ABSTRACT:
The bellows in the stroke control valve of a variable stroke axial piston wobble plate refrigerant compressor is partially filled with an anti-freeze solution and continuously exposed to both suction pressure and crankcase pressure. This has the effect of reducing the piston stroke at high compressor speeds while increasing suction pressure to maintain some air conditioning performance.
