Abstract:
A pump having an undulating diaphragm mounted for undulating between two end plates under drive from at least one electromagnetic actuator in order to transfer a fluid between an inlet of the pump and an outlet of the pump. The pump includes adapter means connecting the diaphragm support to a movable portion of the actuator in order to shorten the stroke of the movable mass of the actuator such that its stroke is shorter than the stroke of the diaphragm support.
