Abstract: Dampers for vehicle suspensions include a housing comprising a tube attached to a wheel axle of a vehicle and a piston rod extending from a piston within the tube and attached to the vehicle body. The piston divides the tube into first and second chambers. In order to damp responses when minor smooth road imperfections impart low force excitations to the wheel of the vehicle, a fluid bypass passageway in the form of a sleeve is positioned around the tube and overlies the piston.

The sleeve communicates with the first and second chambers through metered orifices or valves. As low force excitations from smooth road imperfections displace fluid within the tube through the metered orifices or valves, the orifices damp responses to the low force excitations, thereby smoothing the ride of the vehicle.
