Abstract: 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.

Abstract: The invention relates to a valve (10) comprising a casing (11,12) and an actuator (15). The valve comprises a center tube (21) placed parallel in relation to the longitudinal extension of the valve, and a closing element (18) being placed along the extension of the center tube, and said closing element at least partly extending along a sidewall of the center tube. The closing element is movable along the longitudinal extension of the valve and in relation to the center tube between a first position, where the closing element closes the one or more orifices (24), thereby not allowing fluid to pass the orifices, and a second position, where the one or more orifices are open, thus allowing fluid to pass the orifices. The invention also relates to a method of assembling the valve and to a vapor compression system, preferably a refrigeration system.

Abstract: A mechanism is described for determining whether or not a ground connection is properly earthed by determining whether or not a potential difference exists between a voltage measuring point and a ground connection. A first capacitor is connected between the ground connection and a first power line and a first duplicating capacitor (having the same capacitance as the first capacitor) is connected between the voltage measuring point and the first power line. If the determining step determines that the potential difference does not exist, then it is determined that the ground connection is not properly earthed.
