Describe the main operating features of any one of the following: Air compressor Strip heater Three-jaw chuck. - Leaving Cert Engineering - Question i - 2021

The air compressor operates using an electric motor that drives a compressor unit. Air is drawn into a cylinder, where it is compressed by a piston. As the compressor functions, it builds up pressure within the storage tank. When the desired pressure level is reached, the electric motor stops, thereby halting the compressor's operation.

The storage tank serves to store the compressed air and maintain a steady supply. Once the pressure within the tank decreases to a certain level, the electric motor is activated again to restore the pressure. This cycle continues, ensuring that the air compressor can deliver a constant supply of compressed air as needed.
