  • Capacity modulated scroll compressor
    Patent number: 9022759
    Abstract: A compressor including a housing defining a suction pressure region and a discharge pressure region includes first and second scroll members forming compression pockets. A first chamber located on the first end plate of the first scroll member includes first and second passages and a first aperture extending therethrough and in communication with the first chamber. The first aperture provides communication between a compression pocket and the first chamber. A modulation assembly is located in the first chamber and includes a heater and a thermal valve. The valve is displaceable from a first position that isolates the first passage from the second passage and a second position that permits communication between the first and second passages. The valve is displaced as a result of a temperature change provided by the heater.
