 EMI2.1 
 durch Herabgehen des im oberen Teile vollen Ventilschaftes geschlossen wird. 



   In Fig. 3 ist eine weitere Ausführungsform dargestellt. Hier liegt der Hebel 6 in einer Aussparung 17 des auf einem Keilwiderlager 16 gleitenden   Zwischenstückes   12. Das mit seiner Aussparung 17 als Widerlager dienende   Zwischenstück   12 wird beim Niedergehen des Hebel 6, wie aus der gestrichelten Lage ersichtlich, nach auswärts geführt. Hebel 6 kommt in der tiefsten Stellung des Ventils 2 mit der Aussparung 17 des Zwischenstückes 12 völlig ausser Eingriff, und es kann dann ein unfreiwilliges Öffnen des Ventils nicht mehr erfolgen. Das Öffnen wird erst wieder möglich, wenn der Hebel in seine oberste Lage   zurückgebracht   ist. 



   PATENT-ANSPRÜCHE : 
1. Spritzgussmaschine mit Sicherheitseinrichtung gegen unbeabsichtigtes Öffnen des   Druckluft-   ventils, dadurch gekennzeichnet, dass der Betätigungshebel für das Druckluftventil durch eine Freiauslösung mit diesem verbunden ist.

 EMI2.1
 is closed by descending the valve stem, which is full in the upper part.



   Another embodiment is shown in FIG. Here the lever 6 lies in a recess 17 of the intermediate piece 12 sliding on a wedge abutment 16. The intermediate piece 12, which serves as an abutment with its recess 17, is guided outward when the lever 6 goes down, as can be seen from the dashed position. In the lowest position of the valve 2, the lever 6 comes completely out of engagement with the recess 17 of the intermediate piece 12, and an involuntary opening of the valve can then no longer take place. Opening is only possible again when the lever is returned to its uppermost position.



   PATENT CLAIMS:
1. Injection molding machine with safety device against unintentional opening of the compressed air valve, characterized in that the actuating lever for the compressed air valve is connected to it by a release mechanism.
