Movement stage for a hydraulic shock absorber and shock absorber with the movement stage

A movement stage for a hydraulic shock absorber comprising:

• a damping volume filled with an incompressible damping fluid;
• a stage throttle having a disk valve with a valve disk, an analogue piston and an elastic spring configured to bias the valve disk in a closing direction of the disk valve;
• said stage throttle being arranged so that the damping fluid flows through the stage throttle in a direction opposite to the closing direction of the disk valve as the shock absorber moves in one movement direction;
• said disk valve being configured to generate a shock absorber resistance force;
• said elastic spring being supported on the analogue piston and on the valve disk to elastically couple the analogue piston via the elastic spring with the disk valve;
• said valve disk having a valve disk pressure surface;
• said valve disk pressure surface being a portion of a surface of the disk valve that is arranged upstream of an entry edge of a disk valve seat;
• said analogue piston having an analogue piston pressure surface facing away from the valve disk pressure surface;
• said analogue piston pressure surface being arranged to face away from the elastic spring;
• said valve disk pressure surface and said analogue piston pressure surface being directly impinged by the damping fluid flowing out of the damping volume during the movement of the shock absorber in the one movement direction;
• and,
• said analogue piston pressure surface being larger than said valve disk pressure surface when projected in the closing direction of the disk valve so that a bias of the valve disk is increased when the analogue piston is displaced towards the elastic spring as the shock absorber moves in the at least one movement direction.
