The oil drain plug must be removed and the oil drained through the plug opening to insure
complete draining of oil from the compressor.
4) V-5 Compressor-Operation
The V5 is a variable displacement compressor that can match the automotive air conditioning
demand under all conditions without cycling. The basic compressor mechanism is a variable
angle wobble-plate with seven axially oriented cylinders. The center of the control of the
compressor displacement is a billows-actuated control valve located in the rear head of the
compressor that senses compressor suction pressure. The wobble-plate angle and the
compressor displacement are controlled by the crankcase suction pressure differential. When
the A/C capacity demand is high, the suction pressure will be above the control point. The valve
will maintain a bleed from crankcase to suction. With no crankcase suction pressure differential,
the compressor will have maximum displacement.
When the A/C capacity demand is lower and the suction pressure reaches the control point, the
valve will bleed discharge gas in the crankcase and close off a passage from the crankcase to
suction plenum. The angle of the wobble-plate is controlled by a force balance of seven pistons.
A slight elevation of the crankcase suction pressure differential creates total force on the piston
resulting in a movement about the wobble-plate pivot pin that reduces the plate angle. The
compressor has a unique lubrication system. The crankcase suction bleed is routed through the
rotating wobble-plate for lubrication of wobble-plate bearing. The rotation acts as an oil
separator that removes some of the oil from the crankcase where it can lubricate the
compressor mechanism.
5) Condenser Core
The condenser assembly in front of the radiator consists of coils, which carry the refrigerant and
cooling fins that provide the rapid transfer of heat. The air passing through the condenser cools
the high-pressure refrigerant vapor and causes it to condense it to condense into a liquid.
6) Receiver-Drier
The sealed receiver-drier assembly is connected between the condenser and evaporator. It
acts as a refrigerant storing container, receiving liquid and some vapor and refrigerant oil from
the condenser. At the bottom of the receiver-drier is the desiccant, which acts as drying agent
for the moisture that may have entered the system. An oil bleed hole is located near the bottom
of the receiver-drier outlet pipe to provide an oil return path to the compressor. The receiver
drier is serviceable as an assembly.
