A central portion includes an inner member. An outer member defines together with said inner member first and second chambers adapted to contain a liquid, and gap means through which said first and second chambers communicate with each other. A reservoir is contained in said central portion and adapted to contain liquid. Passage means connect said reservoir to at least part of said chambers and are adapted to conduct liquid from said reservoir to said chambers and from said chambers to said reservoir. Movable members are disposed in said passages and arranged to present a lower resistance to the flow of liquid from said reservoir to said chambers than to the flow of liquid from said chambers to said reservoir. Said inner and outer members are angularly movable relative to each other and arranged to displace liquid between said first and second chambers through said gap means during such angular movement so as to perform a torsional damping action. |
