Patent ID: 8272985

Claim:
A power transmission mechanism for transmitting power between a driving engine and an output drive, comprising: an input and an output; a hydrodynamic component with a pump wheel, a turbine wheel, and a cover forming the input; 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, the piston element including an outside diameter; and, an influencing element for influencing a difference in speeds of rotation of moving fluids on either side of the piston element, the influencing element: axially located between the piston element and the turbine wheel; rotatable in rotational synchronicity with the piston element; free of any direct connection with the piston element; situated radially inward of the outside diameter; and, forming at least part of an axial space with the piston element.
