Further, when the coil is powered off, the spring pushes the hollow valve core and the hollow piston to the left, and the oil hole is communicated with the buffer cavity, the main spray hole and the auxiliary spray hole;
when the coil is electrified, the hollow valve core pushes the hollow piston to the right position, the end face of the hollow piston is in contact with the side wall of the buffer cavity, the auxiliary spray hole is blocked, and the oil hole is only communicated with the main spray hole.
Furthermore, the rear cover is of a circular ring structure, a circular ring protrusion is arranged on the right side of the rear cover, and the circular ring protrusion of the rear cover is inserted into the left end hole of the body.
Compared with the prior art, the invention has the following advantages:
(1) the electromagnetic valve integrated in the nozzle of the combustion chamber has the function of changing the area of the spray hole according to the fuel flow demand, and when the combustion chamber needs smaller oil supply amount, the nozzle only supplies oil through the main spray hole; when the combustion chamber needs larger oil supply amount, the electromagnetic valve in the nozzle acts, the auxiliary spray hole is opened, and the main spray hole and the auxiliary spray hole supply oil simultaneously.
