PURPOSE:To make a hydraulic control device to a compact size and a light weight by interposing a relief escape valve between an anchor portion 42 and a servo portion 43, and disposing an orifice 54 between the espace valve and an oil pressure supply source. CONSTITUTION:A relief escape valve 51 is interposed between an anchor portion 42 and a servo portion 43, and an orifice 54 is disposed between the escape valve 51 and an oil pressure supply source. This arrangement can eliminate the need of a conventional large-flow regulator valve, and further though a conventional escape valve needs nine elements, the relief type escape valve 51 may do with seven elements. Thus, the device can be made to a compact size and a light weight. |
