Claim Text:
1. A suspension damper device comprising a housing adapted to be affixed, a suspension means supported by the housing and which may be tensed in a direction of suspension via a damper body of a damping means adapted to be connected to a component to be dampened, wherein in the damper body a damper piston fixedly connected to the housing is guided which physically separates two damper spaces in the damper body, whereby the two damper spaces are a cylinder space and an annual space, characterized in that three valves are provided whereby through these valves a volume flow of a fluid between the damping spaces is controlled during tensing of the suspension means in the direction of suspension, wherein the three valves each open a fluid connection between the cylinder space and the annular space when a respective predetermined pressure difference between the cylinder space and the annular space is exceeded during tensing of the suspension means in the direction of suspension, and close the fluid connection when the pressure difference drops below the respective predetermined pressure difference, and wherein the first valve comprises an annular valve body which is guided via the guide rod and is braced via a spring washer against an end face of the damper piston, said valve body clearing a first connection recess provided in the damper piston between the cylinder space and the annular space at said defined pressure difference against a resilient force of the valve spring.
