Abstract (en)

[origin: EP1843040A2] Method involves accomplishment of pressure compensation between the individual pump chambers (1,2), during the pre-compressions phase and prevention of pressure compensation between the individual pump chambers, during the subsequent conveying stroke. The two pump chambers are provided for each liquid and movable displacement body (4,5). One of the displacement bodies absorbs liquid during the actual conveying phase of the other displacement body. An independent claim is included for the oscillating positive-displacement pump.
