Abstract

The invention relates to the technical field of valves, and particularly discloses an oil atomizer and a dynamic flow adjusting method thereof. The oil atomizer comprises a connecting body, a spring pin and a shell, wherein the spring pin is inserted into the connecting body and is in clearance fit with the connecting body; the shell covers the outer side of the connecting body and is provided with a plurality of through holes for a press-fitting machine to extend into; and the pressing machine is used for extruding the connecting body from outside to inside, so that the connecting body is fixedly connected with the spring pin. According to the oil atomizer and the dynamic flow adjusting method thereof, the position of the spring pin can be conveniently adjusted back in the dynamic flow adjusting process, the production difficulty can be reduced, and the production efficiency can be improved.

Description

technical field [0001] The invention relates to the technical field of valves, in particular to an injector and a dynamic flow adjustment method thereof. Background technique [0002] see figure 1 , generally, the fuel injector includes a valve body 1 with a valve hole 101, a needle valve 2 located above the valve hole 101, a compression spring 3 for driving the needle valve 2 to block the valve hole 101 downward, fixed to the compression spring 3 above the spring pin 4 and the coil 5 for driving the needle valve 2 to move downward. Under normal circumstances, the coil 5 is de-energized, driven by the compression spring 3, the needle valve 2 seals the valve hole 101 downwards, and the fuel cannot be ejected; when the coil 5 is energized, the needle valve 2 overcomes the elastic force of the compression spring 3 upward movement, the valve hole 101 is opened, and the fuel is sprayed out through the valve hole 101. [0003] It can be understood that the spring pin 4 is used ...
