ABSTRACT:
A hydraulic control device for use with an automatic speed change gear device for a diesel engine using a torque convertor and an auxiliary speed change gear device. This hydraulic control device is provided with a back pressure control valve controlled by means of a throttle pressure developed in response to a throttle opening, wherein when the throttle opening is smaller than a given opening, a pressure oil having a pressure lower than a line pressure is introduced to an accumulator, and when the throttle opening is greater than the aforesaid given opening, a pressure oil having the same pressure level as that of said line pressure is fed to said accumulator to thereby obtain a desired engaging pressure for said automatic speed change gear device, thus effectively preventing a shock due to a change in speed. This device may also be used with a gasoline engine.
