Title (EN) METHOD OF OPERATING A FLUID WORKING MACHINE
(FR) PROCÉDÉ DE FONCTIONNEMENT D'UNE MACHINE À FLUIDE
Abstract: front page image
(EN)When the fluid flow output of a synthetically commutated hydraulic pump is adapted to a given fluid flow demand, pulsations in the fluid output flow of the synthetically commutated hydraulic pump can occur. To avoid such pressure pulsations, it is suggested, to use a set of pre- calculated actuation patterns for actuating the electrically commutated valves of the synthetically commutated hydraulic pump.
(FR)Lorsque le débit de sortie du fluide d'une pompe hydraulique à commutation synthétique est adapté à une demande d'écoulement de fluide donné, il peut y avoir des pulsations dans le débit du fluide de la pompe hydraulique à commutation synthétique. Pour éviter ces pulsations de pression, il est suggéré d'utiliser un ensemble de schémas d'actionnement précalculés pour actionner les soupapes à commutation électrique de la pompe hydraulique à commutation synthétique.
