摘要：
A method of producing a flow of a fluid through a passage (24) defined in a rigid frame (22) comprises selectively actuating a flexible membrane (38) disposed across a midpoint of the passage (24) with an actuating system in a manner which produces a wave-like motion in the membrane (38) thereby causing a peristaltic movement of the fluid through the passage (24).
