Claims (1)
またはダイヤフラム等の可動弁を設け、この可動
弁の往復動で液体を吸入し、吐出するエア駆動形
ポンプであつて、 上記ポンプのエア回路に、液漏れを検出する液
漏れ検出器を設け、 この液漏れ検出器の検出信号に基づいてポンプ
の駆動を停止するポンプ停止手段を設けた エア駆動形ポンプ。[Scope of Claim for Utility Model Registration] An air-driven pump that has a movable valve such as a bellows or diaphragm driven by air back pressure inside the cylinder, and sucks in and discharges liquid by the reciprocating motion of this movable valve. An air-driven pump, wherein the air circuit of the pump is provided with a liquid leakage detector for detecting liquid leakage, and a pump stop means is provided for stopping driving of the pump based on a detection signal from the liquid leakage detector.
