Claims (3)

弁本体と蓋部材とにより反転板の周辺部が挟持され、
前記弁本体には、前記反転板の一方の面に弾接する支持バネの収容室と、流体の流出通路とが備わっており、
前記蓋部材には、前記反転板の他方の面上に載置される弁体を移動自在に収容する弁室と、前記弁体により開閉される弁座と、前記弁室に連通する流体の流入通路とが備わっており、
前記反転板は、閉弁状態では前記弁体を前記弁座に向けて付勢する方向の力を発生するとともに、開弁状態では前記支持バネをそのバネ力に抗して圧縮する方向に力を発生するように形成され、
前記流入通路側から前記弁体に作用する力が前記反転板と前記支持バネの力の合計の力より大きくなったときに開弁し、前記流入通路側から前記弁体に作用する力が前記反転板と圧縮状態の前記支持バネの力の合計の力より小さくなったときに閉弁する
ことを特徴とする逆止弁。 The periphery of the reversing plate is sandwiched between the valve body and the lid member,
The valve body includes a support spring accommodating chamber that elastically contacts one surface of the reversing plate, and a fluid outflow passage,
The lid member includes a valve chamber that movably accommodates a valve body placed on the other surface of the reversing plate, a valve seat that is opened and closed by the valve body, and a fluid that communicates with the valve chamber. With an inflow passage,
The reversing plate generates a force in a direction for urging the valve body toward the valve seat in the valve-closed state, and a force in a direction for compressing the support spring against the spring force in the valve-open state. Formed to generate
When the force acting on the valve element from the inflow passage side becomes larger than the total force of the reversing plate and the support spring, the force acting on the valve element from the inflow passage side is The valve is closed when the total force of the reversing plate and the support spring in the compressed state becomes smaller than the total force.
A check valve characterized by that . 開弁状態における前記支持バネが圧縮されたときのバネの力は、前記反転板が前記支持バネを圧縮する力よりも大きくなるように設定されていることを特徴とする請求項１記載の逆止弁。 The reverse force according to claim 1 , wherein the force of the spring when the support spring is compressed in the valve open state is set to be larger than the force with which the reversing plate compresses the support spring. Stop valve. 前記支持バネは円錐バネであることを特徴とする請求項１記載の逆止弁。 The check valve according to claim 1, wherein the support spring is a conical spring .
