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.

Abstract: The invention relates to a valve (10) comprising a casing (11, 12) and an actuator (15). The valve comprises a center element (21, 38) placed parallel with or in extension of a longitudinal extension of the valve, and a closing element (18, 20, 35) being placed along or in extension of the longitudinal extension of the center tube (21). The closing element is movable along the longitudinal extension of the valve and in relation to the center element between a first position, where the closing element closes one or more orifices (24, 39), 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, to a stationary element for a valve and to a vapor compression system, preferably a refrigeration system, being provided with the valve.

Abstract: A linear actuator (1) comprising a first part (3) and a second part (5) is disclosed. The first part (3) is arranged to rotate along with a rotating part (4) of a motor (2), and the second part (5) is arranged to drive an actuated part (18, 22). A coupling (6) interconnects the first part (3) and the second part (5) to allow the second part (5) to rotate along with the first part (3) at the same angular velocity as the first part (3). The coupling (6) defines a fit tolerance between the first part (3) and the second part (5) allowing the first part (3) to rotate a predefined distance before engaging the second part (5) and rotating the second part (5) along with the first part (3). The fit tolerance ensures that the first part (3) reaches a certain angular velocity and thereby that the resulting torque transfer from the first part (3) to the second part (5) is sufficient, e.g. to release the actuated part (18, 22) from a pre-tensioned state.

Abstract: 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).
