  • Patent number: 11975436
    Abstract: A power tool includes a housing, a motor supported by the housing, and an output spindle rotatably supported relative to the housing about an axis. The motor is operable to drive the output spindle about the axis. The power tool includes a spindle lock assembly between the motor and the output spindle. The spindle lock assembly is adjustable between an unlocked state in which the output spindle is rotatable relative to the housing about the axis and a locked state in which the output spindle is rotationally fixed relative to the housing. The spindle lock assembly includes a first resilient member, positioned between the housing and the output spindle. The first resilient member is configured to at least partially absorb a torque impulse from the output spindle when rotating in a first direction and when the spindle lock assembly transitions from the unlocked state to the locked state.

  • Patent number: 11958177
    Abstract: A hydraulic pump includes a work port, a high-flow piston, multiple high-pressure pistons, and an unloading valve. The work port couples to a fluid supply line of a hydraulic tool. The high-flow piston supplies fluid along a first flow path to the work port. The high-pressure pistons supply fluid along a second flow path to the work port. The unloading valve is fluidly coupled to the first flow path and the second flow path, and actuatable between an open state and a closed state. The unloading valve is configured to (i) permit fluid to flow from the high-flow piston to the work port in the open state, (ii) inhibit fluid from flowing from the high-flow piston to the work port in the closed state, and (iii) actuate from the open state to the closed state when a pressure of the fluid in the second flow path exceeds a threshold pressure.
