Abstract
A starting element () for use, for example, in a drivetrain of a motor vehicle, includes a piston () which divides a first volume () that can be filled with a fluid from a second volume () that can be filled with a fluid, wherein the piston () comprises at least one fluid passage () which allows the fluid at least occasionally to pass through the piston () from the first volume () into the second volume () and/or from the second volume () into the first volume (). The at least one fluid passage () comprises a passage component part () and a receiving opening () in the piston (). The passage component part () is inserted into the receiving opening so that at least one passage opening () is formed which allows the fluid to pass through at least occasionally.
