  • Hydraulic cylinder assembly and method for operating a hydraulic cylinder assembly
    Patent number: 12768374
    Abstract: A hydraulic cylinder assembly includes a hydraulic cylinder, a motor for driving an adjustable pump, the pump, and a pivot angle control system for the pump. The pivot angle control system has at least one adjustment piston for adjusting the pump and an electrically controllable valve for controlling the adjustment piston. At least one conveying direction of the pump and thus a movement of the hydraulic cylinder is controllable via the pivot angle control system. The hydraulic cylinder assembly further includes an electrical control unit for operating at least the motor and the valve and an uninterruptible power supply, configured such that, in the event of a failure of a power supply for the control unit, at least the control unit can be supplied with electrical power from the uninterruptible power supply.
