WSM KX080-3 Mechanism
C.Main components
a. Compressor
The compressor is installed on the engine and is driven by crank pulley through a belt.
The compressor is a pump designed to raise the pressure of refrigerant. Raising the pressure means
raising the temperature. High temperature refrigerant vapor will condense rapidly in the condenser by
releasing heat to the surrounding.
Compressors are classified as follows:
Reciprocationg type
Rotary type

(1) Outline of sliding-vane type compressor (SV07 type) :

This compressor consists of the following main parts: rotor with built-in five vanes and cylinder, two dis-
charge valves, side plates on the front and back. As the rotor turns, the five vanes also turn pressed into
contact with the inner surface of the cylinder by the centrifugal force and the back pressure of the vanes
themselves.

(2) Feature
1) The rotor, cylinder and other major parts are made of aluminum for tremendous drop in weight.
2) The vanes are used to make the compressor compact.
3) Compared to conventional swash-plate compressors, the SV07 is compact with smaller cylinder
capacity. Thanks to the better volumetric efficiency, however, the SV07 proves as powerful as the
10P08.
