Abstract

A damping valve device (27), includes a damping valve housing (31) with a tube part (33) and an outer top housing part (35), wherein an intermediate housing wall (39) which is fixed with respect to the tube part (33) spatially separates a coil assembly (37) from a valve region (73), and the outer top housing part (35) forms a back iron body for the coil assembly (37), wherein an inner sleeve (69) together with a base (71) closes the valve region (73), wherein the outer top housing part (35) is a component part which is separate from the intermediate housing wall (39), and the inner sleeve (69) is connected to the intermediate housing wall (39) in a pressure-tight manner independent from the outer housing part (35), and wherein a protective cap (93) which is separate from the outer top housing part (35) covers the outer top housing part (35).
