摘要： A compressor system includes a first compressor and a second compressor. A common equalization line fluidly couples the first compressor and the second compressor and provides a single path for passage of fluids between the first compressor and the second compressor. An obstruction device is disposed in the common equalization line. Responsive to one of the first compressor and the second compressor being deactivated while the other of the first compressor and the second compressor remains active, the obstruction device is in a closed configuration. When in the closed configuration, the obstruction device prevents flow of fluid between the first compressor and the second compressor. Prevention of fluid flow between the first compressor and the second compressor causes at least minimum prescribed fluid levels to be maintained in the first compressor and the second compressor.

摘要： An electronic expansion valve (1) is provided, comprising an inlet (9), an outlet (8), an armature (2), a stop member (3), a biasing member (4) and a solenoid coil (12). The biasing member (4) provides a biasing force on the armature (2) towards a closing direction while the solenoid coil (12) may be provided with a current to provide a magnetic force on the armature (2) towards an opening direction.
It is intended to provide an electronic expansion valve that may be controlled more precisely and has a higher safety.
To this end the pressure difference between the inlet pressure and the outlet pressure provides a differential pressure force on the armature (2) towards an opening direction to allow a fluid flow from the inlet (9) to the outlet (8), and furthermore the armature (2) is displaced away from the stop member (3) to allow a fluid flow from the inlet (9) to the outlet (8) if the sum of the magnetic force and the differential pressure force on the armature (2) exceeds the biasing force. The invention furthermore relates to a refrigeration system comprising such an electronic expansion valve as well as a method for calibrating such an electronic expansion valve.
