ABSTRACT:
A motor vehicle suspension system for damping vibrations between, for example, the wheels of the motor vehicle and the body of the motor vehicle, can have a vibration damper unit with two fluid chambers therein and separated from one another by a piston unit. In addition, there can be a fluid bypass connecting the two chambers. A shut-off valve device can be disposed between two portions of the fluid connection to separate a high-pressure section and a low-pressure section, and the latter shut-off valve has a shutoff body which can be adjusted by an external control by means of a magnet armature and a magnet coil between a closed and an open position. The high pressure section empties into a central channel, and a first side of the shut-off valve body which is pressurized by the high pressure section can be elastically pressed against a shut-off valve seat by means of a compression spring, whereby the first side of the shut-off valve body is connected by means of an after-throttle to a second side of the shut-off valve body. Within the fluid connection there can be a segment which provides a pressure reduction by means of at least one throttle point in combination with a baffle device which is connected to the throttle point.
