A damping valve (2) for a hydraulic damper (D) comprises a valve housing (4) comprising an inlet chamber (20) and an outlet chamber (22). A housing valve seat (28) is arranged between the inlet chamber (20) and the outlet chamber (22). A valve element (6) having a cylindrical first portion (8) is slidably received in a cylindrical bore (10) of the valve housing (4) and a second portion has a valve surface for selectively engaging and disengaging the housing valve seat (28) to allow passage of hydraulic fluid between the inlet chamber (20) and the outlet chamber (22). A spring element (40) is mounted within the valve housing (4) for biasing the valve element (6) into engagement with the housing valve seat (28). The bore (10) of the valve housing (4) has a closed end defining a bore chamber (76) between an end (56) of the first portion of the valve element (6) and the closed end of the bore (10). At least one first passage (A) provides fluid communication between the bore chamber (76) and the inlet chamber (20). At least one second passage (B) provides fluid communication between the bore chamber (76) and the inlet chamber (20). A one-way valve (63) is located in the at least one second passage (B) and is configured to allow flow in the at least one second passage (B) in a direction from the inlet chamber (20) to the bore chamber (76), but to block flow in the at least one second passage (B) in a direction from the bore chamber (76) to the inlet chamber (20).
