Abstract

Die vorliegende Erfindung betrifft eine Vorrichtung zur Be- und/oder Entlüftung einer Mehrzahl von pneumatischen Aktuatoren.The present invention relates to a device for loading and / or venting a plurality of pneumatic actuators.

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.According to the invention, this device 100 has at least one common loading and / or venting chamber 110, in particular a channel-shaped loading and / or venting chamber, wherein this venting / venting chamber 110 is provided with at least one inlet port 120 for each actuator and at least one outlet port 130 and at least one group 200 of air pressure damping formations 210, 220, 230, these formations 210, 220, 230 being offset from each other both in the main air flow direction 400 and perpendicular to the main air flow direction 400 so that this group 200 of formations 210, 220, 230 in the main air flow direction 400 projects a gapless wall 300.

Die erfindungsgemäße Vorrichtung weist sehr gute Schalldämpfungseigenschaft auf und lässt sich kostengünstig und mit geringem Aufwand herzustellen.
