Franky,
You don't need or really want a seal.
Seems that it's a bush ...which is needed.

English links ..but should give you the idea.

19mm I.D
14mm Widthso 47mm O.D.

"But i think, although its mathematically there is a mistake in some datas, the wasching-maschine didn´t flew 2m "
Perhaps.
Try here.

metric
Flipper tip force ...lets average it from 600kg to around 60kg at fully open.
so 330 kg average tip force ?
Flipper tip travel.. shut to open ? ...700 mm?
load 100 kg
Peak height of launched load (meters ) = ?
BTW ..What IS your cylinder bore and stroke...I guessed at 50mm bore and 130mm stroke.

Franky,
Hopefully you'll understand English ..if not perhaps Leo or someone will translate.
Ive sent you a spreadsheet by email..using dimensions scaled from your pics.
The mathmatical throw of 100kg with 2 Burkerts and 2 off two litre buffers.
is 2.43 metres above the floor
With only one buffer ...saving weight..2.32 metres
With one buffer and one burkert ...using the other on the rams exhaust to shut the flipper arm quicker...2.26 metres
Real life may well be different.Cheers Woody
EDIT :- Calculations above @ 58 Bar = temp of 20 Celsius
Temperature on your test day 10 Celsius ?
If so the 1st flip pressure would be @ 45 Bar and would reduce further with every flip.CO2 liquid turns to gas by extracting heat from itself and it's surroundings so the bottle gets colder as the gas is used .

You'll need large external contactors / relays to obtain Forward and Reverse on a P.M. Motor.

Well that's a new one on me!
You learn something new everyday.

All the coils I know of have open ends.... the thing that varies is the bore / hole size.

No Leo,
The setup is correct.

Looks good to me.

You could consider this option.

S.E.V ...Schnellentlueftungsventil is I think the correct term for a Quick Exhaust Valve.

Small mistake Mario ... 1/2" B.S.P. is 14 T.P.I.
As Mario said about the size designation of B.S.P.
B ritish S tandard P ipe
The size refers to the BORE of our standard pipe or tube that the thread is cut on.

Another pic ...

The pic is supposed to show a co2 bottle ....then a PRESSURE REGULATOR ... followed by the magnet valve.
The gas pressure is reduced by the regulator .....passes through the 3/2 valve and into the pressure chamber via the Quick Exhaust Valve ( essentially a one way valve that blocks the gas return ).
Firing the 3/2 valve removes feed pressure and causes the flap in the QEV to move back blocking the entrance port and uncovering the BIG exit port into the barrel...... the pressure chamber then dumps it's contents QUICKLY into the barrel.
I hope that makes sense.

Good grief Leo ...you'll be putting the ball into orbit!
If your suggesting using the 5404 at full pressure.An adaptation of the antenna launcher is going to be fairly easy.
Remove the trigger .
Then add in the CO2 Bottle ,regulator and 3/2 valve.... plus a small battery..... then adjust the pressure to get the required velocity.

"Das Ventil hat hat ja ein konisches Gewinde, welches sich zum Ende hin verjüngt"
I think you'll find that the thread is M25 x 2mm and parallel.
Core of the valve thread approx 23mm ...... outside diameter of 1/2" BSP = 21mm
So very close ...
Thinnest part = 1mm
Thickest part = 3mm -

"So da ich zur Zeit ein wenig Urlaub habe, habe ich wieder mal ein bisschen mein Pneumatik System gewidmet und gleich schon wieder die nächste Frage auf dem Bild sieht man den Anschluss zu meinen Puffertank, da dieser am Ausgang kein 1/2" Gewinde hat sondern ein paar zehntel mehr und schon völlig verkorkst ist, dachte ich mir das ding einfach an der Roten Linie ab zu Schneiden und innen dann einfach aufbohren und 1/2" rein zu Schneiden, was meint ihr ist das machbar ?
Cut off the valve thread ....drill and tap with your choice of thread.
