Abstract

PURPOSE: To obtain arbitrary valve sensitivity characteristics, by providing a potentiometer that generates electric signals in accordance with angles of torsion of a torsion bar to control a servo motor, which controls a hydraulic control valve, by the output of the potentiometer.
CONSTITUTION: When displacement of a rotational angle occures between a worm shaft 2 and an input shaft 3, a nut plate 6 is moved in the axial direction so that the angle of torsion of the torsion bar 4 is detected. According to this displacement of the angle of torsion, an operation shaft 11 of the potentiometer 10 is moved, and using its output the rotational position of the servo motor 17 is controlled. By the rotational operation of the servo motor the control valve 15 is displaced, and the pressurized oil generated by a hydraulic pump is allowed to be introduced into a cylinder chamber to assist the powering.
