LUBRICATION APPARATUS FOR AUTO TRANSMISSION

摘要

PURPOSE: A lubricating apparatus for an auto transmission is provided to supply lubricating oil enough without increasing the cavity of an oil pump and to increase feeding pressure of the lubricating oil by supplying working fluid to a lubricated member. CONSTITUTION: A first feeding port(152a) supplies working fluid passing through a damper clutch control valve to a lubricated member. A second feeding port(154a) supplies the working fluid passing through a torque converter control valve to the lubricated member. The torque converter control valve controls the working pressure of the working fluid provided to the damper clutch control valve. A pressure control valve controls the pressure of the working fluid provided to the torque converter control valve and the damper clutch control valve. A subsidiary feeding port(172) supplies the working fluid which is discharged from the pressure control valve to the lubricated member.
