Abstract
A diaphragm circulator for liquid material including a body defining a plurality of propulsion chambers with rigid walls and including a plurality of deformable diaphragms with the chambers being connected in series. In each chamber, between the rigid walls of the chamber, is placed one of the diaphragms with an edge adjacent to an inlet port of the chamber and an edge adjacent to an outlet port of the chamber. A diaphragm-exciting member is arranged to cooperate with the diaphragms in order to generate ripples along the diaphragms. In each diaphragm, at least when the diaphragm ripples, a tension is generated in the diaphragm so that the diaphragm tension on the side of the discharge orifice is greater than on the side of the intake orifice.
