Publication number: 20170074263Abstract: A check valve provided makes it possible to operate a vane pump smoothly even at the start of the vane pump by maintaining an oil pressure in backpressure oil passages inside the vane pump while the vane pump is stopped. The check valve opens at the point in time when an oil pressure control device, to which a working fluid is supplied from the vane pump, has been filled with the working fluid and the oil pressure in discharge oil passages communicating with the oil pressure control device has risen and exceeded the oil pressure in the backpressure oil passages. Thus, the check valve is prevented from opening and closing repeatedly, so that the durability of the check valve is improved.Type: ApplicationFiled: September 12, 2016Publication date: March 16, 2017Applicants: TOYOTA JIDOSHA KABUSHIKI KAISHA, AISIN AW CO., LTD.Inventors: Yoshihiro MIZUNO, Shuji MORIYAMA, Yoshinobu SOGA, Takafumi INAGAKI, Hiromitsu NITANI, Mitsuhiro TAKEDA

Publication number: 20170074262Abstract: A vehicle hydraulic device is provided with an electric motor-driven oil pump and a shuttle valve, so that a vane pump operates smoothly, even at the start, with a backpressure applied from the electric motor-driven oil pump to the vanes. Even when the oil pressure of a working fluid discharged from the vane pump exceeds the backpressure inside vane housing grooves, the working fluid flows from a vane pump discharge oil passage to a backpressure oil passage, so that the vanes are not pushed into the housing grooves. Thus, it is possible to reduce the fluctuations in discharge amount of the vane pump due to fluctuations in oil pressure of the vane pump discharge oil passage during operation of the vane pump.Type: ApplicationFiled: September 8, 2016Publication date: March 16, 2017Applicants: TOYOTA JIDOSHA KABUSHIKI KAISHA, AISIN AW CO., LTD.Inventors: Yoshihiro MIZUNO, Yoshinobu SOGA, Shuji MORIYAMA, Takafumi INAGAKI, Hiromitsu NITANI, Mitsuhiro TAKEDA, Toshiaki HAYASHI, Yoshimitsu HYODO
