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.
