[0044] The technical solution of this utility model will be described in detail below with reference to the accompanying drawings and specific embodiments to further understand the purpose, solution and effect of this utility model, but it is not intended to limit the scope of protection of the appended claims of this utility model.

[0045] The specification and subsequent claims use certain terms to refer to specific components or parts. Those skilled in the art will understand that users or manufacturers may use different names or terms to refer to the same component or part. This specification and subsequent claims do not distinguish components or parts by differences in name, but rather by differences in function. The terms "comprising" and "including" used throughout the specification and subsequent claims are open-ended and should be interpreted as "including but not limited to". Furthermore, the term "connection" here includes any direct and indirect electrical connection means. Indirect electrical connection means include connections made through other means.

[0046] It should be noted that in the description of this utility model, the terms "lateral", "longitudinal", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", as well as "about", "approximately", "substantially", "left and right", etc., indicating the orientation or positional relationship or parameters, are all based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, a specific size, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0047] See Figure 1-5 This utility model provides a fuel supply system with complete isolation between the oil storage chamber and the oil outlet, including: an oil storage chamber 1; and a body 2, wherein the oil storage chamber 1 is locked to the body 1 by an oil storage chamber fastening bolt 3; and an oil outlet channel 12 is provided on the body 2; wherein the oil storage chamber 1 includes an oil storage cavity 11, and the oil storage cavity 11 and the oil outlet channel 12 are completely isolated.

[0048] In this embodiment, the oil storage chamber 11 includes a main oil storage chamber 111 and a secondary oil storage chamber 112. The main oil storage chamber 111 and the secondary oil storage chamber 112 are connected and installed through the oil passage hole 113 between the main and secondary oil storage chambers.

[0049] A foam tube sealing ring 4 is provided between the oil storage chamber 1 and the main body 2 to block the main oil storage cavity 111 of the oil storage chamber 1 and the oil outlet channel 12.

[0050] Among them, an oil storage chamber fastening bolt sealing gasket 5 is provided between the oil storage chamber fastening bolt 3 and the oil storage chamber 1 to block the secondary oil storage chamber 112 of the oil storage chamber 1 and the oil outlet channel 12.

[0051] The fuel supply system described in this embodiment also includes a solenoid valve 6, which is locked onto the fuel reservoir 1 by a solenoid valve fastening screw 7. The fuel reservoir 1 is also provided with a solenoid valve fastening screw mounting hole 114 for mounting the solenoid valve fastening screw 7.

[0052] In this embodiment, a solenoid valve sealing ring 8 is provided between the solenoid valve 6 and the oil storage chamber 1 to seal and prevent oil leakage to the outside; the solenoid valve 6 is provided with a retractable and extendable solenoid valve needle 61; the oil storage chamber fastening bolt 3 includes a bolt inlet hole 31, a sealing valve line 32 and a bolt outlet hole 33; the solenoid valve needle 61 can extend and press against the sealing valve line 32 of the oil storage chamber fastening bolt 3.

[0053] In this embodiment, the fuel supply system that completely isolates the oil reservoir and the oil outlet provides a complete separation of fuel supply. When the engine is running, the solenoid valve needle 61 of the solenoid valve 6 retracts, and the fuel in the oil reservoir 1 reaches the oil outlet 12 through the inner hole of the oil reservoir fastening bolt 3, supplying fuel to the engine according to the operating conditions. When the engine stops, the solenoid valve needle 61 of the solenoid valve 6 extends and presses against the sealing valve line 32 of the oil reservoir fastening bolt 3, blocking the fuel from passing through the oil reservoir fastening bolt 3. With the combined effect of the oil reservoir fastening bolt sealing gasket 5 and the foam tube sealing ring 4, the oil reservoir 1 and the oil outlet 12 are completely isolated.

[0054] The fuel supply system provided by this utility model, which completely isolates the oil reservoir and the oil outlet, uses an electromagnetic valve to isolate the oil reservoir and the oil outlet, thereby improving safety. When the engine is turned off or malfunctions, the electromagnetic valve can quickly cut off the connection between the oil reservoir and the oil outlet, preventing fuel from continuing to flow into the combustion chamber or other parts, thereby reducing the risk of fire or explosion.

[0055] The fuel supply system provided by this utility model isolates the threaded section, achieving complete separation between the oil reservoir and the oil outlet, avoiding the risk of oil leakage, and improving the safety and reliability of the fuel supply system.

[0056] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
