Patent number: 11459989Abstract: The present disclosure relates to a clip for an injector, in particular, the clip for the injector including a base portion and an elastic piece of the clip that elastically support the upper surface of a connector housing and the lower surface of an injector cup, thus attenuating fuel injection load. In addition, an engaging piece of the clip is inserted into an engaging portion of the injector cup, thus preventing the rotation of the injector.Type: GrantFiled: June 21, 2018Date of Patent: October 4, 2022Assignee: Hyundai Kefico CorporationInventors: Seung Hyuk Oh, Young Il Kang, Kwang Won Koo, Yeon Jee Oh

Patent number: 11085408Abstract: The present disclosure relates to a pulsation dampening structure for a vehicle. The pulsation dampening structure includes a fuel rail, a rail plug disposed at an end portion of the fuel rail, and a pulsation dampening part disposed on the rail plug to dampen pulsation generated when fuel enters. A turbulent flow is caused by reflecting fuel which was entered, and a vortex is generated in the fuel, thereby dampening pulsation.Type: GrantFiled: December 27, 2018Date of Patent: August 10, 2021Assignee: HYUNDAI KEFICO CORPORATIONInventors: Seung Hyuk Oh, Kwang Won Koo, Yeon Jee Oh

Patent number: 10718303Abstract: Disclosed herein is an injector fixing structure of a fuel rail. The injector fixing structure for a fuel rail module is configured such that an injector cup that includes a slot formed at a side thereof and an injector that includes an anti-rotation pin inserted into the slot are coupled to each other by a clip. The injector fixing structure also includes a lock formed integrally with the anti-rotation pin, and a fixing member coupled to the slot and allowing the lock to be secured when the anti-rotation pin is inserted into the slot such that the anti-rotation pin is prevented from being separated from the slot. The present invention may prevent separation of the injector from the fuel rail during transportation of the fuel rail module, thereby improving assemblability of the fuel rail module in engine assembly and increasing process efficiency.Type: GrantFiled: June 26, 2018Date of Patent: July 21, 2020Assignee: HYUNDAI KEFICO CORPORATIONInventors: Seung-Hyuk Oh, Young-II Kang, Kwang-Won Koo, Yeon-Jee Oh

Patent number: 10612507Abstract: Disclosed herein is a mounting structure of a fuel rail, including a mounting boss part having a through-hole formed in a longitudinal direction and a first mating surface formed at an outer surface, an injector cup part provided separately from the mounting boss part and having a second mating surface formed at an outer surface and a flow path hole formed at one side of the second mating surface to be connected to the main pipe for transferring fuel to an injector, and a bridge part connecting the mounting boss part and the injector cup part and having a third mating surface. The mounting structure of the fuel rail can effectively distribute stress concentration by increasing contact area with the main pipe, thereby improving fatigue strength.Type: GrantFiled: April 13, 2018Date of Patent: April 7, 2020Assignee: HYUNDAI KEFICO CORPORATIONInventors: Seung Hyuk Oh, Young Il Kang, Kwang Won Koo, Myeong Hun Kweon, Yeon Jee Oh

Patent number: 10094351Abstract: An injector clip includes a lower plate formed to support a fuel injection portion of an injector, a base plate is formed to engage with and support a connection portion of the injector and an engagement support portion elastically supports the lower plate and the base plate to return the fuel injection portion to an original position after being displaced. A spring arm is formed by extending from the base plate to support a fuel inlet portion of the injector. Accordingly the load resulting from fuel injection of a fuel injector is attenuated and p a fuel injection device is prevented from rotating.Type: GrantFiled: June 13, 2017Date of Patent: October 9, 2018Assignee: HYUNDAI KEFICO CORPORATIONInventors: Seung Hyuk Oh, Young Il Kang, Kwang Won Koo, Myeong Hun Kweon, Yeon Jee Oh
