Working principle of piston air compressor

Piston air compressor compresses gas through the reciprocating motion of the piston in the cylinder. When the piston moves to the right, the pressure in the left chamber of the piston in the cylinder is lower than the atmospheric pressure, the suction valve opens, and the outside air is sucked into the cylinder; when the pressure in the cylinder is higher than the pressure in the output air pipe, the exhaust valve opens. The reciprocating motion of the piston is formed by the crank slider mechanism driven by the motor, and the rotational motion of the crank is converted into sliding - the reciprocating motion of the piston.
