摘要： 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.

摘要： Electric expansion valve (1) comprising 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 comprising 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).

摘要： 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.
