifting movement during operation of the power tool 10 via a pivotally mounted on this connecting rod 29 with an eccentric 17 on the output shaft 16 of the transmission 13.
  • a striker 24 is mounted axially displaceable, which has an elongated rod-shaped extension 40 which forms at its end portion facing the exciter element 22 designed as a shut-off valve portion 36 of a valve 26.
  • the percussion piston 23 is annular and is displaceable with a second annular seal 28 on the cylindrical surface of the extension 40 at.
  • a fourth circumferential seal 38 is arranged, which seals the percussion piston 23 against the inner wall of the guide tube 21.
  • the exciter element 22 has an annular part 22a, which has an inner annular first seal 27, and a radially outer third seal 37th
  • the excitation element 22 with its annular opening, which acts as a vent opening 35 and which cooperates with the valve portion 36 of the striker 24 , as well as the first seal 27 are also part of the valve 26th
  • FIG. 4 the anvil 24 is shown in a first position (solid lines), in which it has retracted maximally far into the guide tube 21 in the direction of the exciter element 22, since the handheld power tool 10 (FIG. Fig. 1 ) with the tool 15 to a workpiece (not shown) is pressed.
  • the valve 26 is closed because the valve portion 36 of the striker 24 sealingly abuts the first seal 27 in the vent 35 in the excitation element 22 and closes it.
  • the air spring 25 between the percussion piston 23 and the excitation element 22 is active or turned on and the striking mechanism 20 operates normally.
  • FIG. 4 the anvil 24 is also shown in its tool receiving end position (dashed lines), which it assumes when the hand tool 10 ( Fig. 1 ) is not pressed against a workpiece during operation with the tool.
  • the valve 26 is opened because the valve portion 36 of the striker 24 is moved away from the first seal 27 and the ventilation opening 35 in the excitation element 22 so that the space between the excitation element 22 and the percussion piston 23 can communicate with the ventilation opening 35.
  • the air spring 25 between the excitation element 22 and the percussion piston 23 is inactive or switched off.
  • the Schlagtechnik 20 works in the Blank, since the percussion piston 23 can no longer be sucked in and exerts no impact on the tool in the tool holder.
