Abstract
The micromembrane pump has a pump membrane (110). This is moved by a drive device (100) into a first and a second position. The pump also has a pump body (102) connected to the pump membrane to define a pump chamber (112) between them. The pump has an inlet opening with an inlet valve (106), and an outlet opening with an outlet valve (108). When the membrane moves from the first to the second position, it increases the volume of the pump chamber by a stroke volume. When the membrane moves from the second to the first position, it decreases the volume of the pump chamber by a stroke volume. The ratio of the stroke volume to the volume of the pump chamber, when the pump membrane is in the first position, satisfies a given inequality based on the atmospheric pressure, the adiabatic coefficient and the maximum pressure, dependent on the valve geometry and the valve load, which is necessary to open the valve. ADVANTAGE - Allows pumping of compressible medium. Has automatic priming behaviour and is tolerant to bubbles.
