    Abstract: A solenoid valve (1) is described comprising a first port (2), a second port (3), a valve element (4) and a valve seat (5) arranged between said first port (2) and said second port (3), a coil (12) and a yoke arrangement (14-16), said coil (12) being magnetically linked to said yoke arrangement (14-16), said yoke arrangement (14-16) having a movable armature (16). In such a solenoid valve the generation of noise should be kept low. To this end said valve element (4) is driven by a pressure difference between a first pressure on a first side (6) of said valve element (4) and a second pressure on a second side (7) of said valve element (4), at least one of said first pressure and said second pressure being controlled by means of said armature (16), wherein said armature (16) comprises a first front face (18) at a first end and a second front face (19) at a second end opposite said first end, said first front face (18) and said second front face (19) being connected by a first flow path (21), said first flow path having first throttling means for keeping low a flow of a fluid flowing through said first flow path (21).

    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.

The latter is displaceable along the axial direction (A). The check valve unit (1, 100, 200, 300, 400) further includes a valve head (25, 125) with a sealing surface (33, 133), wherein the valve head (25, 125) is disposed on a distal end (21) of the valve shaft (20, 120) in the axial direction (A), the distal end (21) facing away from the mounting portion (11). Further, a damping reservoir (50) is provided inside the shaft bearing body (10, 110, 210, 310, 410). A volume of the damping reservoir (50) is changed by axial movement of the valve shaft (20, 120). In order to obtain a well-defined times for opening and closing under given conditions and to make the check valve unit (1, 100, 200, 300, 400) less prone to making noise, at least two channels (46a, 46b) are provided in parallel, each of them constituting a fluid connection between the damping reservoir (50) and an outside (70). The damping reservoir (50) is, apart from the channels (46a, 46b), at least substantially enclosed. Each channel (46a, 46b) has a length being at least ten times a hydraulic diameter of the respective channel (46a, 46b).
