WHAT ARE THE BASIC ELEMENTS OF A PNEUMATIC SYSTEM?

By Admin on


A – Compressor:

a pump which compresses air, raising it to a higher pressure, and delivers it to the pneumatic system (sometimes, can also be used to generate a vacuum).

 B – Check valve:

one-way valve that allows pressurized air to enter the pneumatic system, but prevents backflow (and loss of pressure) into the compressor when it is stopped.

 C – Accumulator:

stores compressed air, preventing surges in pressure and relieving the duty cycle of the compressor.

 D – Directional valve:

controls the flow of pressurized air from the source to the selected port. Some valves permit free exhaust from the port not selected. These valves can be actuated either manually or electrically (the valves typically provided in the FIRST kits use dual solenoids to change the direction of the valve, based on input signals from the control system).

 E – Actuator:

converts energy stored in the compressed air into mechanical motion. A linear piston is shown. Alternate tools include rotary actuators, air tools, expanding bladders, etc.
