Abstract

　この発明はエア駆動型油圧ポンプに関し、パイロット吸気弁が急速開弁する際の応答性に優れる油圧ポンプを提供することを目的とする。 エア駆動型油圧ポンプは、プランジャーポンプ機構（１０）と、このポンプ機構を駆動するエアシリンダ（２０）と、エアシリンダのエア作動室（２３）に加圧エアを供給する供給状態と加圧エアを排出する排出状態とにわたって自動的に切換わるエア給排切換え機構（３０）とを有する。エア給排切換え機構は、可動弁体（３５）を給気位置と排出位置とにわたって切換えるパイロット給気弁（４１）とパイロット排気弁（４２）とを有し、ポンプ機構のプランジャー（１５）と一体のガイド軸（３８）と、このガイド軸に摺動可能に外嵌装着されたキャップ部材（３９）と、可動弁体とでパイロット給気弁を構成し、ピストンが前進限界位置近傍になったときに、キャップ部材をガイド軸に対して設定距離（Ｇ）相対移動させ、パイロット給気弁を急速開弁させる。
