Abstract

急激にケース内の圧力が上昇した場合においても、ケース内部の液体は排出せずに確実に回収し、外部への排気だけを行い、ケース内部の圧力調整を行えるブリーザを提供することを目的とする。 このため、ケース内部の内部圧力が所定圧を超えて高くなると、外部へ排気を行って内部圧力を減圧し、前記ケース内部の内部圧力の調整を行うブリーザであって、前記ケース内部から外部へ通じる排気経路と、前記ケース内部から排出された液体を前記ケース内部に回収させる液体回収経路と、前記ケース内部の内部圧力が所定圧を超えると開弁する排出弁手段とを備えたブリーザにおいて、前記排出弁手段を越えた大気側に前記流体回収通路を設け、この流体回収通路に回収弁手段を設けた。
