で一体成形し、該弁体を戻しばねの付勢力にて常
時バルブ本体の弁座に当接させ、前記バルブ本体
のインレツトポートから流出する流体の圧力によ
つてのみ前記弁体を開放するようにした逆止弁に
おいて、前記弁体の外周面に径方向へ延びる周溝
を形成すると共に、該周溝の最深部を前記弁体と
前記弁座との当接位置より軸心側に配置したこと
を特徴とする逆止弁。 The valve body housed in the valve chamber of the valve body is integrally molded with an elastic material, and the valve body is always brought into contact with the valve seat of the valve body by the biasing force of a return spring, and the valve body flows out from the inlet port of the valve body. In the check valve, the valve body is opened only by the pressure of the fluid, in which a circumferential groove extending in the radial direction is formed on the outer peripheral surface of the valve body, and the deepest part of the circumferential groove is connected to the valve body. A check valve characterized in that the check valve is disposed closer to the shaft center than the contact position between the check valve and the valve seat.
