摘要： A Peristaltic micropump includes a first membrane region with a first piezo-actor for actuating the first membrane region, a second membrane region with a second piezo-actor for actuating a second membrane region, and a third membrane region with a third piezo-actor for actuating the third membrane region. A pump body forms, together with the first membrane region, a first valve whose passage opening is open in the non-actuated state of the first membrane region and whose passage opening may be closed by actuating the first membrane region. The pump body forms, together with the second membrane region, a pumping chamber whose volume may be decreased by actuating the second membrane region. The pump body forms, together with the third membrane region, a second valve whose passage opening is open in the non-actuated state of the third membrane region and whose passage opening may be closed by actuating the third membrane region. The first and the second valve are fluidically connected to the pumping chamber.
