The heat treatment process of anodic oxidation improves the hardness of its friction surface, it is ensured that valve pocket or spool are not in different during the motion
Often abrasion, the cost that can also directly result in OCV Oil Control Valve in this way increase.
Existing valve pocket and valve core structure (sliding valve structure), since valve pocket and spool are precision-fit, OCV Oil Control Valve exists
The cleannes of machine oil are required in actual application very high.And engine or vehicle are in use, due to each components
Between friction, can inevitably have subtle metallic particles in machine oil.To prevent valve pocket and spool clamping stagnation, it is ensured that OCV Oil Control Valve
It works normally, can additionally increase a strainer at the oil inlet of valve pocket, can also lead to OCV Oil Control Valve cost indirectly in this way
Increase.
Summary of the invention
