Embodiment Construction

[0091] figure 1 Shown is a damping valve arrangement 1 , which is fastened, for example, to a piston rod 3 of a shock absorber, which is only partially shown. The damping valve arrangement 1 comprises a piston 5 which divides the cylinder 7 into a piston rod-side working chamber 9 and a piston rod-distal working chamber 11 which are filled with a damping medium. In this exemplary embodiment, the damping valve arrangement is fixed on the piston rod 3 , however, the invention is not restricted to this type of arrangement.

[0092] An actuator 15 of any desired design is arranged in the outer housing 13 , wherein in this exemplary embodiment an electromagnetic coil 17 is used as an actuator, which exerts a force on an axially movable armature 19 , which is controlled by to the multi-part pilot valve body 21 of the pilot valve 23 . The structure of the pilot valve body and figure 2Get in touch for a detailed description. At least one valve spring (in this variant two countera...

Abstract

An adjustable damping valve arrangement for a vibration damper comprises an actuator which exerts an actuating force on an auxiliary valve body of an auxiliary valve. The auxiliary valve influences a closing force on a main stage valve. A pressure depending on the pressure level in a working space of the vibration damper acts on at least one pressure-impinged closing surface of the main stage valve via a flow connection. The flow connection is carried out so as to be functionally parallel to an incident flow of the main stage valve, and a flow-in opening of the flow connection is oriented at an angle of at least 60 DEG to the flow direction into the main stage valve so that only a static pressure acts on the closing surface of the main stage valve.

Description

technical field [0001] The invention relates to an adjustable damping valve arrangement according to the preamble of claim 1 . Background technique [0002] Document DE 10 2008 041 735 B3 relates to a class-forming adjustable damping valve arrangement, the main valve body of which has two pressure-loaded surfaces acting in the closing direction. The design of the main valve also offers the advantage that its enlarged closing surface simplifies the design of the design of the bore surface in the pulling direction. The design of the damping valve arrangement increases the achievable damping force in the pressure direction. An increase in the damping force can definitely be desired, for example, if a larger damping force range is covered with a predetermined actuator force. [0003] However, a damping force characteristic curve that is as smooth as possible is also desired. There is then a clear return to a design which has only one pressure-loaded surface on the main valve ...
