Abstract (en)
[origin: EP1091120A2] The method involves feeding a pumped medium to the pump, which has at least one displacement element on a rotary shaft that pumps the medium into a vol. during a compression process. The position of a pressure extreme in the vol. is determined during the pumping process and a pump operating parameter is determined and/or controlled depending on the time and/or angular positions of the pressure extreme.
