WSM KX080-3 Mechanism
(4) Structure Function
The basic internal construction of sliding-vane type compressor consists of a rotor fitted with five vanes,
and a cylinder.
Although its internal construction partially differs from that of the through-vane type compressor, the
function is identical. Its basic operation is to effect the suction, the compression, and the discharge of
refrigerant gas by rotating the rotor, pushing the vanes to the cylinder inner wall, and allowing the vanes
to rotate while sliding along the cylinder wall.
Similar to the through-vane type compressor, the sliding-vane type compressor uses the ND-OIL8 for the
compressor oil.

ylin er Internal onstruction
Internally, the cylinder consists of a rotor fitted with five vanes. These vanes slide in contact with the
inner cylinder wall to effect the suction, the compression, and the discharge of refrigerant gas.
2) Shaft
The shaft is integrated with the rotor. The front of the shaft is supported by the needle bearing which
is fitted in the front side plate. The rear is supported by plain bearing which is fitted in the rear side
bearing.
The end of the shaft is provided with splines, and the magnetic clutch (K type) that mates to the
spline shaft is secured by a bolt (M6), in the same way as in the through-vane type compressor.

The rear side plate is equipped with a valve that prevents the vanes from chattering during starting.
