【発明の詳細な説明】 〔産業上の利用分野〕 この発明は給油キャップを取外すことなく給油できる
カートリッジタンクに係るものである。DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a cartridge tank capable of refueling without removing a refueling cap.
従来カートリッジタンクは弁付の給油キャップを取付
け、給油キャップを外して給油した後で給油キャップを
締め、油タンクの受皿に転倒装着することによって給油
キャップの弁が開き、油タンクで使用された油量がカー
トリッジタンクから補給されるものである。Conventional cartridge tanks have an oil cap with a valve, remove the oil cap, refuel the oil, close the oil cap, and turn it over to the oil tank tray to open the oil cap valve and use the oil used in the oil tank. The amount is supplied from the cartridge tank.
この為給油の時カートリッジタンクのみ取出して作業
を行うから使い勝手が良くなったが、弁付キャップをし
っかり締付けておかないと転倒時に給油キャップが外れ
多量の油を一度に流出させるトラブルがあった。For this reason, at the time of refueling, only the cartridge tank is taken out and the work is performed because the work is performed.
上記の問題点はカートリッジタンクへの給油時にキャ
ップを取外す必要がある為で、このトラブルを防ぐ構造
として実公昭47−42023号が知られている。The above problem is due to the need to remove the cap when refilling the cartridge tank, and Japanese Utility Model Publication No. 47-42023 is known as a structure for preventing this trouble.

By making the inside of the inner cylinder 4 an air flow path 11, the lower end of the inner cylinder 4 is set to a full oil position. Reference numeral 19 denotes an air hole formed in the side wall of the inner cylinder 4, and reference numeral 20 denotes a projection projecting from the bottom of the outer cylinder 1. After the oil supply is stopped, the siphon valve 25 of the refueling tank 13 is opened and then the inner cylinder 4 is pushed. The air release valve 21 is separated from the air hole 19 by 20 so that the air in the cartridge tank 3 can be released. 27
Is a movable stopper provided on the refueling joint 14, and regulates a refueling position and an air release position.

ても弁部などのせまい流路に届くことはほとんどなく、
エアロックが起る恐れは全くなくなった。According to the present invention having the above construction, the valve seat 6 facing the on-off valve 7 is attached to the inner wall of the inner cylinder 4, and the valve seat 2 facing the valve 5 on the outer wall of the inner cylinder 4 is attached to the outer cylinder 1 attached to the cartridge tank.
Since they are provided on the inner wall, the flow path in the inner cylinder 4 and the flow path in the gap 10 between the outer and inner cylinders 1 and 2 have valve portions, respectively. For this reason, the refueling joint 14 attached to the outer cylinder 1 connects the refueling pipe 26 to the inside of the inner cylinder 4 or to the gap 10, and can refuel the cartridge tank 3 via one valve portion. There is an air flow passage 11 partitioned by the inner cylinder 4 with respect to an oil flow passage 12 through which oil passes during refueling.
Since the flow path is widened on the way to the valve section that forms the narrowest flow path, even when oil droplets at the time of refueling are directed to the air flow path 11, they hardly reach the narrow flow path such as the valve section. ,
The risk of an airlock is gone.

押圧してもよく、この場合外・内筒１・４の間隙10が空
気流路11となり、内筒４内が油流路12となる。On the other hand, in the tray 16 of the oil tank 15 in which the cartridge tank is mounted, there is no danger of causing air lock because the flow passage passing through the valve portion is small even if either the inner cylinder valve 5 or the opening / closing valve 7 is opened. It becomes fully usable. But saucer 16
The opening / closing valve 7 and the inner cylinder 4 may be simultaneously pressed by providing a push shaft 17 and a cylinder 18. In this case, the gap 10 between the outer and inner cylinders 1 and 4 becomes the air flow path 11, and the inner cylinder 4 is filled with oil. It becomes the channel 12.

給油することができる。Further, in a configuration in which the inner cylinder 4 separates the air flow path 11 and the oil flow path 12, if the inside of the inner cylinder 4 is set to be the air flow path 11, the end of the inner cylinder 4 is immersed in oil during refueling. When this occurs, the air in the cartridge tank cannot be discharged, and refueling stops at the oil level. Therefore, if the siphon effect is stopped by opening the siphon valve 25 of the oil tank 13 and the oil level is changed by an operation such as slightly tilting the cartridge tank 3, air can be discharged from the inner cylinder 4,
The oil remaining in the oil supply pipe 26 can be supplied to the cartridge tank 3. On the other hand, direct cartridge tank 3
Stopper 27 that was facing the outer cylinder 1
When the restriction on the outer cylinder 1 is released by pressing, the refueling joint 14 can be pushed further into the interior. The inner cylinder 4 is a refueling joint
When pressed down by 14, the pressure contact between the air vent valve 21 of the inner cylinder 4 and the air hole 19 is released, so that the air in the cartridge tank 3 can escape from the air hole 19 into the inner cylinder 4, and the oil supply pipe 26 The oil remaining in the cartridge tank can be supplied to the cartridge tank.
以上の様にこの発明では内筒４を境に空気流路11と油

ステムのようにたびたびエアロックを起すトラブルが防
止できた。As described above, in the present invention, the air flow path 11 and the oil flow path 12 are made independent from each other with the inner cylinder 4 as a boundary, and both the flow paths 11 and 12 are provided with valves. This prevents the problem of frequently causing air locks as in the conventional system that refuels without removing the refueling cap without reaching the valve section of the road 11.
また空気流路11と油流路12を独立させたので油の流れ
に空気が絞らなくなり給油速度が向上したものである。Further, since the air flow path 11 and the oil flow path 12 are made independent, the air is not restricted to the oil flow, and the oil supply speed is improved.

ートリッジタンク３をあふれさせて周囲をよごしてしま
うトラブルが防止できたものである。On the other hand, when the inside of the inner cylinder 4 is used as the air flow path 11, if the end of the inner cylinder 4 is immersed in the oil, the air cannot be discharged from the cartridge tank 3 and the refueling thereafter is stopped. For this reason, it is possible to prevent a trouble that the operator overflows the cartridge tank 3 and smudges the surroundings.

16を使えば空気流路11と油流路12が独立でき、多量の油
が急速に流れる油タンク15が空量の時にもエアロックの
トラブルが起る恐れはない。Further, when the cartridge tank 3 is mounted on the oil tank 15 such as an oil stove, the on-off valve 7 can be opened only by slightly increasing the length of the push shaft 17 of the pan 16, so that it can be used as in conventional products. Also, when the cartridge tank 3 is mounted on the pan 16, a pan on which the inner cylinder 4 is pressed is formed.
If the oil passage 15 is used, the air flow path 11 and the oil flow path 12 can be independent from each other, so that even when the oil tank 15 through which a large amount of oil flows rapidly is empty, there is no possibility that an air lock trouble will occur.
