Abstract: A power tool includes a housing, a motor positioned within the housing, and an impulse assembly coupled to the motor to receive torque therefrom. The impulse assembly includes a cylinder at least partially forming a chamber containing a hydraulic fluid, an anvil positioned at least partially within the chamber, and a hammer positioned at least partially within the chamber. The hammer includes a first side facing the anvil and a second side opposite the first side. The impulse assembly further includes a biasing member biasing the hammer towards the anvil, and a valve movable between a first position that permits a first fluid flow rate of the hydraulic fluid in the chamber from the second side to the first side, and a second position that permits a second fluid flow rate of the hydraulic fluid in the chamber from the first side to the second side.

Abstract: A powered fastener driver includes a driver blade movable from a top-dead-center position to a bottom-dead-center position for driving a fastener into a workpiece, a drive unit for providing torque to move the driver blade toward the top-dead-center position, and a rotary lifter engageable with the driver blade. The rotary lifter having a body and a drive pin coupled to the body. A roller is rotatably coupled to the drive pin and includes a non-cylindrical outer peripheral surface defining a plurality of engagement sections. A tooth of the driver blade is configured to engage one of the engagement sections when moving the driver blade from the bottom-dead-center position toward the top-dead-center position.

Abstract: A power tool includes a housing, a motor positioned within the housing, a controller electrically coupled to the motor, and a transmission coupled to the motor. The transmission includes a ring gear and a torque transducer coupled to the ring gear. The torque transducer is configured to transmit a torque value to the controller. The power tool further including an impulse assembly coupled to the transmission to receive torque therefrom. The controller is configured to receive a target output torque value and to determine an actual output torque based at least in part on the torque value from the torque transducer, and the controller is configured to stop operation of the motor in response to the actual output torque being within a predefined margin of the target output torque value.

Abstract: A powered fastener driver includes a driver blade movable from a top-dead-center (TDC) position to a bottom-dead-center (BDC) position for driving a fastener into a workpiece and a drive unit for providing torque to move the driver blade from the BDC position toward the TDC position. A rotary lifter is engageable with the driver blade and configured to receive torque from the drive unit for returning the driver blade from the BDC position toward the TDC position. The lifter has a body, a drive pin coupled to the body, and a roller positioned on the drive pin. The roller includes an engagement section configured to receive an end portion of a tooth of the driver blade. The lifter includes a means for aligning the engagement section with the end portion of the tooth on the driver blade to facilitate meshing between the end portion and the roller.
