Abstract: A rotary damper for use in motor vehicle suspensions comprising a rotor disposed within damping fluid in a fluid chamber of a case to form fluid volumes, with valves for flow control and an accumulator for fluid fill variation and thermal expansion mounted internal to the rotor. A first check valve and first control valve mounted in a first flow passage within the rotor allow flow from second fluid volume to first fluid volume, but restrict flow from the first fluid volume to the second fluid volume. Similarly, a second check valve and a second control valve mounted in a second flow passage within the rotor allow flow from the first fluid volume to the second fluid volume, but restrict flow from the second fluid volume to the first fluid volume. Thus, the valves are configured to provide independent control of damping for each direction of rotation.

Abstract: A rotary damper for use in motor vehicle suspensions comprising a rotor disposed within damping fluid in a fluid chamber of a casing to form inner fluid volume and outer fluid volume, with first valve and second valve for controlling flow between the inner fluid volume and the outer fluid volume, and an accumulator using closed cell foam as a compressible material for fluid fill variation and thermal expansion. First valve controls flow from the outer fluid volume to the inner fluid volume for one direction of rotation of the rotor, while second valve controls flow from the inner fluid volume to the outer fluid volume for the opposite rotation of the rotor. Thus, the valves are configured to provide independent control of damping for each direction of rotation. A valve holder supporting the valves and providing flow passages is designed for powdered metallurgy fabrication.
