  • Method and device for degassing the transport chamber of a metering pump
    Patent number: 8540799
    Abstract: A method is provided for degassing a transport chamber (1) of a metering pump. The method is based on performing impulse generation, wherein gas bubbles arising from the gas-forming fluid and adhering to the inner surfaces in the transport chamber (1) are released from the surfaces, wherein the gas bubbles (4.4?, 8.8?) present in the transport chamber (1) accumulate, perform a motion (c) in the direction of the pressure valve (6), and form an accumulated gas bubble (7) on the transport chamber side of the pressure valve (6). An increase in pressure causes the accumulated gas bubble present at the pressure valve (6) to escape from the transport chamber (1) as discharged gas bubbles (7?) into the pressure line. A metering pump having a device present in the transport chamber for performing the impulse generation is also provided.
