ABSTRACT:
A torsional vibration absorber device is positioned between two relatively rotatable members. A coupling member has a projection engaging a camming surface on one of the members, the camming surface being slanted circumferentially with respect to the axial direction. A wet type friction clutch is interposed between the coupling member and the other rotary member and is urged in the direction of its engagement upon axial movement of said coupling member, and a spring opposes such movement of the coupling member. A hydraulic oil chamber connected to atmosphere via an orifice decreases in volume upon axial movement of the coupling member.
