Title
(EN) OIL INTAKE DEVICE FOR VEHICLE
(FR) DISPOSITIF D'ADMISSION D'HUILE POUR VÉHICULE
(JA) 車両のオイル吸入装置
Abstract
(EN)
Provided is an oil intake device provided with a primary intake opening (51) which is disposed on an inflow edge (41a) of a narrow tube (41) and through which oil in an oil retention unit (20) is taken in, and a tertiary intake opening (53) which is formed in a gap between a first tapered surface (32) and a second tapered surface (42) by the displacement of the narrow tube (41) relative to a wide tube (31). The oil intake device is configured so that, if the intake pressure of an oil pump (10) is less than a prescribed pressure, only oil from the primary intake opening (51) is taken in and, if the intake pressure of the oil pump (10) is at least the prescribed pressure, the tertiary intake opening (53) is formed in the gap between the first tapered surface (32) and the second tapered surface (42) by the displacement of the narrow tube (41) relative to the wide tube (31) and air from the tertiary intake opening (53) is taken in. The drive torque of a mechanical oil pump driven by rotation transmitted from a drive source of a vehicle can be reduced and loss imparted to the drive source can be effectively reduced.
(FR)
L'invention porte sur un dispositif d'admission d'huile, qui comporte une ouverture d'admission primaire (51) qui est disposée sur un bord d'entrée (41a) d'un tube étroit (41), et à travers laquelle est admise l'huile dans une unité de retenue d'huile (20), et une ouverture d'admission tertiaire (53) qui est formée dans un intervalle entre une première surface effilée (32) et une seconde surface effilée (42) par le déplacement du tube étroit (41) par rapport à un tube large (31). Le dispositif d'admission d'huile est conçu de telle sorte que, si la pression d'admission d'une pompe à huile (10) est inférieure à une pression prescrite, seule l'huile provenant de l'ouverture d'admission primaire (51) est introduite et, si la pression d'admission de la pompe à huile (10) est au moins égale à la pression prescrite, l'ouverture d'admission tertiaire (53) est formée dans l'intervalle entre la première surface effilée (32) et la seconde surface effilée (42) par le déplacement du tube étroit (41) par rapport au tube large (31), et l'air provenant de l'ouverture d'admission tertiaire (53) est admis. Le couple d'entraînement d'une pompe à huile mécanique, entraînée par la rotation transmise par une source d'entraînement du véhicule, peut être réduit et la perte appliquée à la source d'entraînement peut être effectivement réduite.

細管(41)の流入端(41a)に設けられてオイル貯留部(20)内のオイルを吸入する1次吸入口(51)と、細管(41)が太管(31)に対して相対移動することで第1テーパ面(32)と第2テーパ面(42)との隙間に形成される3次吸入口(53)と、を備え、オイルポンプ(10)の吸入圧が所定圧未満では、1次吸入口(51)からオイルのみを吸入し、オイルポンプ(10)の吸入圧が所定圧以上になると、細管(41)が太管(31)に対して相対移動することで、第1テーパ面(32)と第2テーパ面(42)との隙間に3次吸入口(53)が形成されて3次吸入口(53)から空気が吸入されるように構成したオイル吸入装置である。車両の駆動源から伝達された回転で駆動する機械式のオイルポンプの駆動トルクを低減することができ、駆動源に与える損失を効果的に低減できる。
