PNEUMATIC AND PNEUMATIC CIRCUITS

Abstract— Pneumatic circuits are used to generate, transmitand transform forces and movements by means of compressedair.A pneumatic circuit is composed of the following elements:

1. The compressed air source, which is the device thatcompresses the air in the atmosphere until it reaches therequired pressure to run the installation.

2. Pipes and ducts, through which circulates the water orthe ouse

!. Actuators, such as cylinders and motors, which are incharge of the tubes become pistons and move them totrigger the circuit.

". #ontrol elements, such as the distribution valves. Thevalves open or close the passage of air.

$. %lectrical screws serving for the doors of the means of transport

Index Terms ircuits, pneumatic
