Detailed Description

The following detailed description of the embodiments of the present invention is provided in order to make the technical solution of the present invention easier to understand and understand.

Example (b):

a side-to-center mounted gas-oil separator is explained in that the gas-oil separator is laterally fixed to a vehicle when it is assembled to the vehicle, with reference to the orientation shown in FIGS. 1 and 2. The middle installation can be specifically the centre and can alternate and do not influence self function. The concrete structure, including curb plate drain pan 1 and curb plate lid 2, curb plate drain pan 1 and the concatenation of curb plate lid 2 are formed with inner chamber 3, air inlet 41 and gas outlet 42, and the middle part of curb plate drain pan 1 and curb plate lid 2 all is provided with isolation tube portion 43, and isolation tube portion 43 concatenation butt joint forms installation channel 431 on the inner wall. The separator tube 43 is located in the coarse filtration zone 31. Here, the installation channel 431 may be installed with a cooler pipe or other fixing member. The installation channel 431 is circular, and if a component such as a water pipe penetrates into the installation channel, the heat of the part of the oil-gas separator can be taken away, so that the cooling effect on the oil-gas separator is achieved. If the other is adopted, the oil-gas separator is convenient to fix and install.

As can be seen from fig. 2 and 3, the side panel bottom shell 1 is provided with a barrier 11, and the barrier 11 divides the inner cavity 3 into a coarse filtration area 31, an oil return area 32 and an air discharge area 33. A plurality of flow blocking clapboards 13 are distributed on the coarse filtration area 31, the air inlet 41 is positioned at the lower end of the side plate bottom shell 1, and the air inlet direction is vertical to the vertical surface of the side plate bottom shell 1.

The oblique angle position of enclosing the fender portion 11 is provided with cassette 12, is equipped with smart filtering component 5 on cassette 12, and smart filtering component 5 has the slope of slope to oil return region 32. The baffle part 11 is close to the side of the side plate bottom shell 1 and forms a zigzag backflow channel 14, and a cover plate 16 and an oil return pipe 15 are arranged at the lower end of the backflow conduction.

As can be understood by referring to fig. 3, the fine filter assembly 5 includes an air inlet partition plate 51 and an oil return plate 52, the air inlet partition plate 51 and the oil return plate 52 are inserted in parallel on the cartridge 12, the air inlet partition plate 51 is located below the oil return plate 52 and has a plurality of air inlet passages 511, outlet ends of the air inlet passages 511 are provided with protruding pipes 512, and the periphery of the area of the protruding pipes 512 is provided with protruding strips 513 with open lower ends. The angle of inclination of oil return plate 52 with the horizontal mounting surface ranges from 30 to 70 degrees. The present scheme is preferably 45 degrees or 60 degrees. The air inlet partition plate 51 is parallel to the oil return plate 52, oil liquid passes through the air inlet channel 511 and then is adsorbed and accumulated by the oil return plate 52, and in addition, the oil liquid can fall on the air inlet partition plate 51, and due to the design of the convex pipe 512 and the convex strip 513, the oil liquid is not easy to block the air inlet channel 511.

The PCV valve device 6 is connected to the air outlet 42 in a horizontally installed connection.

It can be seen that the assembly process is relatively simple by inserting the fine filter assembly 5 into the cartridge 12 and covering the side panel cover 2.

It is also easier to assemble on the car because installation passageway 431 is located the middle part to it all can to alternate pipe fitting or fixing base etc. on this installation passageway 431, then wholly can be fixed in the side direction mounted position of car, because satisfy the side direction installation when the structure of this scheme satisfies oil-gas separation's functional requirement, make oil-gas separation process compare in the past can be different.

Path process of oil and gas: oil gas can get into from the below position, through coarse filtration region 31, be enclosed fender portion 11 isolation and block, and oil gas can only enter into exhaust region 33 and oil return region 32 through smart filter assembly 5, exhaust region 33 is located the top, high temperature oil gas has the power that rises and can continue to rise the discharge, and the fluid granule is heavier, receive multichannel resistance after, can gather and the backward flow enters into oil return region 32 on smart filter assembly 5, thereby utilize gravity, and the separation path of the vertical direction who increases improves the oil-gas separation effect.

The coarse filter area 31 can block dust and part of oil, and the space is larger at the position where the separation pipe part 43 is arranged, so that the blocking effect of coarse filtering can be achieved, and the space of the separation pipe part 43 is increased. The air inlet direction can be from the side direction air inlet to can let dust and fluid gather in the bottom, be difficult for causing the jam of air inlet 41.

By utilizing the tortuous return passage 14, the oil liquid flows slowly, clean oil liquid can be quickly recovered, and the oil liquid containing impurities is easy to accumulate and can be attached to the wall of the return passage 14.

The addition of the horizontally installed PCV valve device 6 can improve the oil-gas separation reliability.

The above are only typical examples of the present invention, and besides, the present invention may have other embodiments, and all the technical solutions formed by equivalent substitutions or equivalent changes are within the scope of the present invention as claimed.
