2Ein 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)
3Beispiele (examples)
- Druck p pressure
- Kraft F force
- Fläche A area
- Arbeit W work
- Leistung P power
- Zeit t time
- Rauminhalt V volume
4Pneumatic components
- Druckluftanschluss - connection with
compressed air - einfach wirkender Zylinder -single acting
cylinder -
- doppelt wirkender Zylinder -twofold acting
cylinder - 2/2-Wege-Ventil -2/2-way valve
- 3/2-Wege-Ventil -3/2-way valve

7- 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
8- A pneumatic circuit
- Ein pneumatischer Schaltkreis

10- 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.
11After operating the pushbutton 1S3
12pressure is present at both ports of 0V4.
130V4 switches throught,
140V3 switches throught and switches 0V1 at port
14.
15By 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.
161V1 becomes switched at port 14,
171A1 extends,
18actuates 1S2
19- which causes the valve 2V2 to switch throught.
202V1 becomes actuated at port 12
21which causes 2A1 to extend.
222S2 becomes switched
23and switches 0V5 throught which actuates 0V1 at
port 12.
24Pressure is taken again from supply line I and
supply line II becomes filled with pressure
25which actuates 2V1 at port 12.
262A1 retracts
27 28The dual-pressure valve 1V2 becomes supplied with
pressure by supply line II and 2S1
29switsches throught and actuates 1V1 at port 12.
