Beschreibung
Zusammenfassung:	A damping valve apparatus, comprising a valve sleeve (1110), a first valve core (1120), and a second valve core (1130). The first valve core and second valve core are each located in the valve sleeve, the first valve core is configured to move axially relative to the second valve core, and the second valve core comprises an annular main body part and an end cover part; the end cover part is located on the side of the annular main body part closest to the first valve core, and the end cover part is provided with a through hole axially passing through the end cover; an orthographic projection of an end face of the first valve core closest to the second valve core onto a reference plane at least partially falls within an orthographic projection of the end cover part onto the reference plane, an orthographic projection of the end surface onto the reference plane encircles an orthographic projection of the through hole onto the reference plane, the reference plane is perpendicular to the axial direction, and the a
