In the preferred embodiment of the utility model, above-mentioned baffle extends across in tonifying Qi tube shell from the development length of side wall
The center line of chamber, the length stretched from one side wall can block the length of the baffle extended from opposing sidewalls.
What the utility model reached by adopting the above technical scheme has the technical effect that Oil-gas Separation function may be implemented in blowdown pipe
Can, it allows machine oil to come back in oil sump, guarantees engine health, reduce specific oil consumption.
The above description is merely an outline of the technical solution of the present invention, in order to better understand the skill of the utility model
Art means, and being implemented in accordance with the contents of the specification, and in order to allow the above and other purpose, feature of the utility model
It can be more clearly understood with advantage, it is special below to lift preferred embodiment, and cooperate attached drawing, it is described in detail.
Detailed description of the invention
Fig. 1 is the connection and mounting structure schematic diagram of the utility model blowdown pipe.
Specific embodiment
Further to illustrate that the utility model is the technical means and efficacy reaching predetermined purpose of utility model and being taken,
The embodiments of the present invention are described below in detail, examples of the embodiments are shown in the accompanying drawings, wherein identical from beginning to end
Or similar label indicates same or similar element or element with the same or similar functions.Pass through specific embodiment
Illustrate, when can be to the utility model reach the technical means and efficacy that predetermined purpose is taken be able to it is more deeply and specific
Understand, however institute's accompanying drawings are only to provide reference and description is used, and are not used to limit the utility model.
Fig. 1 is the connection and mounting structure schematic diagram of the utility model blowdown pipe；As shown in Figure 1, a kind of blowdown pipe 10, if
It sets before automobile compressor, the blowdown pipe 10 includes tonifying Qi tube shell 16, and one end of tonifying Qi tube shell 16 goes out equipped with blowdown pipe
Port 12, the other end are equipped with blowdown pipe air inlet 18；Baffle 14 is additionally provided in the tonifying Qi tube shell 16 of the blowdown pipe 10；Institute
Stating blowdown pipe gas outlet 12 needs to connect with air inlet pipe 30 upward, and blowdown pipe air inlet 18 needs to connect with vehicle crankcase 20 downward.
Oil gas enters blowdown pipe 10 from crankcase 20, stops layer by layer by the baffle 14 being arranged in blowdown pipe 10, the machine oil in oil gas
Grain is largely separated.
Crankcase 20 includes oil sump；Oil gas enters from blowdown pipe air inlet 18, by the isolated machine oil of blowdown pipe 10
Grain returns to the oil sump of crankcase 20 from blowdown pipe air inlet 18, so blowdown pipe air inlet 18 is oil return opening.Rest on tonifying Qi
