the discharge the discharge pressure suddenly collapses and atomization ends without dripping the patient can now introduce the connecting piece 13 into his second nostril after preparing the discharge device for the second discharge stroke step this takes place in that the actuating sleeve 25 is rotated by approximately 30 u00b0 using the handle 33 knurling a comparison of fig3 and 4 makes it clear that the spokes 29 are under a roughly 30 u00b0 distance from the slots 43 in walls 44 at the end of the first discharge stroke step they struck against the same roughly in the center of the portions 49 they are now turned to such an extent that they are located above the slots 43 the downwardly extended wall portion forms the turning s top 38 if now the actuating sleeve 25 in fig1 is pressed upwards again then the spokes 29 engage on webs 40 on reaching the predetermined actuating pressure for the second discharge stroke step the material webs 41 also break away there the second discharge stroke step is performed in the same way as the first in that the lower terminal edge of the piston rod 16 presses the pist on stopper 21 further into the medium container 20 and therefore delivers the medium in the manner of a thrust piston pump through the discharge channel 19 in the.
