AI Technical Summary
Technical Problem
In machinery using pressure-operated actuators, back pressure can lead to unnecessary energy consumption or insufficient control accuracy under different operating conditions, especially when operating on slopes.
Method used
By adjusting the pressure and volumetric flow rate on the actuator's return line, and based on the position and motion state of the structural components of the working machinery, the back pressure is dynamically adjusted using detection and control devices to ensure operational accuracy and optimal energy consumption.
Benefits of technology
It enables precise control of the operation of machinery under different usage conditions, reduces energy consumption, and improves control performance in high-dynamic-characteristic motion.

Abstract
A working machine (1) includes at least one structural element (21), at least one pressure medium-operated actuator (22) for establishing at least one operation of the working machine, and at least one detection device (23) for determining the position of the structural element (21). An arrangement for controlling at least one operation of the working machine (1) includes: a control valve device (24) for controlling the actuator (22), and a control device (25) for controlling the control valve device (24). The control device (25) is adapted to control the control valve device (24) to regulate the pressure and / or volumetric flow rate on the return line of the actuator (22) according to the position of the structural element (21).
