Abstract
PURPOSE: To simplify machining and reduce cost by constituting the oil hydraulic pressure circuit so that the constitution of the valve spool of the throttle valve can be simplified.
CONSTITUTION: A primary regulator valve to control a line pressure corresponding to the stage of change gear or the degree of opening of the throttle valve by pushing a spool 410 by the throttle pressure on one land of a plunger 310 when advancing, and by pushing the spool by the line pressure applied to other land having a different diameter in addition to the above described pressure when backing, and a throttle valve 400 having 2 lands of the same diameter to control the throttle pressure corresponding to the stroke of an indicator valve 420, are provided. The 1-2 shift valve 500 switches oil passage so that throttle pressure is applied on other lands only at the first speed.
