Abstract
The present disclosure relates to a damping device for absorbing structural vibrations or high excitation frequencies between a first component and a second component of a turbomachine, particularly in connection with high temperature operating conditions. The first component may be a combustor or a burner of a gas turbine and the second component may be a fuel supply line, connected to or passed through a wall of the first component. The damping device may include at least one wire mesh element which is inserted into a housing with a radially outer surface of the wire mesh element being compressed by the housing, and a radially inner surface of the wire mesh element closely surrounding the second component, wherein the housing is fixedly connected to the wall of the first component by a weld seam.
