Patent ID: 6948707

Claim:
A stabilizer bar for an automotive vehicle, said stabilizer bar comprising: first and second torsion rods which are aligned along an axis; a housing connected to the first torsion rod such that it will rotate with the first rod; a rotor located within the housing and connected to the second rod such that it will rotate with the second rod; the rotor having a face that is presented axially and is provided with ramps; a piston located within the housing such that it can shift axially with respect to the housing, but not rotationally, the piston together with the housing defining a cavity, the volume of which depends on the axial position of the piston in the housing, the piston having a face that is presented axially toward the face on the rotor and has ramps which are presented toward the ramps on the rotor, the ramps on the piston cooperating with the ramps on the rotor, as a consequence of relative rotation between the rotor and the piston and housing, to determine the axial position of the piston in the housing and the size of the cavity; a fluid in the cavity of the housing; and a valve for controlling the flow of fluid displaced from the cavity when the cavity decreases in volume.
