  • Compressor modulation system with multi-way valve
    Patent number: 11879460
    Abstract: A compressor may include first and second scrolls, an axial biasing chamber, and a control valve. The second scroll includes an outer port and an inner port. The outer and inner ports may be open to respective intermediate-pressure compression pockets. The control valve may be in fluid communication with the inner port, the outer port, and the axial biasing chamber. Movement of the control valve into the first position allows fluid communication between the inner port and the axial biasing chamber. Movement of the control valve into the second position allows fluid communication between the outer port and the axial biasing chamber.
    Type: Grant

  • Compressor modulation system with multi-way valve
    Patent number: 11655813
    Abstract: A compressor may include first and second scrolls, an axial biasing chamber, and a modulation control valve. The second scroll includes an outer port and an inner port. The outer and inner ports may be open to respective intermediate-pressure compression pockets. The modulation control valve may be in fluid communication with the inner port, the outer port, and the axial biasing chamber. Movement of the modulation control valve into a first position switches the compressor into a reduced-capacity mode and allows fluid communication between the inner port and the axial biasing chamber while preventing fluid communication between the outer port and the axial biasing chamber. Movement of the modulation control valve into a second position switches the compressor into a full-capacity mode and allows fluid communication between the outer port and the axial biasing chamber while preventing fluid communication between the inner port and the axial biasing chamber.
