ABSTRACT:
A micromembrane pump is described which is self-priming and self-filling. For this, the pump chamber (14) is so configured that in a drained condition of the pump chamber (14), the pump membrane (4) adjoins the pump chamber wall (22), which causes the volume of the pump chamber (14) to be minimized. For this, the pump chamber wall (22) can be flat, so that the pump membrane (4) adjoins the flat pump chamber wall (22) in its unshifted rest position. Preferably, the pump includes membrane valves which consist of a valve membrane (3) situated between two halves of the housing (1, 2), and valve seats (10, 16). It also includes a heteromorphic piezoactuator (5) attached to the pump membrane (4). The compact pump is suited to deliver gases and liquids, and can be manufactured in cost-effective fashion from only a few components.
