With the Bohrungsdurcbmessc.r ^ rüf device for clic lower bore 2 of the spring socket 1, the transducer is via the lever system. 32 is pushed from bottom to top through the gap disc 33 into the bore. Here, the transducer 31 is designed so that a two-point measurement can be made, in which not the flow resistance of the bore itself, but the flow resistance of the gap between the bore wall and the face of the

Leßdüsen transducer arises, is measured.

If the drilling is faulty, the "Aeropan" measuring device a signal is triggered, which via the time relay and the control line 36 a similar ejector device, like in Pig. 7 controls. The cam disc 33 is here again coupled to the anti-drive motor 38 (Pig. 8) for the turntable 15.

In the case of the 'tester for the tightness of the federal P the Pederpfanne 1 becomes the spring-actuated! 39 via the lever system 4o, 41 and the cam disk 42 from above onto the sealing surface of the collar pressed «This creates a seal between the collar and the face of the Iueßwertgebers. The transducer is designed in such a way that, in the event of a leak, there is a loss of pressure in the Keßkammer of the "Aeropan ^ -Measuring device 43 arises, which a signal is stored in the time relay 44 and with this via the control line 45 an ejector device 46 controls, similar to what it does in Pig. 7 is shown. ·

The drive dea turntable 15 takes place via the Drive pulley 52, on the underside of the circumference Rollers 53 are rotatably mounted about vertical axes 54. The lobes are in engagement with the spiral winding ITut 54 of the worm 56 set in rotation by the drive motor 55.

The nozzle (Fig. 9) has the task of, when flowing through * a corresponding liquid to generate the desired spray cone. To do that, you have to the nozzle opening diameter D ö have a certain dimension. If this is not the case, the desired one kicks in Spray cone does not appear, which has a negative impact on the later intended use. The diameter H is also important for the completion. The nozzle is docked in the printer and should sit firmly in it. If the diameter II is too small, the spray bottle will be used the nozzle pushed out and the intended use is not achieved.

The testing of the diameter G was omitted because it is less important for the function plays.

The nozzles are the turntable 15 over, one known vibratory conveyor supplied. You receive thereby a certain situation, so that it is with its great

The one from the transducer exiting air flow is used to record the measured value by the "Aeropan" measuring device 69, in such a way that a greater pressure builds up in the measuring chamber of the "Aeröpan" when in the Nozzle 57 has no bore or the bore diameter is too small. If the bore diameter is too large, the back pressure in the ikeßkammer will be less. If this occurs, the timing relay 63 is activated via the "Aeropan ^ measuring device 62" and the "control line 64 actuates the sorting device Fig. 12. -

The actuating magnet 61 is switched via the contacts 65 by the cam 66 when the cam is set in rotation by the drive motor 55 of the turntable 15.

In the test device for the diameter H, the position of the nozzle 57 on the turntable 15 is determined by means of of the fixing pin 67, which in the nozzle shaft bore 62 immersed, fixed. The readings donor
