Abstract

PURPOSE: To make the promotion of miniaturization and light weight for the overall device, by feeding a line pressure in the band servo tightening side to the direct- couple clutch through a direct-coupled control valve controlled by a governor pressure.
CONSTITUTION: When reaching an up prescribed value at second speed, a governor pressure exceeds the prescribed value to press shift a spool 13a against the tension of spring 13b, and a direct-coupled control valve 13 is closed, and a line pressure, fed to a tightening side 16a of the band servo, passes a path 14a from the direct- coupled control valve 13, being fed to an oil pressure room 8, with a piston 9 pressing a cluth disk 6 to a pressure plate 10, to provide a direct-coupled state. For operating oil pressure of the direct-coupled clutch is directly used the line pressure much higher than the governor pressure, capable of lessening oil pressure bearing area of the direct-coupled clutch, and making the promotion of miniaturization and light weight for the whole unit of device.
