[0005] Furthermore, a columnar filter element is arranged inside the third straight tube.

[0006] Furthermore, the filter element is made of filter cotton.

[0007] Furthermore, the first straight pipe, the second straight pipe and the third straight pipe are threadedly connected.

[0008] Furthermore, the connecting pipe is threadedly connected to the lubricating oil tank.

[0009] Furthermore, the first straight pipe is perpendicular to the lubricating oil tank, and the first straight pipe and the second straight pipe are parallel.

[0010] The utility model provides a connecting pipe with two bent sections, and can use the deflection principle of streamlines to change the travel route of oil and gas, so that the oil in the oil-gas mixture is hindered at the bend and flows back to the lubricating oil tank; by providing a filter element, the oil can be further filtered, and the filtered oil flows back to the lubricating oil tank, thereby avoiding the accumulation of oil and dirt and waste of oil at the exhaust port; by threading the first straight pipe, the second straight pipe and the third straight pipe, the connecting pipe can be easily disassembled and cleaned, and the filter element can also be easily disassembled.
