Patent number: 11781511Abstract: A fuel supply device includes a flange unit and a pump unit. The flange unit includes a flange main body for closing an opening formed in an upper wall of a fuel tank. The pump unit includes a joint member that is connected to the flange main body so that both components may be movable relative to each other in the vertical direction. The interval in the vertical direction between the flange main body and the joint member is restricted from going below a minimum vertical interval. The minimum interval occurs when a stand-off portion provided as part of the flange main body and a connecting plate portion provided as part of the joint member come into mutual contact with each other and abut each other in the vertical direction.Type: GrantFiled: January 13, 2017Date of Patent: October 10, 2023Assignees: AISAN KOGYO KABUSHIKI KAISHA, TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Kensuke Niwa, Koji Yoshida, Akira Iida, Shinya Higashi, Morihiro Takemura, Hiroyasu Kariya, Tatsuki Fukui, Takuhito Fujiwara, Takeaki Morizono, Takehiro Yamauchi, Ryosuke Hayashi

Patent number: 10907593Abstract: When a fuel tank is inclined at a negative slope and tilted to the right side, it may be tilted such that a position of a mesh member is relatively higher than a position of a vapor outlet of a vapor outlet passage. In this case, air may enter into a leak passage from an outlet port such that interfacial tension is generated in the mesh member. The interface between fuel and air is present at the mesh member, and the interfacial tension generated at the interface serves to prevent air from entering into a discharge pipe.Type: GrantFiled: January 23, 2017Date of Patent: February 2, 2021Assignee: Aisan Kogyo Kabushiki KaishaInventors: Shinya Higashi, Koji Yoshida, Kensuke Niwa, Hiroyasu Kariya, Morihiro Takemura, Tatsuki Fukui, Akira Iida, Takuhito Fujiwara, Takeaki Morizono, Takehiro Yamauchi

Patent number: 10850606Abstract: A flange main body as a cover member for a fuel tank includes a cover plate for closing an opening of the fuel tank, an accommodating tubular portion formed as part of the cover plate so as to extend through the plate in a plate thickness direction, and a rib formed at the cover plate. The accommodating tubular portion and the rib are formed to be non-contiguous.Type: GrantFiled: January 13, 2017Date of Patent: December 1, 2020Assignee: Aisan Kogyo Kabushiki KaishaInventors: Kensuke Niwa, Koji Yoshida, Akira Iida, Shinya Higashi, Morihiro Takemura, Hiroyasu Kariya, Tatsuki Fukui, Takuhito Fujiwara, Takeaki Morizono, Takehiro Yamauchi

Patent number: 10544762Abstract: A fuel supply device includes a flange unit configured to be attached to an upper wall of a fuel tank to close an opening of the fuel tank, a pump unit configured to be disposed within the fuel tank, and a coupling mechanism moveably coupling the pump unit to the flange unit in a vertically slidable manner. The coupling mechanism includes a fixed-side rail member having a rail portion extending vertically from the flange unit, and a movable-side rail member having a channel-groove shaped rail groove extending from the pump unit. The channel-groove shaped rail groove is slidably engaged with the rail portion of the fixed-side rail member. A recess having a semi-circular cross section is formed at a corner of the rail groove of the movable-side rail member.Type: GrantFiled: January 4, 2017Date of Patent: January 28, 2020Assignee: AISAN KOGYO KABUSHIKI KAISHAInventors: Tatsuki Fukui, Koji Yoshida, Akira Iida, Shinya Higashi, Morihiro Takemura, Hiroyasu Kariya, Takeaki Morizono, Takuhito Fujiwara, Kensuke Niwa, Takehiro Yamauchi
