Title (EN) HYDRAULIC PRESSURE GENERATION DEVICE AND SPOOL POSITION ESTIMATION DEVICE
(FR) DISPOSITIF DE GÉNÉRATION DE PRESSION HYDRAULIQUE ET DISPOSITIF D'ESTIMATION DE POSITION DE TIROIR CYLINDRIQUE
(JA) 液圧発生装置およびスプール位置推定装置
Abstract:
(EN) A hydraulic pressure generation device with improved spool valve responsiveness and a spool position estimation device are provided. The hydraulic pressure generation device is equipped with a regulator 15a comprising: a cylinder body 15a1; a spool 15a2 which slides inside the cylinder body 15a1; a pilot chamber R11 into which a pilot pressure is input as a hydraulic pressure for causing the spool 15a2 to move along an axial direction; and an output chamber R12 from which an output pressure is output as a hydraulic pressure in accordance with the pilot pressure. The hydraulic pressure generation device is equipped with: a spool position acquisition part 17c for acquiring a relative position of the spool 15a2 to the cylinder body 15a1; and a pilot pressure control part 17d for controlling the pilot pressure on the basis of the relative position acquired by the spool position acquisition part 17c.
(FR) L'invention concerne un dispositif de génération de pression hydraulique, dont la sensibilité à un distributeur à tiroir cylindrique est améliorée, et un dispositif d'estimation de position de tiroir cylindrique. Le dispositif de génération de pression hydraulique est pourvu d'un régulateur 15a comprenant : un corps de cylindre 15a1 ; un tiroir cylindrique 15a2 qui coulisse à l'intérieur du corps de cylindre 15a1 ; une chambre pilote R11 dans laquelle une pression pilote est entrée sous forme de pression hydraulique pour amener le tiroir cylindrique 15a2 à se déplacer dans une direction axiale ; une chambre de sortie R12 de laquelle une pression de sortie est fournie sous forme de pression hydraulique en fonction de la pression pilote. Le dispositif de génération de pression hydraulique est pourvu : d'une partie d'acquisition de position de tiroir cylindrique 17c pour acquérir une position relative du tiroir cylindrique 15a2 par rapport au corps de cylindre 15a1 ; d'une partie de régulation de pression pilote 17d pour réguler la pression pilote sur la base de la position relative acquise par la partie d'acquisition de position de tiroir cylindrique 17c.
(JA) 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。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。
