Description

Technical Field

[0001] The utility model relates to the technical field of solenoid valves, in particular to a carburetor solenoid valve for automobiles. Background Technique

[0002] A carburetor solenoid valve usually consists of a main body part and an electromagnet. The electromagnet is controlled by a power supply to switch the valve inside to control the fuel. When the electromagnet is energized, it generates a magnetic field to attract the valve to close and block the entry of fuel. When the electromagnet stops being energized, the magnetic field disappears, the valve opens, and the fuel can smoothly enter the carburetor.

[0003] After retrieval, in the application with the patent publication number CN203549072U, a carburetor solenoid valve for automobiles is disclosed, which includes a housing, a cover, and a signal input wire. The housing and the cover are threadedly connected. A skeleton and a driving coil are arranged inside the housing. A moving iron core and a fixed iron core are arranged inside the skeleton. A needle rod is fixed on the moving iron core. The needle rod penetrates through the fixed iron core and the housing. A return spring is arranged between the moving iron core and the fixed iron core, and a buffer pad is arranged between the moving iron core and the cover, so that the moving iron core can reset quickly and completely, and the response speed of the solenoid valve is faster.

[0004] However, due to the setting of the solenoid valve housing, it is not convenient to stably install the solenoid valve on the carburetor and connect it to the carburetor. At the same time, since the solenoid valve is directly installed on the outer shell of the carburetor, the sealing performance between the solenoid valve needle rod and the carburetor connection is poor, affecting its use effect.

[0005] Therefore, we propose a carburetor solenoid valve for automobiles. Content of the Utility Model
