Description

【考案の詳細な説明】この考案は、エンジンに用いるエアークリーナ
の吹返しオイル抜取り装置に関する。[Detailed Description of the Invention] This invention relates to a blowback oil removal device for an air cleaner used in an engine.

エンジンでは、吸気管に連結した気化器の入口
にエアークリーナを連結して、清浄な空気が吸入
できるようにしている。エンジンの吸気は、間欠
的に急激に行われるので、吸入した反動で、その
後に吹返しがあり、エアークリーナの内側の室
が、吹返したガス中の燃料やオイル分で汚れる。
これをパイプで、クリーナの外に抜くようにして
いるが、オイルが抜ける代りに、水分や塵が入つ
て具合が悪い。 In an engine, an air cleaner is connected to the inlet of a carburetor connected to the intake pipe so that clean air can be taken in. Since the engine takes in air intermittently and rapidly, the reaction from the intake causes blowback, and the inner chamber of the air cleaner becomes dirty with fuel and oil in the blowback gas.
I try to drain this out of the cleaner using a pipe, but instead of the oil coming out, moisture and dust get in, making it uncomfortable.

この考案は、かかる点に鑑み改善したもので、
以下図面に示す本考案の実施例について説明す

Embodiments of the present invention shown in the drawings will be described below.

１の下端には、水抜き孔１０を設ける。 The left and right outer casings 1 are provided with suction ports 2 on their upper sides. Then, it is integrally connected to the left and right sides of the inner casing 3.
The lower surface of the inner casing 3 is located higher than the lower surface of the outer casing 1. The inner case 3 has an outlet 4 at the front end and a vaporizer 5.
Connect to. Window holes 6 are provided on the left and right side surfaces of the inner casing 3 to communicate with the outer casing 1, and a cleaner element 7 is stretched over the window holes 6. Inner case 3
There is an oil drain hole 8 on one side of the lower end that leads to the outer casing 1.
is provided, and the porous body 9 is inserted. Further, drain holes 10 are provided at the lower ends of the left and right outer casings 1.

作用について説明する。 The effect will be explained.

吸気は、吸入口２から左右の外筐１内に入る。
そして、クリーナエレメント７で濾過されて窓孔

のを防いでいる。 Intake air enters the left and right outer casings 1 through the intake ports 2.
Then, it is filtered by the cleaner element 7, enters the inner casing 3 through the window hole 6, and flows to the outlet 4. Although the inlet 2 is covered on the outside, when rainwater or the like enters the outer casing 1, it drains into the drain hole 10. Exit 4
The oil contained in the blowback gas flowing back into the inner casing 3 flows to the bottom surface of the inner casing 3, enters the outer casing 1 through the oil drain hole 8, and, like moisture, flows through the water drain hole. 10 to the outside. Drain hole 10
is located at a lower position than the oil drain hole 8, so moisture does not enter the inner casing 3 through the oil drain hole 8. Further, the porous body 9 prevents dust from entering the inner casing 3.

に長いホースを連結する必要もなくなる。 As explained above, this idea connects the left and right outer casings with an inner casing whose bottom surface is higher than the bottom surface of the outer casing, provides an outlet at the front end of the inner casing, and extends cleaner elements on the left and right sides of the inner casing. With ivy window holes,
An oil drain hole leading to the outer casing is provided on one side of the lower end of the inner casing, and a porous body is inserted into the hole, and a water drain hole is provided at the lower end of the outer casing. Once inside the outer casing, it passes through the drain hole and falls to the outside. Furthermore, since the lower surface of the outer casing is lower than the lower surface of the inner casing, water that has entered the outer casing does not enter the inner casing through the oil drain hole. Furthermore, dust is also prevented from entering the inner casing by the porous body inserted into the oil drain hole. In this way, there is no need to connect a long hose to the oil drain hole.
