  • Patent number: 10562758
    Abstract: Disclosed is a valve apparatus of a urea tank for a vehicle, the valve apparatus configured such that a urea solution injection pipe is flexibly bent and has a float so that a urea injection valve provided at the urea solution injection pipe is prevented from being immersed in the urea solution in the urea tank. Thus, the urea solution can be prevented from being damaged upon freezing in a winter season. Further, when a urea solution is injected, the urea solution injection pipe is straightened by flow pressure of the urea solution such that the float is forced to be immersed in the urea solution in the urea tank, and accordingly the urea solution injection valve is immersed therein. Thus, the urea solution can be efficiently injected into the urea tank.

  • Patent number: 9644518
    Abstract: 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.
