| 摘要 |
The invention relates to a hand tool (10), comprising a housing (12), a rotor (32), which is rotatably mounted in the housing (10) and non-rotatably coupled to a tool holder (14), a valve (45), which is equipped to control a supply of a pressure fluid driving the rotor (32), a brake, which is equipped to decelerate the rotor (32), and an actuating element, which is equipped to actuate the valve (45) and the brake in a coordinated manner such that the brake decelerates the rotor (32) in a closed position of the valve (45) which interrupts the supply of the pressure fluid. The hand tool (10) is characterized in that the actuating element is a rotatable control sleeve (18), which is equipped to control the brake and the pressure fluid supply in a coordinated manner such that the valve (45) is opened at the same time as the brake is released, and wherein a characteristic brake-adjustment travel-rotary angle curve (114) of the control sleeve (18) in a first rotary angle range in the vicinity of the closed position of the control sleeve (18) is steeper than in a second rotary angle range further removed from the closed position. |
