发明名称 ベルト式無段変速機の油圧制御装置
摘要 A hydraulic control system stably controls pressure in a hydraulic chamber of a pulley accommodating a belt by controlling a feeding valve and a discharging valve. The control system reduces a control amount of the feeding valve to be smaller than that calculated based on a pressure difference in a case other than one in which pressure in the hydraulic chamber is increased by delivering oil to another chamber, in case the pressure in the hydraulic chamber is increased by delivering the oil to the other chamber. The control system reduces a control amount of the discharging valve to be smaller than that calculated based on the pressure difference in a case other than one in which pressure in the hydraulic chamber is lowered by discharging the oil from the other chamber, in case the pressure in the hydraulic chamber is lowered by discharging the oil to the other chamber.
