用于控制工程机械的再生流量的装置及其控制方法
摘要：
公开一种用于控制工程机械的再生流量的装置及其控制方法，该装置能够将在斗杆缩进驱动期间从斗杆油缸排放至工作油箱的工作油的一部分供应到斗杆油缸的较大腔室并对其进行再生。本发明提供了一种用于控制工程机械的再生流量的装置，该装置的特征在于包括：可变容量型液压泵和先导泵；斗杆油缸，通过液压泵供应的工作油驱动；可变斗杆再生阀，安装在斗杆油缸和工作油箱之间的路径中；电子比例阀，安装在先导泵和斗杆再生阀之间的路径中。
摘要（英）：

Disclosed are a device for controlling a regenerated flow rate for a construction machine and a method for controlling the same, the device being able to supply a large chamber of an arm cylinder with a part of operating oil, which is discharged from the arm cylinder to an operating oil tank during arm-in driving, and regenerating the same. The present invention provides a device for controlling a regenerated flow rate for a construction machine, the device being characterized by comprising: a variable capacity-type hydraulic pump and a pilot pump; an arm cylinder driven by operating oil supplied from the hydraulic pump; a variable arm regeneration valve installed in a passage between the arm cylinder and the operating oil tank; and an electronic proportional valve installed in a passage between the pilot pump and the arm regeneration valve.
