[0002] Actuator solenoid valves are the core control components of various actuators. They are essentially "electromagnetically driven precision switches". By receiving electrical signals from the ECU (electronic control unit) or controller, they convert electrical energy into mechanical action, thereby controlling the actuator to complete specific tasks. They are widely used in automobiles, industrial equipment, home appliances and other fields, and are also a key bridge connecting "instructions" and "actions" in automotive electronic control systems.

[0017] Example 1 In this embodiment, an actuator solenoid valve with a built-in electromagnetic force adjustment device is proposed, which means that the oil output can be precisely controlled through electromagnetic adjustment, resulting in excellent control performance.
[0018] like Figures 1-3As shown, in one embodiment of this utility model, the actuator solenoid valve with a built-in electromagnetic force adjustment device includes a base 1, a base sealing ring 2, a solenoid valve module 3, a one-way valve 4, an adjusting sleeve 5, an armature 6, an armature support plug 7, an armature adjusting pad sleeve 8, an adjusting shim 9, an armature support column 10, a solenoid valve spring 11, a solenoid valve plug sealing ring 12, and a solenoid valve plug 13. The base 1 is provided with an oil inlet 14, a first mounting cavity, and an oil outlet 15. The first mounting cavity is used to install various components, the oil inlet 14 is used for oil inlet, and the oil outlet 15 is used for oil outlet. The solenoid valve module 3 is provided with a second mounting cavity and is detachable from the base 1. The connection is as follows: the base sealing ring 2 is set between the base 1 and the solenoid valve module 3, and the second mounting cavity is connected to the first mounting cavity. Specifically, there are two sets of corresponding through holes between the solenoid valve module 3 and the base 1. The present invention also includes bolts. The base 1 is detachably connected to the solenoid valve module 3 by bolts, that is, the bolts are set in the two sets of corresponding through holes. The one-way valve 4 is set in the oil outlet 15. The one-way valve 4 can prevent oil backflow. When the present invention is working, excessive pressure will produce excessive oil. At this time, this oil can flow out through the one-way valve 4. The oil outlet 15 of the present invention is specifically connected to the external oil tank so that it flows into the oil tank. The adjusting sleeve 5 of this utility model is disposed on one side of the first mounting cavity, the armature 6 is disposed on the other side of the first mounting cavity, the armature support plug 7 is disposed in the first mounting cavity and fits against the armature 6, the armature adjusting pad sleeve 8 is disposed in the first mounting cavity and fits over the upper part of the armature support plug 7, the adjusting shim 9 is disposed on the upper side between the armature adjusting pad sleeve 8 and the armature support plug 7 and fits against the adjusting sleeve 5, the oil inlet 14 and the oil outlet 15 are both connected to the first mounting cavity, and the armature support column 10 is disposed in the second mounting cavity with one end extending out. The solenoid valve module 3 passes through the armature 6 and is connected to the armature support plug 7. The solenoid valve spring 11 is located in the second mounting cavity and is sleeved on the end of the armature support column 10 away from the base 1. The solenoid valve plug 13 is located in the second mounting cavity on the side away from the base 1, and the side of the solenoid valve plug 13 close to the base 1 extends into the solenoid valve spring 11. The sealing ring 12 of the solenoid valve plug 13 is sleeved on the outer wall of the solenoid valve plug 13 and is located in the second mounting cavity. The solenoid valve plug 13 of this utility model is installed (threaded connection) on the solenoid valve module 3, which can prevent oil leakage. Please continue to refer to Figure 3The solenoid valve module 3 of this utility model includes a solenoid valve body 31 and a solenoid valve mounting component 32. The solenoid valve mounting component 32 is disposed inside the solenoid valve body 31, and a second mounting cavity is located inside the solenoid valve mounting component 32. Silicon steel 33 and enameled wire 34 are sequentially arranged on the outer side of the solenoid valve mounting component 32. Both the silicon steel 33 and the enameled wire 34 are located between the solenoid valve mounting component 32 and the solenoid valve body 31. Through the structural design of the silicon steel 33 and the enameled wire 34, the solenoid valve module 3 of this utility model has stable characteristics. For example, the enameled wire 34 uses copper as a conductor and is coated with different types of insulating varnish layers, possessing… It possesses excellent electrical conductivity and insulation properties and is heat-resistant up to 130°C. Furthermore, silicon steel 33 is non-oriented silicon steel 33, which can achieve higher magnetic induction under the same magnetic field. This means that the solenoid valve module 3 manufactured using it is smaller in size and weight, relatively saving on silicon steel 33 and insulation materials. Moreover, the stability of the resistance and inductance of the solenoid valve module 3 directly affects the electromagnetic force. These materials work together to influence the generation and dynamic response of the electromagnetic force. More specifically, silicon steel 33 is the magnetic core of the solenoid valve module 3, equivalent to a "dedicated channel" for the magnetic field. Its core function has two aspects: Concentrate the magnetic field and enhance the electromagnetic force: The magnetic field generated by the solenoid valve coil after it is energized will be concentrated and conducted through the iron core composed of silicon steel 33, avoiding the dispersion of the magnetic field, thereby forming a strong attraction at the armature 6, ensuring that the elastic force of the return spring can be quickly overcome and the valve core can be driven to move. Reduce energy loss and protect the coil: If ordinary steel is used instead of silicon steel 33, a large amount of eddy current and hysteresis loss will be generated when the magnetic field passes through, causing the iron core to overheat severely. This not only wastes electrical energy, but also burns the coil insulation layer and causes a short circuit. The low iron loss characteristics of silicon steel 33 can control the heat generation within a reasonable range and extend the life of the solenoid valve. The enameled wire 34 is a core component of the solenoid coil of the solenoid valve, which is equivalent to the "carrier for generating electromagnetic force". It is mainly used for conducting electricity to generate magnetic fields and for insulation to prevent short circuits.
[0019] This utility model controls the actual fuel output by axially moving the solenoid valve spring 11, thereby completing the opening and closing action of the fuel injector and accurately controlling the timing, quantity and pressure of fuel injection.
[0020] This embodiment does not impose any limitation on the shape, material, structure, etc. of this utility model. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of this utility model shall fall within the protection scope of this utility model.
