Flow control device and flow control method for construction machine
A flow control device for a construction machine including a first hydraulic cylinder and a second hydraulic cylinder connected to a hydraulic pump, which is connected to an engine. A first control valve and a second control valve are also included. A regeneration flow path is configured to supplement and reuse hydraulic fluid that returns to a hydraulic tank during a retractable drive of the first hydraulic cylinder. A regeneration valve is installed in the regeneration flow path. A pressure compensation type flow control valve is installed in a meter-in flow path of a spool of the first control valve, and is configured to limit the flow rate of the hydraulic fluid supplied from the hydraulic pump to the first hydraulic cylinder during a combined operation of the first and second hydraulic cylinders.
