【考案の詳細な説明】
本考案は、燃料タンクと気化器間に介装される燃料コッ
クのストレーナに関するものである。[Detailed Description of the Invention] The present invention relates to a strainer for a fuel cock interposed between a fuel tank and a carburetor.
一般に自動二輪車においては、燃料の消費状態を運転者
に知らせるために、リザーブ管をもった燃料コックが燃
料タンクに備えられている。Generally, in a motorcycle, a fuel tank is provided with a fuel cock having a reserve pipe in order to notify the driver of fuel consumption status.
第１図は従来のこの種燃料コックの一例を示すもので、
同図に示すように従来においては、リザーブ管１全体が
信組２によって被覆されているため、信組２の毛細管現
象により常に信組室３内に燃料が充満し、リザーブ管１
が本来の役割をはたさないという不具合があった。Figure 1 shows an example of a conventional fuel cock of this type.
As shown in the figure, conventionally, since the entire reserve tube 1 is covered with the fuel tube 2, the fuel chamber 3 is always filled with fuel due to the capillary action of the fuel tube 2, and the reserve tube 1
There was a problem in that it did not fulfill its original role.
すなわち、運転による燃料消費によって燃料タンク４内
の燃料液面が、保留分液面５以下になっても、信組２の
下部が燃料中にあるため、毛細管現象によって燃料を吸
上げ信組室３内に燃料を充満させてしまうからである。In other words, even if the fuel level in the fuel tank 4 falls below the reserved liquid level 5 due to fuel consumption during operation, since the lower part of the credit union 2 is in the fuel, the fuel will be sucked up by capillary action and transferred into the credit union room 3. This is because the tank will be filled with fuel.
この結果、燃料タンク内の燃料が保留分以下の状態にな
っても運転者は気付かず、燃料補給の機会を失してしま
うという不具合がある。As a result, even if the amount of fuel in the fuel tank becomes less than the reserved amount, the driver does not notice this and loses the opportunity to refuel.
特にこのような現象は、信組２にごみ等が付着してきた
時に顕著に現われる。Particularly, such a phenomenon becomes conspicuous when dirt or the like adheres to the credit union 2.
本考案はこのような不具合を改良するもので、リザーブ
管用の信組室と保留分燃料給供用の）戸網室とを隔絶す
ると共に、両信組室をリザーブ管と一体に形成するとい
うきわめて簡単な構成により、燃料タンク内の保留分液
面を的確にとらえることができる燃料コックのストレー
を提供するものである。The present invention aims to improve these problems by separating the communication room for the reserve pipe from the door screen room (for supplying reserved fuel), and by forming both communication rooms integrally with the reserve pipe, which is an extremely simple method. The present invention provides a fuel cock stray that can accurately capture the retained liquid level in the fuel tank depending on the configuration.
以下、その構成等を図に示す実施例により詳細に説明す
る。Hereinafter, its configuration and the like will be explained in detail with reference to embodiments shown in the drawings.
第２図は本考案に係るストレーナを使った燃料コックの
正面図と縦断Ｂ−Ｂ側面図、第３図はストレーナの各部
横断面図である。FIG. 2 is a front view and longitudinal BB side view of a fuel cock using a strainer according to the present invention, and FIG. 3 is a cross-sectional view of various parts of the strainer.
これらの図にわいて、符号１１は燃料タンク４の底部に

１ｂと、切替えレバー１１ｃおよび気化器に接続される
燃料供給口ｌｉｄ等が設けられている。In these figures, reference numeral 11 indicates a fuel cock installed at the bottom of the fuel tank 4, and this fuel cock 11 is connected to the engine carburetor when the fuel 5' in the tank is at a liquid level of 5 or more. The first fuel passage 11a is connected to the second fuel passage 1, which is communicated with the first fuel passage 11a when the reserved liquid level becomes 5 or less.
1b, a switching lever 11c, a fuel supply port lid connected to the carburetor, and the like.

