A torsional vibration damping device is disposed between an input front cover and a torque converter body for damping torsional vibration transmitted to an output member from an input member. The device includes a pair of side plates 20 and 21, a pair of cases 22 and 23. and a slider 25. The pair of side plates 20 and 21 are coupled together but spaced apart from one another and define an annular chamber therebetween. A piston 11 is coupled to the plates for axial movement but restricted from movement in a radial direction with respect to the plates. The pair of cases 22 and 23 is disposed between the side plates 20 and 21 within the annular chamber defining an arcuate chamber 24. The slider 25 is connectable to a driven plate 12 and is slidably disposed in the fluid chamber 24. Thee outer surfaces of the slider and tile inner surfaces of the fluid chamber 24 define a choke which restricts tile flow of fluid around the slider as it moves within the chamber. The cases 22 and 23 have overlapping portions which are pressed against each other by the pressure of tile fluid created Inside of the fluid chamber 24 in its radially outer portion.

A torque converter having a vibration damping mechanism comprising: a fluid filled torque converter housing having relatively rotatable input and output members; at least a first housing member coupled to said output member for limited rotary displacement therewith, said first housing member partially defining an annular chamber; first and second case members disposed within said annular chamber having overlapping portions defining an arcuate fluid chamber having a plurality of inner surfaces; and at least one restraining member connected to said first housing member for maintaining said first and second case members in generally constant engagement with one another; a slider element slidably disposed within said arcuate fluid chamber and coupled to said output member for movement therewith, said slider dividing said arcuate fluid chamber into two sub-chambers, said slider slideable within said arcuate fluid chamber, at least one surface of said slider and at least one of said inner surfaces defining a choke for restricting fluid flow between said sub-chambers in response to rotary displacement between said first housing member and said output member; a lock-up member coupled to said first housing member to rotate therewith and selectively engagable with said input member; and an annular seal member disposed proximate said slider, between said case members and said output member for sealing fluid within said sub-chambers.
