1 Expansion valve

Location
The expansion valve is located in the front module, immediately behind the cooler.

Task
The expansion valve separates the refrigerant circuit's high-pressure area from the low-pressure area.

Function
When the refrigerant compressor (A9) is switched on, the pressure in the evaporator decreases causing a diaphragm in the expansion valve to arch. The diaphragm motion is transferred to a linkage. The linkage presses the valve ball out of its seat opening the valve. The opened valve enables the refrigerant to be sprayed into the evaporator.
