Sloherity gas connection

The present invention represents a further improvement of patent 1,136,294 with the aim of ensuring reliable and easy coupling even when extreme tolerances are encountered intervene in the chick and thus cause reciprocal take-away. The plug 2 according to patent 1,136,294 therefore has two recesses 38 instead of the previous actuating hooks 4, into which two correspondingly fixed pins 39 that are worked on the ball cage engage. If now the recesses of the rotating and fastening stub 22 grip these pins 39 firmly connected to the ball cage 5 and take them with them, the actuating cams 4 with the balls 6 in the ball cage 5 inevitably also go with «The balls 6 can therefore always be safely in the bores 24 enter the turning and fastening socket 22, whereby the coupling process is secured.

In the accompanying drawing, the invention is shown in an exemplary embodiment, namely shows

ELg. 1 a cut through the safety gas tap accordingly

Fig. 1 of the patent 1,136,294, Fig. 2 shows a section duroh the plug part according to Fig. 4 and of patent 1,136,294,

Fig. 3 is a section through the chick ^, from which the recess 38 is to be seen,

Mg, 4 a section rotated by 90 ° compared to the section after Fig. 3 »with the two opposing recesses 38 are recognizable,

Fig. 5 shows a vertical section through the ball cage 5 with the holes 40,

! • ig. 6 shows a section along Mnie X-X of FIG. 5, so that one can see from these two FIGS. 5 and 6, the two pins 39 clearly can see which in the recesses 38 of the chick intervention*

The ■ device works as follows:

The hose connector 21 with the rotating and fastening connector is inserted into the opening of the gas inlet cock (Fig. 1), that the recesses 23 of the rotating and fastening stub 22 partially grip over the pin 39 of the ball cage 5, wherein at the same time the bores 24 of the rotating and fastening stub 22 come to rest over the balls β * By turning of the rotating and fastening connector 22 to the left take the Recesses 23 over the pin 39, the ball cage 5 and the Chick 2 so that the balls 6 out of the ball grooves 12 and into the bores 24 of the rotating and fastening connector 22 be pressed. By this engagement of the balls 6 in the Bores 24 of the rotating and fastening stub 22 is the same connected, .Hose connector 21 and thus the. Hose held tight and by further turning the turning and fastening connector 22 to the left, the chick 2 is gebraohi in the manner described above in the open position. By turning each other, i.e. after right, the GrasduajQhgang is closed again and only in
