〔産業上の利用分野〕
本発明は、給油装置で自動車への給油を行う場
合の給油方法に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a refueling method for refueling an automobile using a refueling device.
このような給油装置として、自動閉鎖ノズルバ
ルブを備えたものが知られている。
As such a refueling device, one equipped with an automatically closing nozzle valve is known.
例えば実公昭36−17872号公報では、弁開放用
引金を係止するダイヤフラムの室と導管途中の狭
隘部と導管先端外側面の３者を以て連結したノズ
ルバルブに於いて上記狭隘部に接して抵抗弁を設
け之れと一体の円錐体を狭隘部に介在させた自動
閉鎖ノズルバルブの構造が示されている。 For example, in Japanese Utility Model Publication No. 36-17872, in a nozzle valve that is connected by three parts: a diaphragm chamber that locks a valve opening trigger, a narrow part in the middle of the conduit, and the outer surface of the tip of the conduit, The construction of a self-closing nozzle valve is shown in which a cone integral with the resistance valve is interposed in the constriction.
これによれば、引金が引かれずにいれば弁は閉
じており液体は流通していないが、引金を引けば
その先端を軸支している摺動杆は小球を介して係
止杆によつて係止されているから引金は軸着部を
軸として擺動し弁杆を介して弁をバネに抗して押
し上げ液は弁部を通り更に抵抗弁を押し開いて流
れ導管の先端から流出しタンク内に溜まる。 According to this, if the trigger is not pulled, the valve is closed and no liquid flows through it, but if the trigger is pulled, the sliding rod that supports the tip of the valve is locked via a small ball. Since the trigger is held in place by a rod, the trigger slides around the shaft-mounted part, and the liquid pushes up the valve against the spring through the valve rod, and then pushes the resistance valve open and flows into the flow conduit. It flows out from the tip and collects in the tank.
この際狭隘部を流れる液によつてこの個所に開
口している連管内にはベルヌイの法則によつて陰
圧が生ずるけれども連管の他端は導管の先端外側
面より大気中に開口している為ダイヤフラム室内
には陰圧が加わらずダイヤフラムは動作しない。 At this time, due to the liquid flowing through the narrow part, a negative pressure is generated in the connecting tube that opens at this point according to Bernoulli's law, but the other end of the connecting tube opens into the atmosphere from the outer surface of the tip of the conduit. Because there is no negative pressure inside the diaphragm chamber, the diaphragm does not operate.
タンク内に液が溜まり液面が次第に上昇して導
管先端に開口している連管を閉鎖すると連管内に
生じている陰圧はダイヤフラム室のダイヤフラム
に作用しこれを吸引しダイヤフラムをバネに抗し
て湾曲させ之と一体の係止杆は移動する。 When liquid accumulates in the tank and the liquid level gradually rises, closing the connecting tube that opens at the tip of the conduit, the negative pressure generated in the connecting tube acts on the diaphragm in the diaphragm chamber, sucks it, and causes the diaphragm to resist against the spring. The locking rod, which is integral with the curved locking rod, moves.
係止杆が移動すると小球による摺動杆の係止は
解かれるものですでに引金には弁杆を介してバネ
の弾力が加わつている為摺動杆の係合が解かれる
と引金の先端は降下し同時に弁も降下して自動的
に流路を閉じる。 When the locking rod moves, the locking of the sliding rod by the small ball is released, and since the spring elasticity is already applied to the trigger via the valve rod, the trigger is released when the sliding rod is released. As the gold tip descends, the valve also descends and automatically closes the flow path.
また、特開昭52−145828号公報には給液ノズル
の先端へ光学的油面検知装置を設け、その出力を
もつて弁の開閉を司どらせた給油装置が示されて
いる。油面が上昇してこれを光学的油面検知装置
が検知すると、その出力でノズルバルブ内の弁を
自動的に閉じるものである。 Further, Japanese Patent Application Laid-Open No. 52-145828 discloses an oil supply device in which an optical oil level detection device is provided at the tip of a liquid supply nozzle, and the output thereof is used to control the opening and closing of a valve. When the oil level rises and the optical oil level detection device detects this, the output automatically closes the valve inside the nozzle valve.
しかし、特開昭52−145828号公報にある自動閉
鎖ノズルバルブでは、光学的油面検知装置が給面
時に発生する泡でも作動してしまい、泡のために

時の油の溢れを防ぐ操作を行わなければならな
い。
However, in the automatic closing nozzle valve disclosed in Japanese Patent Application Laid-Open No. 52-145828, the optical oil level detection device is activated even by bubbles generated at the surface of the oil supply, and oil supply often stops midway due to the bubbles. , there is an inconvenience that refueling must be performed several times.
Also, the one published in Utility Model Publication No. 36-17872 is also
In the case of the one in Publication No. 145828, the discharge amount is the same even when the valve closes and does not decrease, so when refilling near full, manually lower the flow rate to prevent oil overflow when the nozzle valve is stopped. must be carried out.
本発明の目的は前記従来例の不都合を解消し、

In the refueling system, the vehicle is provided with an oil level gauge having a coupling as an oil level output means of the fuel tank, and the refueling system is provided with a coupling connected to the coupling of the oil level output means, and the oil level is Based on the oil level data in the fuel tank of the meter, the control circuit speeds up the rotation of the pump motor of the refueling device when the amount of oil in the fuel tank is low, and slows it down when the fuel tank is almost full. The gist of this is to control the operation in stages so that the engine stops when the engine stops.

According to the present invention, when refueling a car's tank gasoline, as the refueling level in the tank increases, the rotational speed of the pump is reduced according to the output of the oil level gauge, thereby reducing the discharge amount from the nozzle valve and filling the tank. This will automatically stop the pump and stop refueling, allowing for a large discharge amount during refueling, allowing for efficient refueling, and when finishing refueling, the discharge amount will be small, so refueling will stop reliably.
以下、図面について本発明の実施例を詳細に説

伝え、ポンプ６は高速回転する。 Now, if there is almost no oil in the tank 2 of the car 1, the switch 4 at the lowest end moves away from the magnetic float 3, and a signal indicating that there is no oil is transmitted from the switch 4 to the control circuit 13. In response, the control circuit 13 transmits a high speed rotation signal to the motor 14, and the pump 6 rotates at high speed.
