Therefore, even if resin is used for the valve housing or joint, there is no risk of loosening due to vibration or the like, and airtightness can be maintained. Since the present invention is such a connection mechanism, it is possible to use a resin instead of a metal for one or both of the valve housing and the joint, thereby reducing weight and cost.

Abstract
Description
一方、バルブと継手は、軽量化とコストダウンのために、金属ではなく樹脂で製作することが望まれている。しかし、樹脂は金属と比べてクリープ特性が悪く、長期にわたって気密性能を維持するのが困難である。
また、一般産業用には、継手部分に樹脂材料を用いる場合もあるが、この樹脂材料にはポリブチレンテレフタレート(PBT)を用いているため、剛性、耐熱性、耐薬品性などの面でトラック等の車両に使用されるエア配管用のバルブに適用するのは困難である。
本発明の他の課題は、継手がエルボ形状であっても、スイベル構造を適用しなくても、継手を任意の方向に回転させることができるバルブと継手の接続機構を提供することである。
本発明の他の接続機構は、エア配管におけるバルブのハウジングに継手を介してチューブを接続するための機構であって、前記バルブのハウジングおよび継手の少なくとも一方が樹脂からなり、前記バルブのハウジングには、前記継手を挿入・接続するための接続孔が形成されており、前記継手のハウジング内への挿入状態で、ハウジングの前面に継手抜け止め用のプレート材を取り付け、前記継手に係止させたことを特徴とする。
また、ハウジング外面から挿入するピン等の係止材に代えて、ハウジングの前面に継手抜け止め用のプレート材を取り付けて継手に係止させる構造であっても、上記と同様の効果がある。
さらに、本発明の上記接続機構であれば、エルボ形状の継手であっても、スイベル構造を適用しなくても、配管を任意の方向に回転させることができる。
図1に示すように、本発明の第1の実施形態に係る接続機構は、継手1と、バルブのハウジング2とを接続する機構である。継手1およびバルブのハウジング2は、少なくとも一方が樹脂からなる。使用可能な樹脂としては、例えばポリフタルアミド(PPA)、ポリヘキサメチレンテレフタルアミド(PA6T)、ポリノナメチレンテレフタルアミド(PA9T)、ポリデカメチレンテレフタルアミド(PA10T)、ポリウンデカメチレンテレフタルアミド(PA11T)、ポリメタキシリレンアジパミド(PAMXD6)、ポリフェニレンサルファイド(PPS)、シンジオタクチックポリスチレン(SPS)、ポリカプロアミド(PA6)、ポリヘキサメチレンアジパミド(PA66)、ポリウンデカンアミド(PA11)、ポリドデカンアミド(PA12)等の耐熱性の高い樹脂が挙げられる。使用可能な金属としては、例えばアルミニウム、鉄、銅等が挙げられる。
このとき、継手1は、中心軸Aの周りを回転可能であるが、Oリング4によって確実にシールされていると共に、ピン5によってハウジング2からの抜けが防止されており、かつ従来のねじ止めのような振動による緩みのおそれもない。
なお、継手1’はエルボ形状である以外は、継手1と同じである。
図5は、本発明の第2の実施形態を示している。この実施形態では、継手100がバルブのハウジング200から離脱するのを防止するために、前記したピン5の代わりにプレート材51を使用している。ハウジング200には、継手100を挿入・接続するための接続孔221が形成されている。
