When the stator is energized, a magnetic field is created, causing the rotor to start rotating. The rotary motion of the rotor is transmitted through an axis to the piston. At the head of the piston there is a plate that has two vanes (blades) which, together with the piston, will suction and compress the refrigerant as follows:
1- When the piston is in the low part, the suction vane opens admitting the refrigerant refrigerant of the evaporator;
2- When the piston is in the up position, the suction vane closes to prevent coolant flow back into the evaporator and the compression vane opens by flushing the coolant into the condenser.
Every mechanical assembly of the compressor is suspended by three springs, giving the compressor very low noise levels during its operation.
