Abstract
【解決手段】ベンチレータ装置に適した往復ポンプは、シリンダ10の中を軸方向に往復でき、その内部を吸入チャンバと排出チャンバとに分割するピストン13と、吸入チャンバの中に固定された壁12と、壁に固定された駆動収納部16とからなっている。駆動収納部は、モータMと、モータによって回転させられる回転子17と、駆動収納部内で回転するナット18と、ナットの一端にねじ込まれ、ピストンの他端に固定されたスクリュー21とからなる。ピストンは実質的に軸方向あるいは回転方向に動けるようになっており、モータによってナットが前後方向に回転させられると、スクリューとピストンはシリンダ内を軸方向に往復運動し、また、シリンダに対しスクリューとピストンが回転して、ピストンとシリンダの間での磨耗を平均化するようにできる。
