Description

Technical Field

[0001] This utility model relates to the field of oil pipeline technology, and in particular to an oil rail. Background Technology

[0002] Currently, the fuel rail is a crucial component in automobiles used to connect the fuel pump and fuel injectors. During vehicle assembly, the fuel injectors are first connected to the connectors on the fuel rail, then the connectors are installed on the vehicle, and finally the fuel lines are connected to one end of the connectors. While this method is feasible, it involves numerous installation steps and is highly susceptible to errors such as incorrect or improper installation. Furthermore, due to the numerous connection points, leaks can easily occur during use due to poor sealing or loose connections.

[0003] In summary, this application proposes an oil rail to solve the aforementioned problems. Utility Model Content

[0006] The three-way mounting pipe includes an oil inlet and a pair of oil outlets with a vertical oil inlet. The oil outlets are connected to connector A and connector B respectively through connecting oil pipes. The oil inlet and oil outlet are integrally formed.

[0007] Further description: Both connector A and connector B include an integrally formed plug portion and a fixing seat. The plug portion is located on the outer wall of the fixing seat. One end of the plug portion is provided with an oil inlet port that communicates with the plug portion and is used to connect to the connecting oil pipe. Bolt holes are provided on the fixing seat.

[0008] In this invention, the connecting oil pipe includes an inner oil pipe and an outer oil pipe, with the oil outlet and oil inlet respectively inserted into the two ends of the inner oil pipe; the two ends of the outer oil pipe are respectively sleeved on the outer walls of the oil outlet and oil inlet.

[0009] To ensure sealing performance, sealing rings are provided on both the oil outlet and the oil inlet; this improves the sealing between the tee installation pipe and connectors A and B and the connecting oil pipe.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: the oil rail, through the cooperation of the three-way installation pipe, connecting oil pipe, connector A and connector B, can perform dual-head oil injection. Compared with the installation of traditional oil rails, during installation, it can be quickly fixed to the car with bolts; it reduces the steps of component assembly, docking and tightening, which can significantly reduce installation time and labor costs. This device is mostly installed in one piece, avoiding the connection between multiple components, reducing the risk of oil leakage caused by improper connection parts, and the integrity of the oil rail makes it more stable when subjected to pressure and vibration.

[0016] In the description of this utility model, it should be understood that the directional descriptions, such as up, down, front, back, left, right, etc., indicate the directional or positional relationship based on the directional 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, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0017] Example 1: As Figure 1 , 2 As described in sections 3 and 4, an oil rail includes a tee mounting pipe 1, a connector A2, and a connector B3. The tee mounting pipe 1 is connected to the connector A2 and the connector B3 respectively via connecting oil pipes 4. The tee mounting pipe 1, the connector A2, and the connector B3 are arranged in a U-shape.

[0018] The three-way installation pipe 1 includes an oil inlet 5 and a pair of oil outlets 6 with the vertical oil inlet 5. The oil outlets 6 are connected to connector A2 and connector B3 respectively through connecting oil pipe 4. The oil inlet 5 and the oil outlets 6 are integrally formed.

[0019] In this utility model, both connector A2 and connector B3 include an integrally formed plug portion 8 and a fixing base 9. The plug portion 8 is located on the outer wall of the fixing base 9. An oil inlet port 10 is provided at one end of the plug portion 8, which communicates with the plug portion 8 and is used to connect to the connecting oil pipe 4. A bolt hole 11 is provided on the fixing base 9.

[0020] During installation, the fuel injector is directly inserted into the connector 9, and then the invention is installed on the vehicle using bolts and bolt holes 11. Finally, the fuel pump is connected to the fuel inlet 5 via a fuel line.