ザーブ管１５ａの側部に隣接し一体に形成された第２の
信組室１５ｃとより構成されている。Reference numeral 15 denotes a strainer installed vertically above the fuel cock 11, and this strainer 15 includes a reserve pipe 15a connected to the first fuel passage 11a, and a first strainer provided on the upper open end of the reserve pipe 15a. and a second credit chamber 15c connected to the second 15b fuel passage 11b and integrally formed adjacent to the side of the reserve pipe 15a.
１５ｂ′および１５０′は第１の信組室１５ｂと第２の
信組室１５ｃを形成する信組で、それぞれリザーブ管１
５ａと一体に形成された保持部材１５ｄ等によって保持
されている。15b' and 150' are credit unions forming a first credit union room 15b and a second credit union room 15c, and each has a reserve pipe 1.
It is held by a holding member 15d etc. formed integrally with 5a.
１５ｅは第１の信組室１５ｂと第２の信組室１５ｃとを
隔絶するごとくリザーブ管１５ａの開口端に隣接して一
体に設けた仕切板、１６は第１の戸網室１５ｂの上端部
を閉塞する蓋体である。Reference numeral 15e denotes a partition plate integrally provided adjacent to the open end of the reserve pipe 15a to isolate the first credit union room 15b and the second credit union room 15c, and 16 denotes a partition plate provided at the upper end of the first door screen room 15b. It is a lid that closes.
したがって、図に示すようにストレーナ１５が燃料タン
ク４内に臨むように燃料コック１１を装着し、切替レバ
ー１１ｃをＯＮの位置に設定してわけば、タンク内燃料
５′が保留分液面５以上あるときは、第１の信組室１５
ｂとリザーブ管り５ａ内を通って燃料が供給される。Therefore, as shown in the figure, if the fuel cock 11 is installed so that the strainer 15 faces into the fuel tank 4 and the switching lever 11c is set to the ON position, the fuel 5' in the tank will be transferred to the reserved liquid separation surface 5. If there are more than
Fuel is supplied through the reserve pipe 5a.
一方、タンク内燃料が消費されその液面が保留分液面５
以下になると燃料の供給が停止し、したがって、エンジ
ンも停止するからこれによって運転者は燃料の残量が保
留分しかないことを知る。On the other hand, the fuel in the tank is consumed and its liquid level is the reserved liquid level 5.
If the fuel level drops below this level, the fuel supply will stop and the engine will also stop, so the driver will know that only the reserved amount of fuel is left.
そこで運転者は切替レバー１１ｃをＲＥＳ側に切替え、
第２の信組室１５ｃを燃料供給口１１ｄに連通させ、保
留分燃料を使用しながら運転し燃料の補充を行なうべく
準備する。Therefore, the driver switches the switching lever 11c to the RES side,
The second credit union room 15c is communicated with the fuel supply port 11d, and preparations are made to operate while using the reserved fuel and to replenish the fuel.
以上説明したように本考案によれば、第１の信組室と第
２の信組室がそれぞれリザーブ管の上方と側部に一体に
設けられているから小型に形成でき、また両信組室間は
仕切板によって隔絶されているから保留分燃料が第１の
信組室に導入されるようなことがない。As explained above, according to the present invention, since the first credit union room and the second credit union room are provided integrally above and on the side of the reserve pipe, it can be formed compactly, and the space between the two credit union rooms is Since it is isolated by the partition plate, there is no possibility that the reserved fuel will be introduced into the first credit union room.
したがって燃料タンク内における保留分液面を的確にと
らえ、それを運転者に知るせることかできる。Therefore, the retained liquid level in the fuel tank can be accurately determined and the driver can be made aware of it.
また、各信組室を形成する信組はリザーブ管、仕切板お

全体がユニット化されているため組付けもしやすいとい
う利点もある。In addition, the credit unions forming each credit union room are held by a reserve pipe, a partition plate, and a holding member, and since the partition plate and the holding member are integrally formed with the reserve pipe, deformation of the credit union can be prevented. It has the advantage of ensuring a sufficient filtration area, minimizing the number of parts, and being easy to assemble since the entire unit is made into a unit.
