PURPOSE:To simplify the structure of the control in the caption and improve its reliability, by feeding discharged oil from a pump to the primary and secondary side pulleys via a distributing valve and providing each feed piping with the 1st and the 2nd pressure regulating valves. CONSTITUTION:An oil pump 42 is connected to the primary side hydraulic cylinder 26 of the primary side variable pulley 20 and the secondary side hydraulic cylinder 28 of the secondary side variable pulley 22, via a distributing valve 44, the 1st line oil passage 62, and the 2nd line oil passage 64, with the 1st line oil passage 62 and the 2nd line oil passage 64 provided with the 1st pressure regulating valve 68 and the 2nd pressure regulating valve 70 respectively. Hence, transmission control can be performed by simply regulating the 1st line oil pressure Pl1 and 2nd line oil pressure Pl2, then no transmission control valve is required, the structure of a control is simplified and the reliability is improved. |
