Embodiment Construction

[0026] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0027] Such as Figure 5-7 As shown, an automobile engine oil control valve in this embodiment at least includes a valve body 1, a valve core 2 and an electromagnetic coil 3, and the valve body 1 is provided with a late angle oil port 11, an oil inlet port 12, and an oil supply port 13. And two oil discharge ports 14. in Figure 5 Shown is the structural schematic diagram of the automobile engine oil control valve in the state of returning oil to the oil chamber at the late angle and filling the oil chamber at the advancing angle of the automobile engine oil control valve in this embodiment. Fi...

Abstract

The invention relates to the technical field of a control valve and specifically discloses an automobile engine oil control valve. In comparison with an engine oil control valve of the prior art, the automobile engine oil control valve disclosed by the invention is capable of realizing sealing by virtue of a sealing sleeve, reducing the surface machining precision and assembly precision of a valve core and a valve body and lowering the production cost; an elastic part for providing pre-tightening force is arranged between the sealing sleeve and a sealing nut; the pre-tightening force can be adjusted by rotating the sealing nut so as to adjust the resistance in the motion process of the valve core; after the sealing sleeve is slightly abraded, the sealing nut can be rotated to press down the sealing sleeve so as to make the sealing sleeve again play a sealing effect, so the service life of the engine oil control valve is prolonged, and the frequency for replacing the engine oil control valve is reduced; the sealing sleeve can just be replaced even after being abraded seriously; in comparison with the engine oil control valve, which is replaced directly, of the prior art, the automobile engine oil control valve disclosed by the invention is lower in replacement cost.

Description

technical field [0001] The invention relates to the technical field of control valves, in particular to an automobile engine oil control valve. Background technique [0002] figure 1 Shown is a schematic structural diagram of an existing automobile oil control valve, which at least includes a valve body 1, a valve core 2 and an electromagnetic coil 3, wherein the valve body 1 is provided with an oil inlet port connected to an oil inlet chamber 12. The delayed angle oil port 11, oil supply port 13 and two oil discharge ports 14 connected to the delayed angle oil chamber, such as figure 2 As shown, the delayed angle oil port 11, the advanced angle oil port 12, the oil supply port 13 and the two oil discharge ports 14 are special-shaped holes penetrating the valve body wall. [0003] In the above-mentioned prior art automotive oil control valve, the sealing between the valve body and the valve core is mainly guaranteed by the machining accuracy and assembly accuracy of the s...
