摘要： An improved impact power tool for carving and engraving an article comprises an air delivery system operable to communicate with a pressurized air source; a drive assembly operable to receive air from the pressurized air source via the air delivery system; a hand held device in driven communication with the drive assembly; and a housing for storage of the air delivery system and drive assembly. The tool includes an improved valve design, a throttle bias valve, and an air storage tank housed within the housing, and an improved housing construction. The improved valve design and air storage tank enable greater stroke speeds of a work tool over a wider power range while also improving the crispness and speed of the impact reaction time over the entire range. The throttle bias valve is in communication with an additional exhaust path, such that the bias valve allows improved control of the hand held device and improved operation over a wider range of air pressures.

摘要： It is an object of the present invention to provide a vibration reducing technique caused by air pressure fluctuations within a power tool. According to the present invention, a representative power tool may comprise a driving motor, a driver and a tool bit. The driving motor drives the driver to cyclically reciprocate. The tool bit is linearly driven by utilizing the pressure of air within the power tool. The air may be compressed by the reciprocating movement of the driver. The power tool changes the rotational speed of the driving motor in the cycle of the reciprocating movement of the driver so that vibration caused in the power tool can be alleviated.

摘要： A method for the open-loop and closed-loop control of a power tool, in particular a chipping hammer, containing a drive, a control device, a sensor, a transmission and a handle apparatus. The handle apparatus contains a lever element with a signal transmitter and pivotable relative to the sensor. A first and second position of the signal transmitter are sensed by the sensor, wherein the distance between the first and second position corresponds to a first distance. The difference between a maximum distance of the lever element and the first determined distance is determined. A first rotational speed for the drive is set when the determined difference between the maximum distance of the lever element and the first determined distance corresponds at least to a first predetermined threshold value. A second rotational speed for the drive is set after the second position has been reached and after a predetermined period of time has elapsed.

摘要： A hammer drill having an impact mechanism and a rotary drive, wherein the hammer drill is designed to rotate a tool at a speed n about a longitudinal axis of the tool and to drive it with an output impact power PS along the longitudinal axis with a striking movement is disclosed. At a working point, at least one condition is met: 1. The ratio of the output impact power PS to the speed n is at least 3.5 W/rpm; 2. Depending on the output impact power PS, the speed n is at most (PSAN−300)2/2000+150) rpm; 3. In the event of an infinitesimal change in the output impact power PS, the speed n changes by at most 0.1 rpm/W.
