ABSTRACT:
A rubber flap type damper valve, particularly intended for incorporation in a hydraulic suspension unit for a vehicle, the valve including rubber flaps which are precompressed resiliently against bump and rebound ports in a port plate, the invention being characterized in that each rubber flap covers one or more ports with each port so covered consisting of a hole of a diameter not exceeding 3 mm with the object of preventing the rubber flaps from becoming adhered to the port plate by sticking in the holes thereof. As a further measure of preventing adherence of the flaps to the port plate the undersurface of each flap may be corrugated, or otherwise rendered uneven. Respective different flaps may be precompressed against the port plate to different extents.
