PROBLEM TO BE SOLVED: To provide a fluid pressure generator and a spool position estimation device that have improved responsiveness of a spool valve.SOLUTION: A fluid pressure generator is provided with a regulator 15a including a cylinder body 15a1, a spool 15a2 that slides in the cylinder body 15a1, a pilot room R11 into which a pilot pressure, which is a fluid pressure for moving the spool 15a2 along an axial direction, is input, and an output room R12 from which an output pressure, which is a fluid pressure according to the pilot pressure, is output. The fluid pressure generator also includes: a spool position acquisition part 17c for acquiring a relative position of the spool 15a2 with respect to the cylinder body 15a1; and a pilot pressure control part 17d for controlling the pilot pressure based on the relative position acquired by the spool position acquisition part 17c.SELECTED DRAWING: Figure 2

    【課題】スプール弁の応答性を向上させた液圧発生装置およびスプール位置推定装置を提供する。【解決手段】液圧発生装置は、シリンダボディー15a1と、シリンダボディー15a1内を摺動するスプール15a2と、スプール15a2を軸方向に沿って移動させる液圧であるパイロット圧が入力されるパイロット室R11と、パイロット圧に応じた液圧である出力圧が出力される出力室R12と、を有して構成されたレギュレータ15aを備えている液圧発生装置であって、スプール15a2のシリンダボディー15a1に対する相対位置を取得するスプール位置取得部17cと、スプール位置取得部17cによって取得された相対位置に基づいて、パイロット圧を制御するパイロット圧制御部17dと、を備えている。【選択図】 図2
