Abstract

Die vorliegende Erfindung betrifft eine Vorrichtung zur Be- und/oder Entlüftung einer Mehrzahl von pneumatischen Aktuatoren.
Erfindungsgemäß weist diese Vorrichtung 100 zumindest eine gemeinsame Be-und/oder Entlüftungskammer 110, insbesondere eine kanalförmige Be- und/oder Entlüftungskammer, auf, wobei diese Be-/Entlüftungskammer 110 mit zumindest einem Einlassanschluss 120 für je einen Aktuator und zumindest einem Auslassanschluss 130 versehen ist und zumindest eine Gruppe 200 von Luftdruck dämpfenden Ausformungen 210, 220, 230 aufweist, wobei diese Ausformungen 210, 220, 230 voneinander sowohl in der Lufthauptströmungsrichtung 400 als auch senkrecht zur Lufthäuptströmungsrichtung 400 so versetzt angeordnet sind, dass diese Gruppe 200 von Ausformungen 210, 220, 230 in der Lufthauptströmungsrichtung 400 projektiert eine lückenlose Wandung 300 darstelit.
Die erfindungsgemäße Vorrichtung weist sehr gute Schalldämpfungseigenschaft auf und lässt sich kostengünstig und mit geringem Aufwand herzustellen.
