Abstract

In a rotary compressor for refrigeration and heat pump systems with an integrated drive motor on the high-pressure side, the operating medium will flow over the drive motor. During operating of the rotary compressor gas pulsations/pressure pulses will occur on both low-pressure and high-pressure sides. In order to suppress these pressure pulses on the high-pressure side one or more chambers with different volumes are provided, joined by channels between the discharge opening and the drive motor.
