Patent number: 7249582Abstract: The present invention provides an intake apparatus which ensures the collision safety by having sufficient clearance margin to the engine hood by utilizing the space around the intake manifold which is not conventionally utilized, while achieving cost reduction by reduction in parts count and assembling time. The third member 14 covers the first member 10 in which the first room 24 is formed and the second member 12 in which the second room 38 is formed. The third room 54 which is formed in the third member 14 connects the first room 24 and the second room 38. With this structure, the second room 38 can be disposed adjacent to the first room 24 at almost the same height. Consequently, the height of the intake apparatus can be lowered, and the clearance between the intake apparatus and the engine hood can be enlarged. In addition, the intake air amount can be increased.Type: GrantFiled: October 5, 2004Date of Patent: July 31, 2007Assignee: Mikuni CorporationInventors: Hiroyuki Kawarai, Kazuyori Kito

Patent number: 7011064Abstract: An intake manifold is provided that comprises a plurality of intake ducts, a surge tank, a vacuum chamber, and a negative pressure check valve. The negative pressure check valve enables negative pressure induced in the surge tank to flow into the vacuum chamber. Each upstream end of the intake ducts protrudes into the inside of the surge tank. Further, a pressure inlet formed inside the surge tank, to lead the negative pressure induced inside the surge tank to the negative pressure check valve, is positioned on a side closer to an engine than the respective upstream ends of the intake ducts.Type: GrantFiled: June 14, 2004Date of Patent: March 14, 2006Assignees: Mikuni Corporation, Honda Giken Kogyo Kabushiki KaishaInventors: Kazuyori Kito, Tomonori Ikuma

Patent number: 6997157Abstract: The intake manifold assembly comprises three blocks each molded from a plastic material by injection molding, the three blocks consisting of a first block defining a half of the surge tank, a second block defining a half of the individual intake pipes and a third block defining a remaining half of the surge tank and a remaining half of the individual intake pipes. Thereby, the intake manifold assembly may be provided with various features for defining a pair of intake pipe sections arranged in a mutually parallel relationship while being made to be suitable for an injection molding process. Because the surge tank are defined by the first and third blocks while the individual intake pipes are defined by the second and third blocks, the intake manifold assembly essentially consisting of three blocks can internally define essential features required for a dual port intake device without requiring additional component members.Type: GrantFiled: June 14, 2004Date of Patent: February 14, 2006Assignee: Honda Motor Co., Ltd.Inventors: Tomonori Ikuma, Kazuyori Kito

Patent number: 6622682Abstract: In an intake manifold of an internal combustion chamber comprising a surge tank assembly and intake pipe assembly, a seal member is interposed between the end surface of the intake pipe assembly and the mating surface of the surge tank assembly so as to seal off the intake passage and mounting holes individually. Thus, the seal member, combined with the use of the blind threaded holes for the threaded bolts joining the two parts, ensures the sealing of both the intake passages and mounting holes at the interface between the end surface of the intake pipe and the mating surface of the surge tank assembly in a both reliable and simple manner. Preferably, the seal member comprises an O-ring made of elastomeric material, and at least one of the mating surface and end surface is provided with a groove for receiving the seal member.Type: GrantFiled: May 14, 2002Date of Patent: September 23, 2003Assignees: Honda Giken Kogyo Kabushiki Kaisha, Mikuni CorporationInventors: Tomonori Ikuma, Tetsu Wada, Kazuyoshi Sato, Kazuyori Kito, Yoshio Shibuya
