To intentionally create a restriction, an orifice (auth uses the term expansion valve which is incorrect in this scenario).
Liquid refrigerant flow is restricted when it flows through the orifice. This causes the pressure to drop which causes the refrigerant to flash/boil. While the refrigerant is flashing/boiling, it is absorbing heat from the surrounding environment.
