摘要： A power tool is disclosed. The power tool has a striker, which is guided along an axis in a guide tube. A pneumatic chamber has a volume which varies with a movement of the striker. The pneumatic chamber is closed by the striker, the guide tube and a valve device. The valve device has in a flow channel a sealing element that is moveable between two positions in a bearing along the axis. The flow channel has a first cross-sectional area in a first of the two positions of the sealing element adjacent to a first mating surface of the bearing, and the flow channel has a second cross-sectional area in a second of the two positions of the sealing element adjacent to second mating surface of the bearing offset from the first mating surface along the axis. The second cross-sectional area is greater than the first cross-sectional area.

摘要： A power tool and control method is disclosed. The power tool has a striker, which is guided along an axis parallel to an impact direction. A pneumatic chamber has a volume which varies with a movement of the striker along the axis. A valve device that is actuatable depending upon the movement direction of the striker connects the pneumatic chamber with an air reservoir. The valve device is actuated to open in the case of a movement of the striker in the impact direction and in the case of a movement of the striker against the impact direction is actuated to throttle or close. The throttled or closed valve device restricts an air flow flowing through it to a maximum of one tenth of the value as compared to the air flow in an opened position.

摘要： A power tool is disclosed. The power tool includes a striker, a guide tube in which the striker is guided along an axis, and a pneumatic chamber, which is closed by the striker, the guide tube and a valve device actuated by its own medium. A volume of the pneumatic chamber changes in the case of a movement of the striker along the axis. The valve device has a swivelable sealing element between the striker and the guide tube. The swivelable sealing element is swiveled into a retracted position when the striker moves in the impact direction and is swiveled into an extended position when the striker moves against the impact direction. In the retracted position, the sealing element has a first inflow surface. In the extended position, the sealing element has a second inflow surface. The second inflow surface is larger than the first inflow surface.
