Patent number: 11958177Abstract: 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.Type: GrantFiled: September 9, 2019Date of Patent: April 16, 2024Assignee: Milwaukee Electric Tool CorporationInventors: James G. Ballard, Timothy Radtke, Daniel Garces, Ian C. Zimmermann

Patent number: 11654590Abstract: An example system includes a cutting tool and a device configured to remotely control the cutting tool. In response to receiving information indicative of actuation of a first user interface item, the device sends a first signal to the cutting tool so as to request enabling the cutting tool to be operated remotely. The cutting tool sends a second signal to the device indicating that remote operation of the cutting tool has been enabled. The cutting tool receives information indicating that the trigger has been activated, and sends a third signal to the device indicating that the cutting tool is ready to perform a cutting operation. The device receives information indicative of actuation of a second user interface item, and responsively, sends a fourth signal to the cutting tool so as to cause the cutting tool to perform the cutting operation.Type: GrantFiled: August 17, 2021Date of Patent: May 23, 2023Assignee: Milwaukee Electric Tool CorporationInventors: Luke J. Skinner, Burtrom L. Stampfl, Timothy J. Bartlett, Carter H. Ypma, Timothy R. Obermann, Benjamin O. Cabot, Kris J. Kanack, Thomas C. Hanks, Ian C. Zimmermann
