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. The pneumatic control device for a bellows cylinder (10) has for the actuation of various control valves, two of which Groups (28, 31 and 36, 39) serve to a multi-way valve (18) switch that controls the inflow of compressed air to the bellows cylinder or its discharge. When relieving the bellows an ejector (14) is effective through which the Pressure fluid source flowing in the ejector (14) one Generated negative pressure through which the bellows cylinder (10) emptied becomes. This way you get a relatively simple and Appropriate pneumatic control device for quick actuation of the bellows cylinder.
