Title
(EN) VALVE OPENING/CLOSING TIMING CONTROLLER
(FR) CONTROLEUR DE TEMPORISATION D’OUVERTURE/FERMETURE DE SOUPAPE

Abstract
(EN)
A valve opening/closing timing controller capable of suppressing the entry of foreign matter into the sliding parts of a lock member by suppressing the deposition of foreign matter in an engagement recessed part and having a lock mechanism capable of reducing the sliding resistance of the lock member. The lock mechanism (5) comprises a sliding groove (52) formed in an outer rotor (2), the lock member (53) slidable along the sliding groove (52), and the engagement recessed part (51) formed in an inner rotor (3), formed so that the lock member (53) can be engaged therewith in the locked state of a relative rotation phase, and having an inflow port (58) allowing a working fluid to flow therein. A working fluid flow passage (57) formed along the sliding direction of the lock member (53) and communicating with the engagement recessed part (51) is formed in at least one of the sliding groove (52) and the lock member (53).

La présente invention concerne un contrôleur de temporisation d’ouverture/fermeture de soupape capable de supprimer l’entrée d’un corps étranger dans les parties coulissantes d’un élément de verrouillage, en supprimant le dépôt de corps étrangers dans une partie encastrée de mise en prise et en ayant un mécanisme de verrouillage capable de réduire la résistance au coulissement de l’élément de verrouillage. Le mécanisme de verrouillage (5) comprend une rainure de glissement (52) formée dans un rotor extérieur (2), l’élément de verrouillage (53) pouvant coulisser le long de la rainure de glissement (52) et la partie encastrée de mise en prise (51) formée dans un rotor intérieur (3), formée afin que l’élément de verrouillage (53) puisse être mis en prise avec celui-ci dans l’état verrouillé d’une phase de rotation relative, ledit mécanisme ayant un orifice d’admission (58) permettant à un fluide thermodynamique de s’écouler à l’intérieur. Un passage d’écoulement de fluide thermodynamique (57) formé le long de la direction coulissante de l’élément de verrouillage (53) et communiquant avec la partie encastrée de mise en prise (51) est formé dans au moins un élément parmi la rainure de glissement (52) et l’élément de verrouillage (53).
