Abstract

An adjustable hydraulic damper comprises a cylinder 3 divided by a damping piston 2 into upper and lower working chambers 4 and 5. A bypass valve 10 is provided in the region of the base 12 of the damper and damps vibrations in parallel with a throttle member 6 in the piston. The bypass valve 10 regulates the cross-sectional area of a bypass passage 14, 11 which connects the upper working chamber 4 with the surrounding compensating chamber 9. The provision of the valve 10 in the region of the base 12 of the damper enables the damper to be used not only as a vibration damper but also as a wheel-locating suspension strut and as a suspension strut cartridge. The valve 10 may be adjusted electromagnetically. There may be a plurality of tubular passages 14 passing through the compensating chamber 9, each controlled by a valve in the base. The bypass passage may instead be annular and surround the inner or outer cylinder.
