摘要： A pneumatic impulse wrench for tightening screw joints includes a housing with a pressure air inlet passage, an exhaust air outlet passage, a rotation motor, a hydraulic impulse generator, and is connected to a stationary programmable control unit. The impulse wrench also includes a torque indicating mechanism connected to the control unit for feeding back electric signals responsive to the output torque of the wrench, an electromagnetically activated inlet valve arranged in the air inlet passage, and an electromagnetically activated exhaust valve which controls the exhaust air flow from the motor. The exhaust valve is a proportional valve activated by a linearly operated electromagnetic actuator and arranged to continuously adapt the exhaust air flow and, hence, the motor power to the characteristics of the actual screw joint being tightened in response to feed back signals from the torque indicating mechanism and in accordance with a programmed tightening strategy.

摘要： A power tool has a housing, a pneumatic rotation motor supplied with pressure air via an inlet passage, an outlet passage connecting the motor to an exhaust air discharge, and a speed governor for controlling the pressure air flow through the inlet passage responsive to the motor speed. The outlet passage includes a first outlet duct and a second outlet duct extending in parallel between the motor and exhaust air discharge, and an exhaust valve which controls exhaust air flow through the second outlet duct. The exhaust valve is spring biased toward a closed position and shifted to an open position by an activator which is exposed to the air pressure in the inlet passage downstream of the speed governor and which shifts the exhaust valve to the open position at pressure levels above a certain pressure level in the inlet passage downstream of the speed governor.
