Technical Field

[0001] The utility model relates to the field of spring seats for oil pressure control valves, in particular to a spring seat for an oil pressure control valve and an oil pressure control valve. Background Art

[0002] The existing engine lubrication system mainly includes an oil pump, an oil filter and an oil pump proportional valve. The goal of the lubrication system is to achieve the most ideal lubrication effect, that is, while meeting the basic lubrication requirements of the engine, it can also achieve the optimal energy consumption savings. The reliability and adjustment accuracy of the oil pump proportional valve directly determine the lubrication effect of the engine. The spring of the oil pump proportional valve acts in cooperation with the electromagnetic force to control the valve core at different target positions. Therefore, the requirements for the positioning reliability and initial position accuracy of the spring are very high.

[0003] There are various structures for the existing spring seats, but most of them are complex in structure, resulting in great processing difficulty and low positioning accuracy of the valve body supporting the spring seat. In addition, under vibration and thermal shock, the spring seat is prone to looseness and the positioning reliability is low.

[0004] Therefore, in view of the above existing technical problems, it is necessary to provide a new technical solution. Summary of the Utility Model

[0038] The additional aspects and advantages of the present utility model will be partly given in the following description, partly will become obvious from the following description, or will be understood through the practice of the present utility model.

[0039] Please refer to Figures 1-3 , as Figures 1-3 shown, on the one hand, the present utility model provides a spring seat for an oil pressure control valve. The spring seat 1 is installed in the valve body of the oil pressure control valve. The spring seat 1 includes a spring seat main body 10;

[0040] The spring seat main body 10 has a cylindrical structure. The spring seat main body 10 is provided with a thread 11 on its circumferential surface. One end surface of the spring seat main body 10 is a spring support surface 12. A spring positioning circle 13 for sheathing the spring is fixedly provided on the spring support surface 12. The spring seat main body 10 is axially provided with a through hole 14, and an adjusting structure 15 is provided on the side of the spring seat main body 10 away from the spring support surface 12.

[0041] In the example, the through hole 14 is used as an oil passage hole. Of course, this patent is not limited to this, and it can also be used for other purposes according to the actual situation. Setting the through hole as an oil passage hole enables the oil pump oil pressure control valve to integrate the oil drainage function.

[0042] In the example, one end of the through hole 14 is open and located within the spring positioning circle 13. Further preferably, the through hole 14 and the spring positioning circle 13 are coaxially arranged. In the example, the inner diameter of the through hole 14 is the same as the inner diameter of the spring positioning circle 13, and the spring positioning circle 13 is a spring positioning ring.

[0043] In a preferred embodiment, a plurality of positioning notches 16 are provided on the circumferential surface of the spring seat body 10. Among them, "a plurality" means one or more.

[0044] Further preferably, a plurality of positioning notches 16 are equidistantly provided on the circumferential surface of the spring seat body 10. In the example, 6 positioning notches 16 are equidistantly provided on the circumferential surface of the spring seat body 10. Of course, this patent is not limited thereto, and 1, 2, 3 or more etc. can be provided according to actual situations, and the length, height and depth of the positioning notches 16 can also be adjusted according to actual needs.

[0045] The positioning notches are provided to facilitate the installation of the oil pressure control valve. After the spring seat is installed in place, it holds the deformed valve body. Due to the spatial surplus of the positioning notches, axial positioning of the spring seat is achieved, and the oil pressure value and oil drainage capacity are stably fixed.

[0046] In a preferred embodiment, the adjusting structure 15 is a non-circular adjusting protrusion or a non-circular adjusting hole. In the example, the adjusting structure 15 is a non-circular adjusting hole. The non-circular adjusting hole includes but is not limited to cross-shaped, linear, triangular, rectangular, hexagonal or star-shaped, etc. Of course, this patent is not limited thereto, as long as the spring seat can be installed and twisted. Similarly, the non-circular adjusting protrusion is also based on being able to twist and rotate the spring seat, and will not be specifically listed one by one here. In the example, as Figure 2 shown, the non-circular adjusting hole is an internal hexagonal hole. The non-circular adjusting protrusion or non-circular adjusting hole is provided to facilitate the installation of the spring seat into the valve body through an adjusting tool, and the position of the spring seat can also be adjusted through the adjusting tool.

[0047] Preferably, the spring seat 1 is a plastic spring seat or a metal spring seat. In the example, the plastic spring seat is an injection-molded plastic spring seat. In the example, the metal spring seat is a processed metal spring seat.

[0048] On the other hand, as Figures 1-3 shown, the present utility model also provides an oil pressure control valve, which includes a valve body 2, a valve core 3, a spring 4 and the spring seat 1 as described in the above technical solution;

[0049] The valve body 2 is a hollow structure with at least one end open. A stop surface 21 is provided on the inner wall of the inner cavity of the valve body 2, and an internal thread is provided on the inner wall of one end of the valve body 2 close to the opening;

[0050] The valve core 3 is installed in the valve body 2. A limiting protrusion 31 is provided at the tail end of the valve core 3. The limiting protrusion 31 stops at the stop surface 21 in the valve body 2.

[0051] One end of the spring 4 is in contact with the tail end of the valve core, and the other end of the spring 4 is sleeved on the spring positioning circle 13 of the spring seat 1 and contacts the spring support surface 12;

[0052] The spring seat 1 is threadedly connected to the internal thread of the valve body 2 .

[0053] In the example, a spring groove is provided at the tail end of the valve core, and one end of the spring 4 is accommodated in the spring groove.

[0054] One end of the spring contacts the tail end of the valve core, and the other end of the spring 4 contacts the spring support surface. The spring support surfaces of the valve core and the spring seat limit the axial movement of the spring.

[0055] In the example, the inner diameter of the spring 4 is consistent with the outer diameter of the spring positioning circle 13. The other end of the spring is sleeved on the spring positioning circle, limiting the radial movement of the spring. One end of the spring is accommodated in the spring groove, which also limits the radial movement of one end of the spring.

[0056] In the example, the axial position of the spring seat in the valve body is adjusted by rotating the adjustment structure, so that the valve core has different initial positions, thereby realizing oil pressure regulation of the oil pump. By adjusting the different positions of the spring seat, the oil pump can be regulated in different oil pressure ranges.

[0057] It should be noted that, in the absence of conflict, all features in the above embodiments or embodiments described herein can be freely combined.

[0058] In the description of this specification, the description with reference to the terms "one embodiment", "some embodiments", "yet another embodiment", "another embodiment", "other embodiments", "example", "specific example" or "some examples" etc. means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the utility model.
