(FR) DISPOSITIF ET PROCÉDÉ DE RÉDUCTION ACTIVE DE FLUCTUATIONS DE PRESSION DANS UN SYSTÈME HYDRODYNAMIQUE
Abstract
(DE) Die Erfindung betrifft eine Vorrichtung zur aktiven Reduktion von Druckfluktuationen in einem hydrodynamischen System mit einer Pumpe, einem Druckfluktuationsgenerator und mindestens einem Drucksensor sowie einer Reglereinheit. Die Reglereinheit ist dazu eingerichtet, den Druckfluktuationsgenerator zu steuern und ein Druckfluktuationssignal von dem Drucksensor zu empfangen. Weiterhin betrifft die vorliegende Erfindung ein korrespondierendes Verfahren sowie einen Druckfluktuationsgenerator für eine entsprechende Vorrichtung.
(EN) The invention relates to a device for actively reducing pressure variations in a hydrodynamic system, comprising a pump, a pressure variation generator, at least one pressure sensor and a control unit. The control unit is configured to control the pressure variation generator and receive a pressure variation signal from the pressure sensor. The invention further relates to a corresponding method and a pressure variation generator for a corresponding device.
(FR) L'invention concerne un dispositif de réduction active de fluctuations de pression dans un système hydrodynamique comprenant une pompe, un générateur de fluctuations de pression et au moins un capteur de pression ainsi qu'une unité de régulation. L'unité de régulation est conçue pour commander le générateur de fluctuations de pression et pour recevoir un signal de fluctuations de pression du capteur de pression. En outre, la présente invention concerne un procédé correspondant ainsi qu'un générateur de fluctuations de pression pour un dispositif correspondant.
