Title (EN) HYDRAULIC PRESSURE SUPPKY DEVICE FOR AUTOMATIC TRANSMISSION
(FR) DISPOSITIF D'ALIMENTATION EN PRESSION HYDRAULIQUE POUR BOÎTE DE VITESSES AUTOMATIQUE
(JA) 自動変速機の油圧供給装置
Abstract:
(EN) This hydraulic pressure supply device (10) for an automatic transmission comprises: a variable displacement oil pump (20); a regulator valve (40) for regulating the discharge pressure of the oil pump to a predetermined pressure; and a feedback oil passage (57) for conducting hydraulic pressure outputted from the regulator valve (output port C1) to the control chamber (36) of the oil pump. The oil pump is configured such that an increase in hydraulic pressure in the control chamber causes a decrease in the discharge pressure and such that a decrease in hydraulic pressure in the control chamber causes an increase in the discharge pressure. The hydraulic pressure supply device (10) further comprises an oil supply limiting device (80) provided in the feedback oil passage and limiting oil supply to the control chamber more than oil discharge from the control chamber.
(FR) Le dispositif d'alimentation en pression hydraulique (10) pour une boîte de vitesses automatique selon l'invention comprend : une pompe à huile à cylindrée variable (20) ; une soupape de régulation (40) permettant de réguler la pression de refoulement de la pompe à huile à une pression prédéterminée ; et un passage d'huile de retour (57) permettant de conduire une pression hydraulique délivrée à partir de la soupape de régulation (orifice de sortie (C1)) vers la chambre de commande (36) de la pompe à huile. La pompe à huile est configurée de sorte qu'une augmentation de la pression hydraulique dans la chambre de commande provoque une diminution de la pression de refoulement et de sorte qu'une diminution de la pression hydraulique dans la chambre de commande provoque une augmentation de la pression de refoulement. Le dispositif d'alimentation en pression hydraulique (10) comprend en outre un dispositif de limitation d'alimentation en huile (80) disposé dans le passage d'huile de retour et limitant l'alimentation en huile de la chambre de commande davantage que le refoulement d'huile à partir de la chambre de commande.
(JA) 自動変速機の油圧供給装置(10)が、可変容量型のオイルポンプ(20)と、該オイルポンプの吐出圧を所定圧に調整するレギュレータバルブ(40)と、該レギュレータバルブ(出力ポートC1)から出力された油圧を前記オイルポンプの制御室(36)に導くフィードバック油路(57)とを備え、前記オイルポンプは、前記制御室の油圧が上昇することで前記吐出圧が低下する一方、前記制御室の油圧が低下することで前記吐出圧が上昇するように構成され、前記フィードバック油路に設けられ、前記制御室からの排油に比べて該制御室への給油を制限する給油制限装置(80)を更に備えている。
