Title (EN) METHOD OF OPERATING A FLUID WORKING MACHINE
(FR) PROCÉDÉ DE FONCTIONNEMENT D'UNE MACHINE À FLUIDE
Abstract: front page image
(EN)To improve the fluid output flow characteristics (14) of a synthetically commutated hydraulic pump (1), it is suggested to use a plurality of different valve (10) actuation strategies. For every fluid flow demand region (I to Vl) a certain actuation strategy is chosen.
(FR)Pour améliorer les caractéristiques d'évacuation du fluide (14) d'une pompe hydraulique à commutation synthétique (1), il est proposé d'utiliser plusieurs stratégies d'actionnement des différentes soupapes (10). Pour chaque région de demande d'écoulement de fluide (I à VI), on choisit une certaine stratégie d'actionnement.
