    Abstract: Electric expansion valve (1) including a valve housing (12), a valve seat (2), a valve element (3) cooperating with the valve seat (2), a drive driving the valve element (3) and including a rotary motor (4) having an axis (17) of rotation. The valve element (3) is connected to the motor (4) and has a possibility of radial displacement between the rotor (6) and the valve element (3) with respect to the axis (17) of rotation. Such an expansion valve should ensure a long lifetime with low production costs. To this end the valve element (3) is connected to the motor (4) by means of a fixing element (16) which guarantees a defined position of the valve element (3) in axial direction while allowing the radial displacement between the axis (17) of rotation and the valve element (3).

    Abstract: A method for attaching an object, such as a sight glass (3) or an electrical connector (4), to a structure, such as a valve housing (1), the object (3, 4) comprising an annular flange (6, 11). The object (3, 4) is mounted in an opening (7, 12) of the structure (1) with the annular flange (6, 11) in abutment with an annular edge (8, 13) of the opening (7, 12). The object (3, 4) is attached to the structure (1) by performing welding of the annular edge (8, 13) and the annular flange (6, 11) and displacing the welding beam along the annular flange (6, 11).

    Abstract: A valve (1) comprising a first housing part (2) and a second housing part (3), the first housing part (2) and the second housing part (3) being made from a sheet metal material, and being joined by means of welding, preferably laser welding, to form a closed housing of the valve (1). An actuator (9) is arranged inside the housing for driving movements of a first valve member (7) and/or a second valve member (8), said actuator (9) being arranged directly in a flow of fluid flowing in the fluid flow path during operation of the valve (1). The valve (1) is hermetically sealed due to the welding of the housing parts (2, 3).

    Abstract: The invention relates to an axial valve comprising an actuator (15) and a center tube (19). The actuator comprises a stationary element (16) and a closing element (17), and the center tube (19) is placed axially in relation to an axial extension of the stationary element (16). The center tube (19) is in a fixed position relative to the stationary element (16). Fluid, such as refrigerant, is intended for flowing through the valve and through the center tube. The center tube (19) comprises orifices (22) for fluid passage. The closing element (17) is placed axially to an axial extension of the center tube (19) and is movable axially along the center tube between a first position, where the closing element closes the orifices (22) of the center tube, thereby not allowing fluid to pass the orifices, and a second position, where the orifices (22) are open, thereby allowing fluid to pass the orifices.
