Overpressure valve
   
The overpressure valve is mounted on the compressor or on the liquid tank.
At an approximate pressure of 38 bar, the valve opens and closes again when the pressure decreases (approx. 30 bar).
The refrigerant gas does not flow out completely.
Depending on the model, there may be a transparent plastic washer that breaks when the valve is activated.
