ABSTRACT
The energy chain is composed of a large number of essential components, including pneumatic components that ensure the generic functions of the operating part. The pneumatic system is powered via a filter, a regulator and a lubricator. The compressed air is distributed, whilst the actuator converts the pneumatic power into mechanical power. This article details the various technologies for the design of this distribution system, as well as the characteristics and criteria of choice of its components. To conclude, various accessories (for the control of cylinders for instance) as well as the various types of connections are examined.
Read this article from a comprehensive knowledge base, updated and supplemented with articles reviewed by scientific committees.

INTRODUCTION
Pneumatic components are essential constituents of the energy chain. They perform the generic functions of the operating part: powering, distributing, regulating, converting and transmitting.
The
The pneumatic distribution network, via filter, regulator and lubricator, feeds the pneumatic circuit of the industrial automation system. The distributor distributes this compressed air on command from the information chain. Circuit accessories (flow reducer, non-return valve, etc.) are used to adjust the actuator. The actuator converts pneumatic power into mechanical power. Couplings and mechanisms associated with the actuator transmit force and speed, thus acting on the workpiece.
In this dossier, we detail the different construction technologies, characteristics and selection criteria for these pneumatic components. We then examine the various types of connection and linkage between these components.
