ELECTRIC-CONTROLLED FUEL SECTION Russian patent published in 2024 - IPC F02M59/02 F02M59/44 F02M59/46 

FIELD: internal combustion engines.

SUBSTANCE: invention can be used in fuel supply systems of internal combustion engines. According to the invention, electrically controlled valve 2 is located in the upper part of housing 1, with fitting 3 installed perpendicular to it. At the end side of housing 1 there is electromagnet 7, which is a non-separable assembly unit consisting of housing 18, coil 21, frame 19 and core 20, and electromagnet coil 21 is wound transversely on U-shaped core 20. Stabilizer 4 is installed in the cavity of fitting 3, pressed by spring 5 and fixed by stop 6, and the seal of stop 6 and housing 1 is achieved due to the difference in the angles of the cones of the contact surfaces. At the end of stabilizer 4 there is a hole, the diameter of which varies from 0.35 to 2.0 mm depending on the requirements. In the lower part of housing 1 there are cavities for drainage fuel 15, fuel supply 13 and fuel outlet 14, separated from each other by sealing rings 16, as well as locking ring 12 securing the parts. In the lower part of the body there are two through holes 17 for removing the locking ring 12.

EFFECT: invention makes it possible to simplify the design and reduce the labor intensity of manufacturing, as well as increase the operating efficiency of the electrically controlled fuel section of the high-pressure fuel pump.
