Abstract

PURPOSE:To simplify a control system by providing a spring energizing a spool at the position communicating a friction element and a hydraulic source and a hydraulic passage facing it and applying a larger force to the spool and giving the shift valve function to a relief valve. CONSTITUTION:A spool 201 is energized by a spring 205 to communicate an output port 202 communicated to an oil path 141 on a 3-4 clutch 27 side and an input port 203 communicated to an oil path 142 on a hydraulic source side. A pressure receiving section 211 is provided on the spool 201, and the fixed oil pressure from a solenoid reducing valve 44 is applied to generate the opposed force larger than the load of the spring 205. A relief valve 50 can thereby have the fail-safe function, the off function, and the shift valve function, and the structure of a hydraulic control system can be simplified.
