    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: The present invention pertains to an active balancing valve for a refrigeration and/or air-conditioning application. The valve comprises a valve housing (1) with an inlet orifice (11), an outlet orifice (12) and a mounting portion (13), a main valve element with a main pressure balance orifice and a control element at least partially defining a pressure balance passage. Each element is slidable inside the valve housing and comprises a control surface for controlling a fluid flow between the inlet orifice and the outlet orifice. The control element closes the main pressure balance orifice of the main valve element in a closed state of 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 pretensioned state.
