Description
【考案の詳細な説明】 本考案は、電動噴霧器用ギヤポンプの改良に関する。[Detailed explanation of the idea] The present invention relates to an improvement of a gear pump for an electric sprayer.
一般に上記噴霧器用ギヤポンプＡは第１図のように液体
タンクイを有する噴霧器本体部分口に隔壁を介して収容
され、そしてその吸込口１をタンクイ内に連通させ又吐
出口２をコック八を有する柄付噴霧ノズル二に接続させ

給噴霧するもので、そして又この噴霧を中断する場合は
普通、コック八を閉止操作する関係上吐出口２と噴霧ノ
ズル二との間に当然圧力がか又る。Generally, the above-mentioned gear pump A for a sprayer is housed in an opening of a sprayer main body having a liquid tank via a partition as shown in FIG. The liquid sucked in by the drive of the gear pump A is supplied to the spray nozzle 2 under pressure through the discharge port 2, and when this spraying is interrupted, it is normal. When the cock 8 is closed, pressure naturally builds up between the discharge port 2 and the spray nozzle 2.
そのため従来では吐出口に別にホースを接続しこのホー
スを介して連結したバイパス弁を動作してタンクに逃が
してやる手段が採られてきたが、ホースなるが故に杭れ
易く、勿論ホース止金具を使用するも急激な圧力が働く
ためホースの接続部がゆるんだりしてホース外れの憂は
依然として解決されておらず、而もホース接続部が本体
内部にあるため、上記ホース外れを生じたときこれを接
続する操作が極めて煩雑且面倒なる不都合は避は難い。Conventionally, therefore, a separate hose was connected to the discharge port and a bypass valve connected via this hose was operated to allow the water to escape into the tank. Even after using the hose, the problem of the hose coming loose due to the sudden pressure exerted on it has not yet been resolved.However, since the hose connection is inside the main unit, when the hose comes loose, It is difficult to avoid the inconvenience that the operation of connecting the two is extremely complicated and troublesome.
そこで、この考案はギヤポンプそれ自体にバイパス弁を
一体に装置させ、もって従来のもつ不都合欠点を除去し
ようとするものである。Therefore, this invention attempts to eliminate the disadvantages of the conventional pump by integrating a bypass valve into the gear pump itself.
以下図面に就いて実権例の詳細を述べる。Below, we will discuss the details of actual rights regarding the drawings.
第２図は上記第１図に示したギヤポンプＡの分解斜面図
を示し、１は吸込口、２は吐出口、３はモータである。FIG. 2 shows an exploded perspective view of the gear pump A shown in FIG. 1, in which 1 is a suction port, 2 is a discharge port, and 3 is a motor.
そこで本考案の要旨構成は、上記ポンプＡのエンドプレ

止などによるポンプ内圧力の上昇によって開き動作し液
体をタンク内イに帰戻しするバイパス弁６を設けたもの
である。Therefore, the main structure of the present invention is to provide a conduit portion 5 on the end plate 4 of the pump A, one end of which communicates with the inflow starting end 2' of the discharge port 2, and to provide a conduit portion 5 inside the conduit portion 5 by closing the cock. A bypass valve 6 is provided which opens when the internal pressure of the pump increases and returns the liquid to the tank.
尚、上記バイパス弁６は導管内に設けた図示せざる弁孔
を開閉するボール６、このボールを押圧するバネ６“、
バネ止めσ″とで構成される。The bypass valve 6 includes a ball 6 that opens and closes a valve hole (not shown) provided in the conduit, a spring 6'' that presses the ball,
It consists of a spring stopper σ''.
本考案は上述のように構成したので、バイパス弁をタン
クに直結的に連通してもよし、又ホースを接続してもよ
い訳であるが、何れにせよバイパス弁がギャポη°それ
自体に設けられているので例えばホースを接続した場合
でもこのホースに液圧力がかＳることかなくなり、従っ
てホースの外れを適確に防ぐと共に止金具などは一切不
要とすることができるなど実用上の効果は大きい。Since the present invention is configured as described above, the bypass valve may be connected directly to the tank or may be connected to a hose, but in any case, the bypass valve is connected to the gap itself. For example, even if a hose is connected, there is no possibility of fluid pressure being applied to the hose.This prevents the hose from coming off properly and eliminates the need for any fasteners. The effect is great.
