Compressors :

1) Rotary Vane - Panasonic

Rotary vane compressors consist of a rotor with three or four vanes and a carefully shaped

rotor housing. As the compressor shaft rotates, the vanes and housing form chambers.

The R134a is drawn through the suction port into these chambers, which become smaller as

the rotor turns. The discharge port is located at the point where the gas is fully compressed.

The vanes are sealed against the rotor housing by centrifugal force and lubricating oil. The

oil sump and oil pump are located on the discharge side, so that the high pressure forces oil

through the oil pump and then onto the base of the vanes keeping them sealed against the

rotor housing.

During idle an occasional vane noise from the compressor may be heard. This is due to the

time taken for lubricating oil to circulate through the A/C system.

2)Scroll type - Sanden

This compressor uses a unique design with two scrolls, one fixed and one is movable, both are inter-leaved.

The movable spiral is able to ORBIT or oscillate without actually fully rotating. The movable scroll is connected

to the input shaft via a concentric bearing.

As the movable spiral oscillates within the fixed spiral, a number of pockets are formed between the spiral. As

these pockets decrease in size the refrigerant is squeezed, the pressure increases and is discharged

through a reed valve at the discharge port in the rear section of the compressor.

3)Variable stroke - Harrison V5

The Delphi (Harrison) V5 compressor is a non-cycling variable displacement compressor.

The compressor varies displacement to control capacity to meet A/C system demand at all operating conditions. The compressor features a variable angle wobble plate in five (V5) cylinder axial piston design.

Displacement is controlled by a bellows actuated control valve located in the rear cylinder head. This control valve senses and responds to the system suction pressure or A/C system demand.

Through regulation of compressor crankcase pressure, the wobble plate angle, and therefore compressor displacement is variable.

In general, the compressor discharge pressure is much greater than the compressor crankcase. Which is greater than or equal to the compressor suction pressure.

At maximum displacement, compressor crankcase pressure is equal to the compressor suction pressure.

At reduced or minimum displacement, the compressor crankcase pressure is greater than the suction pressure.

Technical Information

What you need to know

If you’re replacing an A/C Compressor, you have to be prepared to replace additional components in the system depending on the reason why your own

compressor failed. The information provided below was made to help you save TIME and MONEY.

1.) Compressor locked/seized internally:

If your compressor seized internally it was due to insufficient refrigerant or oil in the system or the system was

blocked, leading to overheating of the compressor which caused a breakdown of internal parts.

Visible symptoms:

The oil in the compressor is black and/or has aluminum particles in it. The belt snapped or when the a/c is

turned on, the engine feels like it’s going to turn off.

What you should do:

1. Replace the A/C Compressor (make sure to add PAG Oil)

2. Replace the Receiver Drier/Accumulator

3. Replace the Expansion Valve/Orifice tube

4. Flushing the a/c lines, condenser and evaporator is REQUIRED (We professionally recommend to replace

the condenser on modern vehicles since the passage on the fins are so small that a flush will not remove all

contaminants).

5. Vacuum the system for 30 – 45 minutes. This will remove any moisture in the system.

6. Add the correct amount of refrigerant to the system.

7. Run vehicle on lowest fan setting for about 3 minutes to allow the compressor to cycle the refrigerant and oil.

The reason why it’s important to replace the additional parts listed is because if you add a

new compressor to acontaminated system, the compressor will cycle the contaminants and will eventually lock up again
