Abstract:
1. A flow control structure for cooling fluid control in a combustion chamber with a closed cooling system for a turbine, comprising: a flow control body for separate control of a cooling fluid inflow and a cooling fluid outflow for combustion chambers with a closed cooling system for turbines, wherein the flow control body has a cross-section with a non-rotationally symmetrical cross-sectional shape in a flow control section and the flow control body with a figure-of-eight shaped cross-section is inserted into a circular opening of the connecting piece, the circular opening surrounds the figure-of-eight shaped cross-section in the manner of a circumcircle, and the circular opening is inserted together with the figure-of-eight shaped cross-section of the flow control body in a circular recess in a combustion chamber wall in a sealing manner, the flow control body subdivides the circular recess into four segments, of which two are connected to a cooling fluid feed system and two to a cooling fluid discharge system and the flow control body and a shower insert are inserted in a connecting piece in a receptacle space disposed in the connecting piece, whereby the flow control body has structures that engage with the connecting piece in order to transmit a force flow.
