  • Actuator of a refrigerant valve, valve arrangement comprising a refrigerant valve and an actuator and method for mounting an actuator of a refrigerant valve to the refrigerant valve
    Patent number: 11566719
    Abstract: An actuator of a refrigerant valve is described, the actuator comprising a housing (5) having a chamber (12) with an opening (15) in an end face (26) of an end section (17) of the housing (5), the end section (17) having an outer thread (18), a tightening collar (6) having a radially inwardly protruding flange (20) and an inner thread (19) matching the outer thread (18), and an anchor ring (7) positionable between the tightening collar (6) and the end face (16), wherein the anchor ring (7) is elastically deformable at least in a radial direction with respect to an axis of the outer thread (18) and in a mounted condition at least partially overlaps the end face (16) and the flange (20) of the tightening collar (6), wherein a sealing ring (8) at the end face (16) shows a free side to the axial direction and is com-pressed by an axial force produced by screwing the tightening collar (6) onto the outer thread (18).
