发明名称 HYDRAULIC PRESSURE SUPPLY UNIT OF CONTINUOUSLY VARIABLE TRANSMISSION
摘要 A control valve switches between the (A) state where the first oil passage to which a hydraulic pressure obtained by decreasing a line pressure is supplied is in communication with the fifth oil passage for supplying the hydraulic pressure to a forward clutch or a reverse brake and the third oil passage to which a hydraulic pressure controlled by an SLP linear solenoid valve is supplied is in communication with the sixth oil passage for supplying the hydraulic pressure to a primary pulley, and the (B) state where the second oil passage to which a hydraulic pressure controlled by an SLT linear solenoid valve is supplied is in communication with the fifth oil passage and the fourth oil passage for supplying the hydraulic pressure to a secondary pulley is in communication with the sixth oil passage. The fourth oil passage has an orifice.
