Patent number: 11738440Abstract: A portable, battery-powered hydraulic unit for hydraulic rescue tools, in particular for spreading or cutting tools, as well as a rescue tool equipped therewith, are disclosed. The hydraulic unit includes at least one hydraulic pump, a hydraulic tank, a compensation device for hydraulic fluid, a manually operated hydraulic control valve, an electromechanical interface for on-demand coupling and decoupling of at least one battery pack, a mechanical-hydraulic interface for connecting a hydraulic tool, and an electric motor operable by the electrical energy of the battery pack for driving the hydraulic pump. The electric motor is formed by a disc-shaped motor whose axial length extending in parallel to the longitudinal axis of its output shaft is shorter than its outer diameter.Type: GrantFiled: February 1, 2022Date of Patent: August 29, 2023Assignee: Weber-Hydraulik GmbHInventors: Johann Schmollngruber, Dominik Steinparzer
