    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: 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: 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 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.
