Abstract: 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.

Abstract: A method for creating a maximum capacity variance of an expansion valve (1) is described, the expansion valve (1) comprising a valve housing (2) having a valve seat (4) at an end of a valve seat channel (5) and a valve element (3, 3a, 3b, 3c). It should be possible to show a simple and cost-effective way to provide expansion valves having different maximum flow capacities. To this end, the variance is created by using a valve element (3, 3a, 3b, 3c) having a capacity controlling part (7, 7a, 7b, 7c) and a flow controlling part (6, 6a, 6b, 6c), wherein different capacity controlling parts (7, 7a, 7b, 7c) are used to create the maximum capacity variance.

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).

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 pretensioned state.
