【発明の名称】油圧ポンプの吐出流量制御装置及び方法
Document Type and Number:
Japanese Patent JP2807751
Kind Code:
B2
Abstract:
A discharge flow control system and method of a hydraulic pump driven by an engine for the minimization of the difference between a discharge amount of flow in the pump and total amount of operating oil necessary to operate each actuator in hydraulic equipment. The control system is provided with a detector which detects the number of rotation of the engine, generates equal number of pulses to the number of rotation, a detector which detects the tilt angle of a swash plate of the pump, a detector which detects the operating displacement of the actuator, a detector which detects the load pressure acting on the pump, and a controll unit which controls a target discharge flow amount of the pump which is suitable for performing a predetermined work based on the number of rotation, the tilt angle, the displacement and the load pressure.
