Description
verbunden, der einen vorspringenden Rand 12 aufweist. Der Ring 7 ist vorteilhaft mehrfach geteilt und greift mit seinem vorspringenden Rand 12 in eine Ringnut 13 in der innenwand 14 des Blaszylinders 4 ein.connected, which has a protruding edge 12. The ring 7 is advantageously divided several times and engages with its protruding edge 12 in an annular groove 13 in the inner wall 14 of the blow cylinder 4 a.
Im dargestellten Ausführungsbeispiel ist der Ring 7 dreifach geteilt, wie aus der Fig. 3 zu entnehmen ist, in der die Ringteile mit la, 7 b, Ic bezeichnet sind. Diese Ringteile sind in eine Randausnehmung 15 des Zylinderbodens 6 eingelegt und durch mit dem Zylinderboden 6 verbundene Schrauben 16 in ihrer Lage fixiert. Dabei sind zwischen den Ringteilen 7 und den Schrauben 16 Haltescheiben 19 zwischengelegt, die mit ihrem Rand die Ringteile 7 a, 7 b, 7 c übergreifen.In the illustrated embodiment, the ring 7 is divided into three parts, as can be seen from FIG. 3, in which the ring parts are designated by la, 7b, Ic . These ring parts are inserted into an edge recess 15 of the cylinder base 6 and fixed in their position by screws 16 connected to the cylinder base 6. In this case, retaining washers 19 are interposed between the ring parts 7 and the screws 16, the edge of which extends over the ring parts 7 a, 7 b, 7 c .
Die Randausnehmung 15 des Zylinderbodens 6 wird durch eine Schulter 20 begrenzt, gegen die sich die Ringteile 7 a, 7 b, 7 c bei der Ausschaltbewegung des Blaszylinders 4 anlegen. Die Schulter 20 überträgt dabei die beim Verdichten des Löschgases in der Blaseinrichtung auftretenden Kräfte.The edge recess 15 of the cylinder base 6 is delimited by a shoulder 20, against which the ring parts 7 a, 7 b, 7 c apply when the blowing cylinder 4 is switched off. The shoulder 20 transmits the forces that occur when the extinguishing gas is compressed in the blowing device.
Wie die F i g. 3 zeigt, ist jeder Ringteil 7a, 7 b, 7 c von zwei Schrauben 16 in seiner Lage fixiert. An Stelle der im Ausführungsbeispiel gezeigten Schrauben können auch Gewindebolzen vorgesehen sein, die mit dem Zylinderboden 6 fest verbunden, insbesondere im Zylinderboden 6 verankert sind.As the F i g. 3 shows, each ring part 7a, 7b, 7c is fixed in its position by two screws 16. Instead of the screws shown in the exemplary embodiment, threaded bolts can also be provided which are firmly connected to the cylinder base 6, in particular anchored in the cylinder base 6.
Durch Anwendung der Erfindung lassen sichBy applying the invention can
xo kompakt aufgebaute Blaseinrichtungen schaffen, die raumsparende Aufbauformen von elektrischen Druckgasschaltern ermöglichen. Die Montage der Blaseinrichtung, insbesondere die Verbindung des Blaszylinders mit dem zugehörigen Antrieb, läßt sich mittels des mehrfach geteilten Ringes leicht vornehmen, so daß die Fertigung des elektrischen Druckgasschalters nach der Erfindung vereinfacht und darüber hinaus Wartungsarbeiten am Schalter mit geringem Aufwand durchführbar sind.xo create compact blowers that enable space-saving designs of electrical pressure gas switches. The assembly of the Blowing device, in particular the connection of the blowing cylinder with the associated drive, can be easily make by means of the multi-split ring, so that the production of the electrical pressure gas switch simplified according to the invention and also maintenance work on the switch with can be carried out with little effort.
