  • Refrigerant system having controlled variable speed drive for compressor
    Patent number: 5048302
    Abstract: A refrigeration system includes a compressor, a motor, variable pitch pulleys mounted on the ends of the compressor and motor shafts, and an endless belt looped around the motor and compressor pulleys for drivingly connecting the motor to the compressor. A sensor determines a variance in a refrigerant characteristic of the system from a predetermined value. An electrically powered actuator is responsive to the sensor and effects axial movement to one pulley component of the motor for thereby changing the pitch diameter of the motor pulley and to in turn vary the pitch diameter of the pulley on the compressor so as to change the speed of rotation of the compressor.
