13に当っている。A female screw 2 is formed on the inner peripheral surface of the front end portion of the tubular casing 1, and a tubular body 3 having a male screw 4 on the outer periphery is screwed into the female screw 2 and spreads rearward at the rear portion of the tubular body 3. A tapered seat portion 5 is formed. The tubular body 3
A shaft body 9 is provided via a required connecting arm 8 so that the shaft center and the shaft center of the casing 1 coincide with each other, and the shaft body 9 faces the taper seat portion 5 toward the front. A flow rate control valve body 10 having a tapered surface 11 is fitted in such a manner that it can slide back and forth, and the flow rate control valve body 10 is biased rearward by a spring 12 so that, in a normal state, Tsuba
Hitting 13
この状態で、テーパー面11とテーパー座部５との間に間
隔（通路）が形成されるようになっている。In this state, a space (passage) is formed between the tapered surface 11 and the tapered seat portion 5.
前記流量調節弁体10に逆止弁体16が前後摺動自在に嵌め
られ、この逆止弁体16は、これと鍔13とに圧縮状態で当
てられたばね17によって後方に付勢されて、ケーシング
１の後端部に設けられた弁座18に密接するようになされ
ている。A check valve body 16 is fitted to the flow rate control valve body 10 so as to be slidable forward and backward, and the check valve body 16 is biased rearward by a spring 17 pressed against the check valve body 16 and the collar 13 in It is arranged to be in close contact with a valve seat 18 provided at the rear end of the casing 1.
逆止弁体16は、設定長さ前方に移動すると流量調節弁体
10に当接して流量調節弁体10を前方に押すようになされ
ている。When the check valve body 16 moves forward by the set length, the flow control valve body
The flow control valve element 10 is brought into contact with 10 to push the flow rate control valve element 10 forward.
（実施例の作用） 次に実施例装置の作用を説明する。(Operation of Embodiment) Next, an operation of the embodiment apparatus will be described.
ケーシング１の入口６の側の圧力がばね17の力より大き
くなると、逆止弁体16が開いて流体は出口７に至る。When the pressure on the inlet 6 side of the casing 1 becomes greater than the force of the spring 17, the check valve body 16 opens and the fluid reaches the outlet 7.
そして、更に、入口６の側の圧力が大きくなると、逆止
弁体16が更に前方に移動させられて流量調節弁体10に当
接し、それをばね12の力に抗して押すので、流量調節弁
体10は前方に移動する。その結果、テーパー面11がテー
パー座部５に接近して両者間の間隔が狭くなって、流量
が絞られる。Then, when the pressure on the inlet 6 side further increases, the check valve body 16 is moved further forward and abuts the flow rate control valve body 10, and pushes it against the force of the spring 12. The control valve body 10 moves forward. As a result, the taper surface 11 approaches the taper seat portion 5 and the gap between the two is narrowed, so that the flow rate is reduced.
（考案の効果） この考案は、前記した如き構成によって、以下の如き効
果を奏するものである。(Effect of the Invention) The present invention has the following effects due to the above-described configuration.
流量調節弁体と逆止弁体とが筒状のケーシング内に納め
られているので、逆止弁の機能と入口側の圧力が高くな
り過ぎると流量を絞る機能とを有するコンパクトな弁装
置を提供することが出来る。Since the flow rate control valve body and the check valve body are housed in the cylindrical casing, a compact valve device having the function of the check valve and the function of restricting the flow rate when the pressure on the inlet side becomes too high is provided. Can be provided.
