Expansion valve: evaporator feed control

Useful to know

The expansion valve regulates the supply of refrigerant to the evaporator in systems that use such a valve. HELLA describes this function separately from the compressor and other parts of the climate contour. [1]

On a schematic, he traced the agent's path first, then the air route to the compartment. These are related but different processes. Do not determine the type or setting of the valve by a randomly similar photo. Working on the refrigeration circuit requires the specific data and equipment; the general principle does not give a universal correction procedure.
