Continuously Variable Capacity Compressor
When the shaft rotates, the slope plate rotates by means of the lug plate which is attached to the shaft. The rotational movement of the slope plate is converted through the use of shoes to the reciprocal movement of the pistons, which in turn take in, compress, and discharge the refrigerant.
The inner pressure of the slope plate chamber is controlled between low to mid range, and the pressure determines the slope angle, determining the piston stroke as well and further controlling the discharge amount, resulting in the continuously variable capacity.
The amperage to the variable capacity control solenoid valve is controlled to obtain continuously variable low pressure, further achieving the continuous control of variable compressor capacity resulting in the continuous control of the cooling capacity.
On/Off of the compressor clutch is eliminated in the system, hence no shock of the clutch engaging/disengaging, and the idle speed becomes stable.
