Patent ID: 8714944

Claim:
A pump, comprising: an undulating diaphragm; a diaphragm support; two end plates, said undulating diaphragm being mounted on said diaphragm support such that the diaphragm undulates between said 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; and adapter means connecting the diaphragm support to a movable mass of a movable portion of the actuator, said adapter means being adapted to shorten the stroke of the movable mass of the actuator when said movable mass is oscillating and such that the stroke of the movable mass is shorter than the stroke of the diaphragm support and said adapter means comprise a first lever and a second lever each hinged firstly to the diaphragm support and secondly to a respective stationary point, wherein the movable mass of the movable portion of the actuator is coupled to a point of the first lever and to a point of the second lever.
