1-Product description - Swash plate system
Valeo TM08 , TM13 , TM15 & TM16 are 6 cylinder
swash plate type compressors. With this type of
compressor, the cylinders and pistons are arranged
axially along the drive shaft.
The pistons operate within the cylinders and
are driven by a swash plate to perform suction,
compression and discharge.
Swash plate system
The drive shaft, which is driven by the engine
through the magnetic clutch, is equipped with a
swash plate.
The drive shaft is supported by two radial bearings
and two thrust bearings.
The swash plate is rotated by the drive shaft, and
moves the pistons back and forth.
Piston Drive System
The pistons in the cylinders are mounted on the
swash plate through hemispherical shoes.
Each piston has a compression head at each end. The
rotation of the swash plate results in a reciprocating
piston movement horizontal to the drive shaft.
The cylinders, which are arranged at 120° intervals
around the drive shaft, are each divided into 2
chambers providing 3 front and 3 rear bores.
As each piston performs suction and compression at
either end, the compressor operates as a 6 cylinder
compressor.
