Zusammenfassung:To provide a pump that imparts low shear force and turbulence to a fluid being pumped.SOLUTION: A reciprocating positive-displacement pump comprises: a hemispherical rigid chamber wall; a flexible membrane attached to the rigid chamber wall so that the flexible membrane and rigid chamber wall define a pumping chamber; an inlet for directing the flow through the rigid chamber wall into the pumping chamber in a direction that is substantially tangential to the rigid chamber wall; and an outlet for directing the flow through the rigid chamber wall out of the pumping chamber in a direction that is substantially tangential to the rigid chamber wall.SELECTED DRAWING: Figure 3 【課題】圧送されている流体に低せん断力および乱流を付与するポンプを提供すること。【解決手段】往復容積式ポンプは、半球状である堅固なチャンバ壁と、可撓膜および堅固なチャンバ壁が圧送チャンバを規定するように堅固なチャンバ壁に取り付けられた可撓膜と、堅固なチャンバ壁を通過して圧送チャンバへ流入する流れを堅固なチャンバ壁に対して実質的に接線方向に方向づける入口と、堅固なチャンバ壁を通過して圧送チャンバから流出する流れを堅固なチャンバ壁に対して実質的に接線方向に方向づける出口とを備える。【選択図】図3
