<p><P>PROBLEM TO BE SOLVED: To provide a fluid operation type position adjustment device including a servo means. <P>SOLUTION: A supply connecting section 22, a discharge connecting section 23, and a power connecting section 24 are provided adjustably by the servo means 12 arranged in a housing 1 of the adjustment device in a fluid circuit. The servo means 12 for positioning its location has two fluid operating surfaces 15a and 15b which are opposite each other. The fluid operating surfaces are the same size, and can fix boundaries of control chambers 37a and 37b, respectively. The two control chambers are connected with a common control pressure connecting section 52 via choke means 34a and 34b arranged between the control chambers. In downstream of the choke means, respective control chambers are connected with discharge outlets 55a and 55b. A control valve means 16 can control two discharge outlets, and can particularly close both discharge outlets. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
