Ein Großteil der in der Physik verwendeten
Formeln ist auf den im englischen verwendeten
Begriff zurückzuführen. So auch in der
Pneumatik.Die Formel des Drucks p F / A hieße
im englisch ausformuliertpressure is equal to
force per area (Druck ist gleich Kraft pro
Fläche)

• Druck p pressure
• Kraft F force
• Fläche A area
• Arbeit W work
• Leistung P power
• Zeit t time

• In der Pneumatik gibt es verschiedene
  Betätigungsarten um Ventile anzusteuern.
• mechanisch
• pneumatisch/ elektrisch
• per Muskelkraft

• In the pneumatics there are several
  possibilities to operate valves.
• mechanical
• pneumatic/ electric
• by muscle-power

• The cylinders 1A1 and 2A1 are retracted in the
  initial position. In the initial position, 1A1
  switches the limit switch 1S1, while 2A1 switches
  the limit switch 2S1. Pressure is applied to the
  air supply line II. Pressure is present at a
  single port of each of the two dual-pressure
  valves 0V3 and 0V4. The dual-pressure valve 1V2
  is switched.

11
After operating the pushbutton 1S3
12
pressure is present at both ports of 0V4.
13
0V4 switches throught,
14
0V3 switches throught and switches 0V1 at port
14.
15
By that, pressure is taken from supply line II
and supply line I becomes filled with pressure.
The dual-pressure valves 0V5 and 2V2 become, each
at a single port, supplied with pressure.
16
1V1 becomes switched at port 14,
17
1A1 extends,
18
actuates 1S2
19

• which causes the valve 2V2 to switch throught.

20
2V1 becomes actuated at port 12
21
which causes 2A1 to extend.
22
2S2 becomes switched
23
and switches 0V5 throught which actuates 0V1 at
port 12.
24
Pressure is taken again from supply line I and
supply line II becomes filled with pressure
25
which actuates 2V1 at port 12.
26
2A1 retracts
27

• and actuates 2S1.

28
The dual-pressure valve 1V2 becomes supplied with
pressure by supply line II and 2S1
29
switsches throught and actuates 1V1 at port 12.
30

• 1A1 retracts.
