Compressors
•
The Tribute is equipped with a swash-plate compressor with fixed displacement, while
the Mazda3 Diesel and the Mazda2 use variable displacement compressors. The main
difference between both compressor types is that the variable displacement compressor
does not cycle on and off during normal operation.
Variable Displacement Swash Plate Compressor
•
The variable displacement swash plate compressor functions similar to the standard
swash plate compressor described earlier. The two major differences are the variable
swash plate and the control valve. The control valve controls the pressure on the rear
side of the pistons based on the low and high pressure. The pressure difference
between the front and the rear side of the pistons determines the angular position of the
variable swash plate and hence the piston stroke. The benefit of this is that the
compressor does not cycle on and off under normal operation.
