PURPOSE:To improve control response property while compacting the device by internally setting up a phase-angle converter and a hydraulic pump device directly operating the converter into an input shaft formed cylindrically. CONSTITUTION:A slider 4, an operating piston 4e and splines 3a... forming the phase-angle converter converting the phase angle of an output shaft 3 and the hydraulic pump 7 operating the converter are mounted internally into the input shaft 2 formed cylindrically. In such constitution, the hydraulic pump 7 is driven by the input shaft 2 through gears 2c, 7b, the slider 4 is moved through the piston 4e by the pressure oil, and the phase of the output shaft 3 is converted. Response property is improved without generating play because the piston 4e is formed integrally with the slider 4, and axial length can be formed in short size because the hydraulic pump 7 is driven directly by the input shaft 2. |
