ABSTRACT:
A pump for conveying liquid, especially resonance pump, which comprises an alternating current operable oscillating armature which is supported by a leaf spring, and also comprises an elastically flexible thin-walled plate which is likewise supported by the leaf spring and extends into a pump passage through which liquid is conveyed within the pump. The pump furthermore includes electromagnets adapted when energized to cause the armature alternately to swing to one and the opposite side so that the leaf spring and the plate carry out synchronous movements in a direction transverse to the longitudinal axis of the pump. The plate has a considerably lower bending resistance than the leaf spring.
