Abstract

A pump comprising a deformable tube which passes through an external casing divided into air-tight chambers each connected to a source of increased and reduced pressure. The tube contains a valve means so that when different parts of the tube are subjected to a predetermined sequence of variations in pressure by varying the pressure in the chambers fluid within the tube is urged from its inlet to its outlet.
