The fine separation shell is a plastic shell. The lower part of the outer side surface of the fine separation shell is provided with an oil return hole 1.1. The fine separation pipeline is a plastic pipeline. The fine separation shell is connected with the fine separation pipeline through a buckle. The outer side surface of the fine separation pipeline is provided with a plurality of bulges.
The fine separation cotton layer is a fiber cotton layer. The refined separation cotton layer is cylindrical. The inner side face of the fine separation cotton layer is tightly abutted against the outer side face of the fine separation pipeline, and the outer side face of the fine separation cotton layer is tightly abutted against the inner side face of the fine separation shell.
As shown in fig. 1 and 2, one port of the fine separation pipeline is an oil gas inlet 2.1, and the other port of the fine separation pipeline is an exhaust port 2.2. The fine separation pipeline sequentially comprises an air inlet section pipeline 2a, a separation section pipeline 2b and a pressure release section pipeline 2c, and the air inlet section pipeline, the separation section pipeline and the pressure release section pipeline are sequentially distributed from an oil gas inlet to an exhaust port. The separation section pipeline is provided with a plurality of oil gas through holes 2.3 penetrating through the inner side surface and the outer side surface of the separation section pipeline.

The self-adaptive differential pressure regulating mechanism of the embodiment can regulate the airflow passing area of the oil-gas separator according to the working pressure change in the crankcase, and as the working pressure in the crankcase increases, the sealing ball moves towards the exhaust port, so that the number of the oil-gas through holes between the sealing ball and the oil-gas inlet increases (namely, the airflow passing area entering the fine separation cotton layer from the fine separation pipeline is increased), thereby slowing down or avoiding the increase of the working pressure in the crankcase and the oil-gas separator;
