Patent number: 9644518Abstract: A urea filler neck for preventing a urea overflow includes a filler housing forming a urea path in which urea flows to a urea tank. An injection gun guide is provided in the filler housing. An end of an injection gun is fixed by the injection gun guide to limit an insertion position of the injection gun inserted into an inlet of the filler housing. An injection gun guide flooding phenomenon is generated, in which urea flowing backward from the urea tank rises to block an air flow in the filler housing being generated in the injection gun guide. A filler housing pressure increasing phenomenon is generated, in which a pressure in the filler housing is increased due to blocking of the air flow by the injection gun guide flooding phenomenon being generated in the injection gun guide.Type: GrantFiled: December 3, 2014Date of Patent: May 9, 2017Assignees: Hyundai Motor Company, Korea Fuel-Tech CorporationInventors: Chang-Ho Ham, Pil-Seon Choi, Dong-Myoung Ryoo, Young-Jae Lim, Myung-Keun Chae

Patent number: 9528478Abstract: A fuel feeding system for a vehicle may include a fuel tank and a subsidiary jet pump. The fuel tank is divided into a first portion in which a reservoir is installed and a second portion in which the subsidiary jet pump is installed. The subsidiary jet pump pumps out fuel pressurized by a fuel pump and causes the fuel in the second portion of the fuel tank to enter the reservoir using a pressure difference generated during pumping of the fuel. The subsidiary jet pump includes a nozzle unit and a diffuser unit. The diffuser unit surrounds an injection portion of the nozzle unit with a suction channel disposed therebetween. The suction channel has a suction hole and a discharge hole and is structured to cause fuel suctioned through the suction hole and fuel discharged through the discharge hole to flow in the same direction.Type: GrantFiled: November 13, 2014Date of Patent: December 27, 2016Assignee: Hyundai Motor CompanyInventors: Seung Hwan Park, Pil Seon Choi, Bu Yeol Ryu, Seung Yup Oh, Sung Hwan Chi
