    • A hydraulic control apparatus including a gain switch section switching a gain of a line pressure adjustment valve between a first range gain that is less than 1 and a second range gain that is greater than or equal to 1, and a source pressure switching valve switching a source pressure for a working pressure adjustment valve that outputs the control pressure for the line pressure adjustment valve between the line pressure and a modulator pressure is disclosed. The source pressure switching valve switches the source pressure for the working pressure adjustment valve to the line pressure when the gain switching section switches the gain of the line pressure adjustment valve to the first range gain, and switches the source pressure for the working pressure adjustment valve to the modulator pressure when the gain switching section switches the gain of the line pressure adjustment valve to the second range gain.
    • 一种液压控制装置,包括增益开关部分,其切换小于1的第一范围增益和大于或等于1的第二范围增益之间的管线压力调节阀的增益,以及源压力切换阀切换 公开了用于在管路压力和调节器压力之间输出管路压力调节阀的控制压力的工作压力调节阀的源压力。 当增压切换部将线压调节阀的增益切换到第一范围增益时,源压力切换阀将工作压力调节阀的源压力切换为管路压力,并切换工作压力调节阀的源压力 当增益切换部分将线路压力调节阀的增益切换到第二范围增益时,到调制器压力。
