Abstract

Die pneumatische Steuereinrichtung für einen Balgzylinder (10) weist für dessen Betätigung verschiedene Steuerventile auf, von denen zwei Gruppen (28, 31 bzw. 36, 39) dazu dienen, ein Mehrwegeventil (18) zu schalten, das den Zustrom von Druckluft zum Balgzylinder steuert bzw. dessen Entlastung bewerkstelligt. Beim Entlasten des Balg­ zylinders wird ein Ejektor (14) wirksam, durch welchen von der Druckmittelguelle strömendes Druckmittel im Ejektor (14) einen Unterdruck erzeugt, durch welchen der Balgzylinder (10) entleert wird. Auf diese Weise erhält man eine verhältnismäßig einfache und zweckmäßige pneumatische Steuereinrichtung für die rasche Betätigung des Balgzylinders.
