<p><P>PROBLEM TO BE SOLVED: To provide a pressure adjustment device independent of continuous driving of a power-driven hydraulic pump, and outputting a desired optional oil pressure value with slight control operation force. <P>SOLUTION: The pressure adjustment device includes a static pressure conversion and adjustment mechanism for converting a supply oil pressure to an optional output oil pressure, a hydraulic thrust generation mechanism element for generating hydraulic thrust in a direction opposed to movement force generated in a conversion ratio control member of the static pressure conversion and adjustment mechanism along with in/out behavior of output oil, a multi-stage oil pressure ratio conversion mechanism for static-pressure-converting the supply oil pressure to the multi-stage control oil pressure along with in/out behavior of the output oil, and an oil pressure circuit for offsetting movement force variation generated in the conversion ratio control member by introducing the multi-stage control oil pressure of the multi-stage oil pressure ratio conversion mechanism to the hydraulic thrust generation mechanism element. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
