ABSTRACT:
The invention pertains to a damping valve(1), especially for hydraulic media in damping systems, such as shock or vibration damping systems and the like, with at least one throttling channel (38) equipped with a valve element for damping adjustment. The valve element at least partially covers the outlet mouth (40) of the throttling channel (38) and is designed as a leaf-spring element (42) clamped at one end, while the damping adjustment is accomplished by varying the length (1) of the free end of the leaf of the leaf-spring element (42).
