Abstract

A power transmission mechanism for transmitting power between a driving engine and an output drive, including: an input and an output; a hydrodynamic component with a pump wheel and a turbine wheel; an apparatus for at least partially bridging over the hydrodynamic component, the apparatus including a control device with a piston element that is chargeable with pressurizing agent; an influencing element for influencing a difference in speeds of rotation of moving fluids on both sides of the piston element, the influencing element rotatable in rotational synchronicity with the piston element, which extends outward in the radial direction free of any direct connection with the piston element, and which is situated in the radial direction at least in the range of the outside diameter, forming at least part of an axial space with the piston element.
