  • Positive displacement micropump
    Patent number: 5338164
    Abstract: This invention is for a pump having a series of chambers in a stack wherein electrodeformable material is used to deform a diaphragm to change the volume in the chambers. The architecture of the pump features stacks of chambers having a common diaphragm between adjacent chambers such that when a diaphragm is deformed to increase the volume in one chamber it simultaneously decreases the volume in the adjoining chamber. In one embodiment the stacks of chambers can be combined with other stacks to increase the head pressure in stages. In a second embodiment the stages can be in the same stack.
