SCROLL SCS08 COMPRESSOR
The compressor used on this vehicle is the scroll type and is equipped with a system w h i c h deactivates it
when the evaporator reaches temperatures where freezing may take place.
The compressor consists of a fixed scroll (1) which has a casing and an orbital scroll (2); the movement
of the t w o scrolls, w h i c h takes place through the camshaft (3) connected to the pulley, produces a
chamber in which the volume decreases during rotation allowing compression.
The adoption of this compressor, consisting of only t w o moving parts, has resulted in the f o l l o w i n g ad­
vantages:
- no seals are required;
- there are no leaks, either radial or axial;
- low load losses through the absence of internal valves and pipes;
- the wear of the spirals produces an improved seal of the side panels of the actual spirals;
- the absence of valves, knocking and impulses reduces noise levels.
