Refrigerant Circuit: RESTRICTOR

WARNING: This page is about a different car, the 2011 Volkswagen CC, 2010 Volkswagen CC, and 2009 Volkswagen CC. However, it is still accessible from the selected car via links, so may be relevant.

The restrictor creates a constriction. This restriction reduces the flow and creates high and low pressure sides in the refrigerant circuit. Before the restrictor the refrigerant which is under a higher pressure is warm. After the restrictor the refrigerant which is under a low pressure is cold. Before the restriction there is a strainer for contaminants and after the restriction there is a strainer, to atomize the refrigerant before it reaches the evaporator.
