Damping device for rotary elastic coupling has relatively rotatable inner and outer rings with intermediate pressure element acting on pressure medium chamber communicating with equalization chamber

摘要

The damping device has radially spaced inner and outer rings (2,3) which can rotate relative to one another about a rotation axis (1), with a pressure element (4) contained in the radial gap (13) between the rings having peripheral pressure surfaces (14,14'), each acting against a pressure plate (8,8') delimiting a working chamber (5,5') filled with a pressure medium. Each working chamber communicates with an equalization chamber (6,6') via at least one overflow opening (9), through which the pressure medium flow upon relative rotation between the 2 rings.
