  • Patent number: 10774896
    Abstract: A method for operating a controllable shock absorber may involve damping movement of a valve body by loading the valve body with a back pressure on an outflow side. Further, the controllable shock absorber may include a cylinder tube, a piston within the cylinder tube that divides the cylinder tube into two working spaces and includes a couple fluid leadthroughs connecting the working spaces, and first and second valve assemblies for damping piston movement in first and second actuating directions that are disposed on the leadthroughs. Each valve assembly may have a pilot control chamber and a valve plate that is either seated on or spaced apart from a valve seat in closed and open valve positions. Each valve plate can be prestressed closed by pressure loading the pilot control chamber. The pressures of the pilot control chambers can be set by a pilot control valve that comprises a movable valve body. As a result, an outflow cross section between the pilot control chambers and the working spaces can be set.

  • Patent number: 10704642
    Abstract: A piston/damper tube assembly may include a damper tube with damping fluid, a movable piston rod, a working piston, a controllable 4-way bottom valve with a control member, and a compensation space. Two flow passage ways of the bottom valve connect the working space remote from the piston rod via the control member to the compensation space. Two control ways of the bottom valve load the control member on a first side with a pressure of the piston rod-side working space and on a second side with a pressure of the compensation space. The control member may control the flow passage ways in a manner dependent on the pressure of the piston-rod-side working space that prevails on the control member on the first side via a fluidic connection, and on the pressure of the compensation space that prevails on the control member on the second side via an opening.
