Types of Compressor and Structure: Scroll Type (Fixed Displacement)
Structure
This compressor is constructed from one fixed and one rotating scroll in an offset spiral configuration.
Shaft rotation creates spaces of varying volume between the 2 scrolls, causing refrigerant to be sucked in and compressed.
Operation
As the rotating scroll moves, the space between the two scrolls also moves, causing the volume of this space to gradually decrease.
Refrigerant flows in from the suction port and is gradually compressed by the rotating scroll rotation. It is discharged from the discharge port after approximately 3 rotations.
Refrigerant is actually discharged once for each rotation.
It is an extremely quiet and efficient compressor used mostly in small and light cars.
