AUTOMATIC AIR CONDITIONING SYSTEM

MECHANISM AND FUNCTION

4. Air Conditioning System

1 . COMPRESSOR

A wobble plate type electronically controlled variable deliv-

ery compressor is used . The solenoid actuator built in the

compressor is controlled by the auto control unit . This

ensures optimum compressor delivery with less power and

less fuel, as well as smooth driving feel since compressor

ON-OFF is eliminated .

In addition, the quick cool-down capability and defrosting

capability during low temperatures are improved as well .

2) Mechanism

Five cylinders and pistons are axially arranged around the

drive shaft with equal separation of 72°. These pistons per-

form the suction, compression and discharge strokes.

The piston operating in the cylinder is driven by a wobble

plate, hence this construction is called the wobble plate

type . The compressor delivery is changed by changing the

piston stroke, and the piston stroke is changed by chang-

ing the inclination angle of the wobble plate.
