3.1 HOW THE COMPRESSOR WORKS
3.1.1 COMPONENTS
The basic components of the air compressor are the electric motor, pump, tank and pressure switch. The
motor
(item A) powers the pump. The motor drives a pulley and belt, which transfers power from the motor to
the pump pistons via a flywheel and a crankshaft. The flywheel fan helps cool the pump.
The
pump
(item B) compresses the air and discharges it into the tank. As the piston in the pump cylinder
moves downward, air enters the cylinder through the filter and air intake valves at atmospheric pressure. As
the piston moves upward, it compresses the air and discharges it into the tank through an unloader/check
valve.
The
tank
(item C) stores the compressed air. A check valve at the tank inlet prevents the compressed air in
the tank from flowing back into the pump.
The
pressure switch
(item D) shuts down the motor when the air pressure in the tank reaches the kick-out
pressure. As compressed air is used and the pressure level in the tank drops to the kick-in pressure, the
pressure switch restarts the motor automatically, without warning, and the pump resumes compressing air.
