1 Service Training TT The compressor

2 Service Training VSQ/TT 2/14 Contents The refrigerant compressor Internally controlled compressor Magnetic coupling Externally regulated compressor Overload protection

3 Service Training VSQ/TT 3/14 The refrigerant compressor Swash plate compressor with electromagnetic coupling Video "Initial operation" F208_027

4 Service Training VSQ/TT 4/14 Drive With electromagnetic coupling Internally controlled compressor F208_047

5 Service Training VSQ/TT 5/14 Low pressure High pressure Guide rail Swash plate Regulating valve Drive shaft Chamber pressure Springs Drive hub Upper side Piston Lower side Calibrated restrictor hole Overview Internally controlled compressor F208_047

6 Service Training VSQ/TT 6/14 Low pressure Bellows 2 Chamber pressure High pressure Spring 2 Restrictor hole Chamber pressure Spring 1 Regulating valve Bellows 1 Swash plate adjustment increases Internally controlled compressor F208_048

7 Service Training VSQ/TT 7/14 Low pressure Bellows 2 Chamber pressure High pressure Spring 2 Restrictor hole Chamber pressure Spring 1 Bellows 1 Regulating valve Swash plate adjustment decreases Internally controlled compressor F208_049

8 Service Training VSQ/TT 8/14 Solenoid coil Diagram showing coupling switched on Spring plate with hub Flow of power Belt pulley with bearing Compressor drive shaft Compressor housing Diagram showing coupling switched off Overview Magnetic coupling F208_003F208_002

9 Service Training VSQ/TT 9/14 Overview Externally regulated compressor Belt pulley with rubber moulding – overload protection Compressor regulator valve N280

10 Service Training VSQ/TT 10/14 Suction pressure High pressure Swash plate Hollow piston Control valve N280 Drive shaft Return spring Crankcase High pressure side Suction side Crankcase pressure Compression chamber Maximum delivery of swash plate Externally regulated compressor F240_012

11 Service Training VSQ/TT 11/14 Zero delivery of swash plate F240_011 Externally regulated compressor

12 Service Training VSQ/TT 12/14 ACrankcase pressure BHigh pressure CLow pressure Direction of full load – A to B separated Direction of no load – A to B opened C restricts control valve depending on low pressure. Externally regulated compressor 2 – Mechanical components 1 – Electromagnetic components Compressor regulator valve N280
