Abstract

Hubraumvariabler Verdichter, insbesondere Axialkobenverdichter, mit mindestens einem Kolben, wobei der Kolbenhub wesentlich durch die Drücke an beiden Seiten des Kolbens bestimmt und der Druck in der Triebwerkskammer durch wenigstens ein Regelventil (2, 7) beeinflußbar ist, wobei das wenigstens eine Regelventil (2, 7) unter Berücksichtigung eines hinterlegten Algorithmus ansteuerbar ist, derart, daß unter Einbeziehung mindestens eines Betriebsparameters (1, 4, 8) der Kolbenhub im wesentlichen in Echtzeit regelbar ist.Displacement variable compressor, in particular Axialkobenverdichter, with at least one piston, wherein the piston stroke essentially determined by the pressures on both sides of the piston and the pressure in the engine chamber by at least one control valve (2, 7) can be influenced, wherein the at least one control valve (2, 7) can be controlled taking into account a stored algorithm, such that, taking into account at least one operating parameter (1, 4, 8), the piston stroke can be regulated essentially in real time.
