Abstract: An impact power tool includes a transmission output shaft, a rotary impact assembly with a cam shaft, hammer, and anvil, and a tool output shaft rotatable with the anvil. A coupler removably couples the cam shaft to the transmission output shaft. When torque on the tool output shaft is less than or equal to a first threshold, the transmission output shaft, cam shaft, hammer, and anvil rotate together to transmit torque to the tool output shaft. When torque on the tool output shaft is above the first threshold, the hammer moves along the cam shaft away from the anvil by a first distance and applies rotary impacts to the anvil. When the hammer moves along the cam shaft away from the anvil by a second distance greater than the first distance, the coupler decouples the transmission output shaft from the cam shaft, interrupting torque transmission to the tool output shaft.

Abstract: A power tool comprises a housing, a motor assembly and an impact assembly configured to be driven by the motor assembly. The impact assembly comprises a hammer defining a hammer chamber therein and an anvil at least partially disposed in the hammer chamber and configured to rotationally drive an output shaft. The anvil comprises a body portion, an anvil chamber defined therein, and a reciprocating member configured to selectively move radially outwardly relative to the body portion to be selectively impacted by an impact member of the hammer so that the hammer selectively imparts rotational movement to the anvil. The anvil includes an active valve configured to control discharge of fluid from an anvil chamber to the hammer chamber. The active value variably opens based on variance of one or more physical characteristics of the fluid (e.g., at least one of volume, temperature, pressure, or viscosity of the fluid).

Abstract: An actuator assembly for a power tool includes an actuator with a permanent magnet. The actuator is moveable between a first position for a first mode of operation, and a second position for a second mode of operation. A first positioning member is adjacent the first position composed of a ferromagnetic material to attract the permanent magnet. A second positioning member is adjacent the second position and composed of a ferromagnetic material to attract the permanent magnet. An electromagnet may be energized to move the actuator between the first position and the second position. When the electromagnet is not energized and the actuator is in the first position, the actuator is retained in the first position. When the electromagnet is not energized and the actuator is in the second position, the actuator is retained in the second position. When the electromagnet is energized, the actuator moves between the first and second positions.
