1 - PRODUCT DESCRIPTION - SWASH PLATE SYSTEM
Valeo TMX is a 10 cylinders swash plate type compressors. 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.
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 parallel to the drive
shaft. The cylinders, which are arranged at 72°
intervals around the drive shaft, are each divided
into 2 chambers providing 5 front and 5 rear bores.
As each piston performs suction and compression
at either end, the compressor operates as a 10
cylinder compressor.
