摘要： A pneumatically controlled valve unit is specified, having a main valve for controlling a fluid flow of a fluid to be dosed. The valve unit has a piston shiftably mounted in a valve chamber, operating against a return device, and connected to a valve closing body of the main valve to open and close the main valve. The piston delimits a pressure chamber within the valve chamber such that the piston can be shifted against the return device by pressurizing the pressure chamber, wherein a position sensor is provided which is set up to detect the position of the piston in the valve chamber. One respective pressure line leads from the pressure chamber to a pressure fluid port and a ventilation port, wherein an aeration valve is arranged in one pressure line and a ventilation valve is arranged in the further pressure line, and wherein a control unit is provided which is set up to switch the aeration valve and the ventilation valve on the basis of the position of the piston detected by the position sensor to regulate a pressure in the pressure chamber for shifting the piston. Furthermore, a valve system comprising at least one valve unit, and a method of operating the valve unit are specified.

摘要： A solenoid fluid control valve for controlling fluid flow. The solenoid fluid control valve may comprise a transceiver that receives a signal via a controller area network (CAN) bus, and a micro controller unit that decodes the signal to determine a temperature. The micro controller unit may send a signal to a driver circuit based on the temperature. The driver circuit may send a current through a coil in response to the signal, wherein an armature moves in response to the current through the coil. The movement of the armature may direct a cooling fluid flow.

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.
