PRECISE CONTROL OF SUCTION DAMPING DEVICE IN A VARIABLE DISPLACEMENT COMPRESSOR
20200224647 · 2020-07-16 ·

A suction damping device for a variable displacement compressor includes a rotor rotatably received within a stator disposed in a suction port of the variable displacement compressor. The rotor includes an aperture and the stator includes a pair of opposing openings in selective fluid communication with the aperture of the rotor. An electromagnetic device controls a rotational position of the rotor relative to the stator based on a condition of an electrically controlled valve used to control an angle of inclination of a swashplate of the variable displacement compressor. A changing of the rotational position of the rotor relative to the stator causes a variable overlap to be formed between the aperture of the rotor and the openings of the stator to control a flow of a refrigerant through the suction damping device.
