Control device for hydraulic drive system, has load-compensating unit with flow sensor to determine actual flow of pressurized fluid flowing to associated actuator, where flow sensor and inlet throttle are connected in control device

摘要

The control device (20) has an adjustable inlet throttle (21) to control the flow of a pressure fluid, while multiple actuators (11) and a pump (12) is provided to promote the pressure fluid to the actuators. A load-compensating unit of each actuator is provided with a flow sensor (23) to determine the actual flow of the pressurized fluid flowing to the associated actuator. The flow sensor and the inlet throttle are connected in the control device. The control device is arranged so that the inlet throttle is adjusted depending on the associated target flow and the associated actual flow.
