Abstract

The invention relates to a spiral nozzle which comprises a valve body, a valve seat, a valve core and an oil circuit, wherein an oil inlet is formed in one end of the valve body, the other end of thevalve body is connected with the valve seat, an atomizing hole is formed in the valve seat, the valve core is arranged in the valve body, one end of the valve core is connected with the valve seat ina sealed mode, the oil circuit is arranged between the valve core and the valve body, the two ends of the oil circuit respectively communicate with the oil inlet and the atomizing hole, the valve seatis provided with a swirling structure which plays a swirling effect on media, and the oil circuit communicates with the atomizing hole through the swirling structure. According to the spiral nozzle,the spiral groove is innovatively additionally arranged on the valve seat, so that the media start to rotate under the interaction of shearing pressure in the vertical direction and the spiral direction, and enter the atomizing hole of the valve seat at a higher speed, and the atomization performance of the nozzle is greatly improved.

Description

technical field

[0001] The invention belongs to the technical field of automobile engines, and in particular relates to a spiral nozzle. Background technique

[0002] The fuel injector is one of the key components of the engine, and its performance will seriously affect the performance of the engine. In existing automobile engines, people have adopted various types of nozzles to improve spray quality, such as high and low pressure direct injection nozzles, swirl nozzles, etc.

[0003] Publication number is the utility model patent of CN2606192, specifically discloses a kind of electric fuel injection fuel injector of automobile, comprises valve body, nozzle orifice plate, ball head, shell, and the nozzle hole on the nozzle orifice plate is 2-3. The patent has the advantages of simple structure, sufficient combustion, and little environmental pollution. However, due to the solid injection of this porous high and low pressure direct injection nozzle, when the injection press...
