A/C Compressor

Design
A/C compressor 10PA20


Purpose
The A/C compressor (A9) is responsible for sucking in and compressing the refrigerant.


Function
After the electromagnetic clutch (A9k1) has connected the vehicle engine with the A/C compressor, the drive shaft (1) drives the swash plate (3). The swash plate (3) is set at an angle so that the pistons (4) move back and forth as it rotates. During the intake stroke, gaseous refrigerant is sucked in through the suction valve (6).

When the piston (4) moves in the opposite direction, it pumps the gaseous refrigerant through the pressure valve (7), whereby it is compressed and heated up and then flows through the refrigerant line to the condenser.
