(1) Pressure Relief Valve
If the high pressure is abnormally high, the pressure
relief valve (1) opens to protect the circuit.
Even in the worst case, the outflow of refrigerant is
stopped at the minimum limit.
(Reference)
• In normal operation, the high pressure switch is
triggered first and the compressor stops, so the
pressure relief valve is not triggered so easily.

(2) Magnetic Clutch
A magnetic clutch is used to engage and disengage
the compressor from the engine. Main components are
stator (6), rotor with pulley (5), and pressure plate (1) to
engage the drive pulley (4) and compressor (8)
magnetically.
The stator is fixed on the compressor housing, and
the pressure plate (1) is attached to the compressor
shaft. Two ball bearings (2) are used between the inner
surface of the rotor and the front housing of the
compressor.
