圧ポンプの制御回路。 In a control circuit for a hydraulic pump in which a variable displacement pump is connected to a load via a switching operation valve, and the discharge pressure from the pump is guided to a regulator so that the discharge amount is decreased as the discharge pressure increases, another method is provided. Hydraulic pressure from a hydraulic source is guided to the regulator via a switching valve, and the switching valve is linked with the switching operation valve to communicate the hydraulic pressure source and the regulator at a neutral position of the switching operation valve. Hydraulic pump control circuit.
