Detailed Description
The following will be described in detail with reference to the specific embodiments of the present invention to help those skilled in the art to understand the technical solution of the present invention more completely, accurately and deeply.
Example 1
As shown in fig. 1 to 3, the oil-gas separation baffle structure of the present embodiment includes a bottom plate 10, an oil dropping hole 40, a membrane 20, and a baffle cover 30 provided on a lower surface of a separation baffle 50. The upper end of the oil dropping hole passage 40 is communicated with the bottom plate 10, a vertical oil dropping hole 41 is arranged in the oil dropping hole passage 40, an opening 42 is arranged at the lower end of the oil dropping hole passage 40, the opening 42 is communicated with the oil dropping hole 41, the diaphragm 20 is arranged on the opening 42, and the diaphragm 20 is fixed at the lower end of the oil dropping hole passage 40 through the baffle cover 30. The diaphragm 20 comprises a circular spring steel 21, and an annular groove 22 is formed in the middle of the circular spring steel 21, and the width of the annular groove 22 may be designed to be 0.2-1.0 mm, for example, may be designed to be 0.5 mm.
In the oil-gas separation baffle structure of the embodiment, after the oil-gas mixture in the crankcase is separated, the separated engine oil falls onto the bottom plate 10 and then enters the oil falling hole 40 to be blocked by the membrane 20, when the oil level is accumulated to a certain height, a sufficient pressure difference is generated inside and outside the membrane 20, the membrane deforms, and the engine oil flows back into the bottom shell from the annular groove of the membrane 20. This embodiment is through increasing an elastic diaphragm as the check valve at the oilhole lower extreme that falls for machine oil can normally flow back, has reduced machine oil consumption.
For those skilled in the art, the specific embodiments are only exemplary descriptions of the present invention, and it is obvious that the present invention is not limited by the above-mentioned manner, and various insubstantial improvements are all within the protection scope of the present invention as long as the technical solution of the present invention is adopted.
