要約
(EN)
Provided is a valve opening/closing period control device at which an oil pathway has been accurately formed at a low cost. The valve opening/closing period control device is provided with: an advance chamber and delay chamber formed by partitioning, by means of a partition section provided to the outer peripheral side of a driven-side rotating body, a fluid pressure chamber formed between a drive-side rotating body and the driven-side rotating body, which is disposed in a manner able to rotate relative to the inner peripheral surface of the drive-side rotating body; an advance duct that interconnects with the advance chamber; and a delay duct interconnected to the delay chamber. The driven-side rotating body is formed having: a tubular first member to which the partition section is provided; and a tubular second member provided on the same rotational axis center as the first member and having a portion overlapping the inside in at least the radial direction of the first member among the radial direction and axial direction of the first member. The advance duct and delay duct are formed penetrating the boundary section of the first member and second member after assembling the first member and second member.

L'invention concerne un dispositif de commande de période d'ouverture/de fermeture de soupapes dans lequel un trajet d'huile a été formé avec précision et à bas coût. Le dispositif de commande de période d'ouverture/de fermeture de soupapes comprend : une chambre d'avance et une chambre de retard formées en divisant, au moyen d'une section de séparation agencée côté périphérique externe d'un corps rotatif côté entraîné, une chambre de pression de fluide formée entre un corps rotatif côté entraînement et le corps rotatif côté entraîné, qui est disposé de manière à pouvoir tourner par rapport à la surface périphérique interne du corps rotatif côté entraîné ; un conduit d'avance qui est relié à la chambre d'avance ; et un conduit de retard relié à la chambre de retard. Le corps rotatif côté entraîné est formé en ayant : un premier élément tubulaire auquel est fixée la partie de séparation ; et un second élément tubulaire agencé sur le même centre d'axe de rotation que celui du premier élément tubulaire et comportant une partie qui recouvre l'intérieur au moins dans la direction radiale du premier élément entre la direction radiale et la direction axiale du premier élément. Le conduit d'avance et le conduit de retard sont formés de sorte à pénétrer dans la section de limite du premier élément et du second élément après l'assemblage du premier élément et du second élément.
