The fixed
displacement compressors compress refrigerant
in accordance with the engine rotation.
Denso provides three types of fixed
displacement compressors– swash plate type, scroll type and vane
type.
In the swash plate
fixed displacement compressor, a swash plate, fixed to the shaft,
rotates to reciprocate pistons, and the reciprocating pistons
compress refrigerant.

Technology
In 1997, Denso
introduced a swash plate fixed displacement compressor that applied a
newly developed two-layer surface treatment coat to a swash plate,
significantly improving the swash plate abrasion resistance while
maintaining its sliding capability, resulting in longer life.
In 2003, Denso used
new materials for the two-layer surface treatment coat of
the swash
plate, further improving its abrasion resistance even with a small
amount of lubricant.
Benefits and
Features
High durability
The two-layer
surface treatment coat for the swash plate gives the compressor high
durability.
Small size and light weight
Gaskets and M6
bolts are used to hermetically seal the compressor,
reducing the
compressor diameter.
Low noise, vibration and high compressor efficiency
A unique structure to
tightly fix the swash plate to the housing, reducing
the noise and
vibration caused by the swash plate rotation, while allowing the swash
plate to smoothly and stably rotate. The smooth, stable rotation of
the swash plate results in high compressor efficiency.
