GMC Topkick A/C Expansion Device Parts

GMC Topkick A/C Expansion Device

The AC expansion device is used to allow the flow of refrigerant according to the cooling needs in your GMC car. So when we increase the cooling effect in the car, the expansion valve enlarges to release large amount of refrigerant getting into the air conditioning unit. In the same way, when we decrease the cooling effect, the evaporator valve will shrink and release lesser amount of air getting into the air conditioning unit. The expansion valve contains three pressure points which regulates the amount of refrigerant entering the air conditioning unit. The three points of pressure which regulates the amount of refrigerant entering the AC unit are bulb, evaporator and spring.

The evaporator valve and the spring act together to close the value when we reduce the level of cooling and the same process implies when we increase the cooling, the bulb opens the valve using its pressure.
