🎯Benefits of technology

【0011】 本発明のクイックカプラは、スリーブの連通孔がOリングに交差する向き、好ましくは直交する向きに延びる長孔なので、Oリングを連通孔に引っかけることなく弁体を移動させる。また、本発明のクイックカプラは、スリーブの外周面に凹部を形成していないので、Oリングが凹部で膨らみ、再び圧縮することがなく、弁体も制動を受けない。こうして、本発明のクイックカプラは、圧縮されたOリングによる一定の移動抵抗で弁体が移動するので、ソケットに対するプラグの抜き差しに際して弁体が制動を受けなくなり、弁体を付勢するバネの力を弁体の移動抵抗に対抗できる程度に抑えながらも、プラグをソケットから引き抜く際もバネの力だけで弁体を移動できる。

Abstract

In a quick coupler in which a fluid shut-off mechanism is configured by a valve body that moves along a sleeve containing the plug or socket, and an O-ring holding the valve body moves across a communication hole in the sleeve, the valve body is moved only by the force of a spring. [Solution] In a quick coupler 1 in which a fluid shut-off mechanism is configured by a socket-side valve body 34 that moves along a socket-side sleeve 32 built into the socket 3, and an O-ring 341 for the socket-side sleeve held by the socket-side valve body 34 moves across a socket-side communication hole 322 of the socket-side sleeve 32, the socket-side communication hole 322 is an elongated hole that extends in a direction perpendicular to the O-ring 341 for the socket-side sleeve.
