Suspension Strut with a Spring Device and a Vibration Damper

A suspension strut with a spring device and a vibration damper with a cylinder configured to receive damping fluid and a working piston axially movable therein, which is coupled to a piston rod having a longitudinal axis, the working piston dividing an interior of the cylinder into a first working space and a second working space, and with a valve device adapted to control the flow of damping fluid between the first and second working spaces, and an electrically actuated solenoid for actuating valve means of the valve device for changing a flow passage of the valve device between the first and second working spaces, the suspension strut having a first receptacle having a housing, on which the piston rod is supported, the first receptacle adapted for arranging the suspension strut on a first body element of a vehicle, the suspension strut having a second receptacle adapted for arranging the suspension strut on a second body element of the vehicle, the suspension strut having a travel measuring device for detecting the current spring travel of the suspension strut, wherein the housing has an inner recess and the travel measuring device has a magneto-operative sensor device, arranged in the inner recess, adapted to detect a magnetic field of a magnet device spaced apart from the sensor device.
