Abstract
Official abstract text for this publication.
A leveling nipple for a tank may include a first pipe that includes a curved portion discharging air inside the tank to an outlet pipe when a fluid is supplied to the tank; and a second pipe that discharges air inside the tank to the outlet pipe when the fluid is supplied to the tank and is connected to the curved portion of the first pipe, wherein the second pipe includes a diversion portion that guides the fluid flowing into the second pipe to the first pipe.
First claim
Opening claim text (preview).
What is claimed is: 1. A leveling nipple for a tank, the leveling nipple comprising: a first pipe that includes a curved portion discharging air inside the tank to an outlet pipe when a fluid is supplied to the tank; and a second pipe that discharges air inside the tank to the outlet pipe when the fluid is supplied to the tank and is directly connected to the curved portion of the first pipe, wherein the second pipe includes a diversion portion that guides the fluid flowing into the second pipe to the first pipe, wherein the first pipe further includes a nozzle connected to an end portion of the curved portion, and wherein the nozzle includes a contraction nozzle. 2. The leveling nipple of claim 1 , wherein an opening reducing pressure inside the tank is formed at a lower portion of the second pipe. 3. The leveling nipple of claim 1 , wherein a length of the first pipe is greater than a length of the second pipe. 4. The leveling nipple of claim 1 , wherein the tank includes a urea tank of a vehicle. 5. The leveling nipple of claim 1 , wherein the first pipe and the second pipe are formed adjacent to each other. 6.
