Abstract:
The invention relates to a damping element for a vibration damper that works with hydraulic damping fluid. The fundamental structure of the damping element includes a one-piece base body configured as a circular disk, which has a plurality of first flow-through openings, each having an entry cross-section in a first face side of the base body, as well as a plurality of second flow-through openings, each having an entry cross-section in an opposite, second face side of the base body, as well as circular valve disks on both face sides of the base body, which rest against a support surface of the base body, disposed in the center, and at least partially close off exit cross-sections of the flow-through openings. The exit cross-sections are surrounded by control edges, which form contact surfaces for the valve disks and project beyond the support surface as well as the entry cross-sections. The height of the control edges increases with an increasing radial distance from the center point of the base body in the form of a circular disk. According to the invention, the flow-through openings have a flow channel section that is preferably cylindrical and opens into a larger exit cross-section bordered by the control edges.
