【考案の詳細な説明】
本考案は一般的には内燃エンジンのためのエアクリーナ
に関し、更に詳細には第１段階として取外し自在のカバ
ーに遠心式予備クリーナを兼用させたものと、第２段階
として円筒形乾式エレメントを有する簡易型二段式エア
クリーナにおいて、カバーに配設する複数個の空気流入
口に関する。[Detailed description of the invention] The present invention generally relates to an air cleaner for an internal combustion engine, and more specifically, the first stage is an air cleaner in which a removable cover doubles as a centrifugal pre-cleaner, and the second stage is an air cleaner that combines a removable cover with a centrifugal standby cleaner. The present invention relates to a plurality of air inlets disposed in a cover of a simple two-stage air cleaner having a cylindrical dry element.
従来この種のエアクリーナにおいては、コンパクトで簡
易型というのが特長であることより、カバーに配設する
複数個の空気流入四個々の大きさはある程度の制約を受
け、このためできるだけ数多く設けた場合でもその開口
部面積の合計はエアクリーナ出ロチューブ内径面積の４
０％程度に過ぎず、空気流入口の吸入抵抗は高くなる。Conventionally, this type of air cleaner has been characterized by being compact and simple, so the size of each of the multiple air inlets installed on the cover has been limited to some extent, so it has been difficult to install as many as possible. However, the total opening area is 4 of the inner diameter area of the air cleaner exit tube.
It is only about 0%, and the suction resistance at the air inlet becomes high.
一般的にエンジンに対する吸入抵抗の限界値はエアクリ
ーナエレメントの目詰まりにより増加する抵抗の限界で
決まるが、これには初期抵抗も含まれるため吸入抵抗が
高い場合はエレメントの目詰まりライフが短かくなり、
エレメントを清掃または交換する頻度が多いという欠点
があった。Generally, the limit value of the intake resistance to the engine is determined by the limit of the resistance that increases due to clogging of the air cleaner element, but this also includes the initial resistance, so if the intake resistance is high, the life of the element will be shortened due to clogging. ,
There was a drawback that the element had to be cleaned or replaced frequently.
本考案は以上の欠点を解消するため、従来型の構造を逸
脱することなく空気流入口のみを改良することによって
、コンパクトで簡易型という特長を失うことなく吸入抵
抗を低減し、エレメントの目詰まりライフを延長させよ
うとするものである。In order to eliminate the above-mentioned drawbacks, this invention improves only the air inlet without departing from the conventional structure, thereby reducing suction resistance without losing the features of being compact and simple, and preventing element clogging. It is intended to extend life.
以下に図面を参照しながら詳細な説明をする。A detailed explanation will be given below with reference to the drawings.
第１図は従来の簡易型エアクリーナの一例で、その破断
側面図を示し、第２図はその破断上面図を示す。FIG. 1 shows an example of a conventional simple air cleaner, a cutaway side view thereof, and FIG. 2 a cutaway top view thereof.

グ状に複数個配設されている。The upper surface of the cover 2, which is tightly fitted over the open upper end of the cylindrical housing 1 and screwed onto the yoke tip 3 by means of a wing nut 4, meets the annular air passage 6 between the element 5 and the inner wall of the housing. For part 7,
A plurality of air inlets 8 formed based on slot processing are arranged in a ring shape.
第３図にその空気流入口８の縦断面図を示す。FIG. 3 shows a longitudinal sectional view of the air inlet 8.
吸入に際し旋回流を起こさせるようにスロット部の一端
９を陥没させた半円すい形１１としているため、流入口
の開口部形状はほぼ半円形に成形されている。Since one end 9 of the slot portion is formed into a depressed semiconical shape 11 to generate a swirling flow during suction, the opening of the inlet is formed into a substantially semicircular shape.

の空気通路６を通り旋回流となって下方へ向かう。When the engine is started, air is sucked in from the outlet tube 12 of the air cleaner, but at this time, the air flowing in from the air inlet 8 passes through the annular air passage 6 between the element 5 and the inner wall of the housing 1, forming a swirling flow downward. Head to.

４へ至る。Heavy particles in the dust contained in the air fall along the inner circumference of the housing due to centrifugal force, and finally reach the dust outlet 1.
3, the dust chamber 1 is fixed to the bottom of the housing.
Leading to 4.
溜められたダストは溜め室１４へ装嵌された弾性体排出
弁１５によって周期的に外方へ排出される。The accumulated dust is periodically discharged to the outside by an elastic discharge valve 15 fitted into the reservoir chamber 14.

の空気流入口１６の縦断面図を示す。FIG. 4 shows a top view of the cover of the present invention, and FIG. 5 shows a vertical sectional view of the air inlet 16.

低くなるというものである。The air inlet 16 has the conventional shape described above, that is, the semiconical recessed shape 11, but the remaining end 10 of the slot processing is raised up in the opposite direction to the recessed shape, and a semiconical shape 17 is added. The area is larger than the opening area by the amount of the raised shape, so the suction resistance is lower than that of the conventional one.
第６図に本考案の応用例としてのカバー単体図を示し、
第７図にその空気流入口１８の縦断面図を示す。Figure 6 shows a single cover as an application example of the present invention.
FIG. 7 shows a longitudinal sectional view of the air inlet 18.

である。This is an example of the purpose of lowering the suction resistance even further than that of the above-mentioned device, and instead of slotting, a square hole 19 is provided,
By providing the semiconical recessed shape 11 and the semiconical raised shape 17 on both sides of the square hole, the area of the opening can be made larger than that based on the slot processing shown in FIG. 6, and the suction resistance can be lowered. As a result, the clogging life of the element can be greatly extended compared to conventionally known elements.
