  • Patent number: 11813914
    Abstract: A hydraulic active suspension flow control system includes a hydraulic oil tank, a variable displacement pump with an oil suction port communicating with the hydraulic oil tank, a check valve, a servo valve, a suspension cylinder controlled by the servo valve, an engine revolution speed sensor configured to detect an engine revolution speed, a vehicle speed sensor configured to detect a vehicle speed, an oil pressure sensor configured to detect an accumulator outlet pressure, a flow controller configured to control displacement of the variable displacement pump by receiving data from the engine revolution speed sensor, the vehicle speed sensor and the oil pressure sensor, and a relief valve connected to the check valve in parallel and provided at an oil outlet of the variable displacement pump. The variable displacement pump is connected to an engine through a clutch; and an accumulator is connected between the servo valve and the check valve.
