"MEMBRANE PUMP" characterized by being driven by a fast motor, with speed reduction incorporated in the base, and with a vertical eccentric shaft; two helical wheels move the plate that carries, in a groove, the eccentric stump support of the connecting rod; this rod moves in a horizontal plane and transmits its oscillation directly to an elastic membrane, causing the volume between it and the plate to increase or decrease alternately.
