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: 11168655Abstract: A fuel filter device includes a bag-shaped filter member filtering fuel that is drawn into a fuel pump, an inner frame member retaining the filter member in an expanded state, and a mounting member connected to the inner frame member and serving to communicate an internal space of the filter member with an outside. A valve chamber is defined by the inner frame member and the mounting member, and a check valve serving to prevent backflow of fuel is disposed in the valve chamber. The check valve includes a flat-plate shaped valve body having elasticity. The check valve opens against its weight when the fuel pump is operated, and the check valve closes due to its weight when the operation of the fuel pump is stopped.Type: GrantFiled: September 10, 2015Date of Patent: November 9, 2021Assignee: AISAN KOGYO KABUSHIKI KAISHAInventors: Kensuke Niwa, Koji Yoshida, Tatsuki Fukui, Hiroyasu Kariya

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
