Patent number: 9005352Abstract: Embodiments of the invention are directed towards a trap canister for adsorbing fuel vapor contained in breakthrough gas discharged from a main adsorbent canister. The main adsorbent canister is connected to a fuel tank has a case defining an adsorption chamber therein and an adsorbent filled in the adsorption chamber. The case has a first end open to the atmosphere and a second end for introducing breakthrough gas into the adsorption chamber. The adsorbent filled in the adsorption chamber adsorbs the fuel vapor contained in the breakthrough gas. The trap canister further has a bypass path for bypassing the adsorption chamber and a valve configured to block the bypass path and to allow for opening during refueling. This prevents the fuel vapor from flowing into the atmosphere during normal operation while also decreasing pressure loss during refueling.Type: GrantFiled: March 18, 2013Date of Patent: April 14, 2015Assignee: Aisan Kogyo Kabushiki KaishaInventors: Takashi Mani, Ryuji Kosugi

Patent number: 8474439Abstract: A fuel vapor processor has a fuel tank, a canister, a recovery pipe, a fuel pump, a negative pressure generator, a pressure regulator, a fuel intake pipe and a fuel intake regulator. The vapor pipe leads the fuel vapor generated in the fuel tank into the canister for trapping the fuel vapor. The recovery pipe connects the fuel tank and the canister for recovering the fuel vapor trapped in the canister into the fuel tank. The fuel intake pipe directly connects the fuel pump provided in the fuel tank with the negative pressure generator for leading fuel to the negative pressure generator. The negative pressure generator generates negative pressure depending on an amount of fuel supplied to the negative pressure generator from the fuel pump. The fuel vapor trapped in the canister is recovered to the fuel tank through the recovery pipe due to the negative pressure. The pressure regulator is connected with the fuel pump for returning excess fuel discharged from the fuel pump into the fuel tank.Type: GrantFiled: May 3, 2010Date of Patent: July 2, 2013Assignee: Aisan Kogyo Kabushiki KaishaInventors: Katsuhiko Makino, Junya Kimoto, Masanobu Shinagawa, Takashi Mani, Masakazu Hasegawa
