A damping valve for a hydraulic damper (D) comprises a valve housing comprising an inlet chamber and an outlet chamber. A housing valve seat is arranged between the inlet chamber and the outlet chamber. A valve element having a cylindrical first portion is slidably received in a cylindrical bore of the valve housing and a second portion has a valve surface for selectively engaging and disengaging the housing valve seat to allow passage of hydraulic fluid between the inlet chamber and the outlet chamber. A spring element is mounted within the valve housing for biasing the valve element into engagement with the housing valve seat. The bore of the valve housing has a closed end defining a bore chamber between an end of the first portion of the valve element and the closed end of the bore. A first passage provides fluid communication between the bore chamber and the inlet chamber.
