Types of Compressor and Structure: Swash Plate Type (Fixed Displacement)


This pistons is constructed from the components shown in the illustration.
The pistons move back and forth when power from the engine causes the shaft and swash plate to rotate.
One piston is comprised of cylinders on both sides. The ends of the piston intake pressurize and discharge refrigerant.


In the cylinder shown in the right of the illustration, the suction valve is opened when the piston moves to the left. The pressure difference between the suction shaft within the housing and inside the cylinder causes refrigerant to enter the cylinder through the suction valve. Conversely, when the piston moves to the right, the suction valve is closed and the refrigerant is pressurized. Continued pressurization increases the pressure of the refrigerant in the cylinder, causing the discharge valve to open. The refrigerant then flows to a high-pressure pipe.
(The suction and discharge valves prevent flow back of the refrigerant.)
The balance of characteristics and reliability in this compressor make it suitable in a wide-range of vehicles around the world, such as small vehicles, mini-vans, large busses, and construction equipment.
