Abstract
A shock absorber with a check valve device and a check valve device for a shock absorber is disclosed. The check valve device located in the bypass of a shock absorber between a high-pressure segment and a low-pressure segment has a check valve which can be moved by an external control into a standby opening status, in which the actual opening can be performed as a function of the pressure prevailing in the high-pressure segment, when the pressure falls below a predetermined value. By coordinating the stroke distance of a check valve body with a magnet armature, and taking into consideration a control chamber discharge cross section, noises and fluctuations of the damping force characteristic can be eliminated even with a very soft comfort setting of the check valve device.
