Inclined rotation control device of variable displacement hydraulic pump

摘要

A motion converting section ( 31 ) and a translation bar ( 33 ) of a feedback mechanism ( 30 ) are provided between a lateral side of a swash plate ( 21 ) and a control sleeve ( 26 ) of a regulator ( 24 ). When the swash plate ( 21 ) is in a neutral position, the motion converting section ( 31 ) is located in an initial position (F-F) at one end of axial direction along an axis line (O-O) passing through a tilting center (C) of tilting motions, and, when the swash plate ( 21 ) is driven to tilt in a forward or reverse direction, displaced to the other end of axial direction along the axis line (O-O) to convert a tilting motion of the swash plate ( 21 ) into an axial displacement. Through the translation bar ( 33 ), the axial displacement is transmitted to the control sleeve ( 26 ) of the regulator ( 24 ) as an axial displacement.
