摘要
PURPOSE: A flow rate control apparatus of a hydraulic pump using a relief valve is provided to improve energy efficiency by reducing flow rate through the relief valve as preventing the generation of overload in a hydraulic system. CONSTITUTION: According to the flow rate control apparatus, a variable hydraulic pump(1) is connected to an engine. A hydraulic cylinder(8) and a rotation motor(5) are connected to the hydraulic pump and are driven when operation oil is supplied. Control valves(3,4) controls the operation oil flow direction by being switched when pilot signal pressures are applied. A regulator(2) and a controller(9) control swash plate displacement of the hydraulic pump.
