PURPOSE: An injection nozzle having a reverse flow prevention function is provided to offer a discharge vent formed by the joint of two extended inclined planes for efficiently preventing the reverse flow or inflow of foreign substances. CONSTITUTION: An injection nozzle having a reverse flow prevention function comprises a base(11), a discharge body(12), a first inclined plane(13a), a second inclined plane(13b), and a discharge vent(14). Repair liquid flows within the base. The discharge body is extended from the base. The first inclined plane is extended to one part of the boundary of the discharge body. The second inclined plane is extended to other part of the boundary of the discharge body. The discharge vent is formed where the first inclined plane meets the second inclined plane. The opening size of the discharge vent is adjusted by the deformation of the first and the second inclined planes which are asymmetric. |
