Holder for holding a metal component part of a turbine

Abstract

A holder for holding a metal component part, which has at least one internal passage which is accessible by an opening in an external surface of the component part. The holder is equipped with a bearing element, which comprises a bearing surface, which is designed in such a way that it allows a seating of the component part on the bearing element, and in this case serves as a support for at least a part of the external surface of the component part which has the opening, and a flow passage, which leads through the bearing element, with at least one outlet opening located in the bearing surface. The outlet opening is located in the bearing surface in such a way that, with the component part seated, it lies opposite the opening of the internal passage. Furthermore, the outlet opening in shape and flow cross section is adapted to the opening of the internal passage.

1 .- 12 . (canceled)  
   
   
       13 . A holder that supports a metal component part having at least one internal passage accessible by an opening in an external surface of the component part, comprising: 
 a bearing element having a bearing surface configured to facilitate seating of the component part on the bearing element, and supports a portion of the external surface of the component part which has the opening; and    a flow passage arranged in the holder having an outlet opening located in the bearing surface wherein: 
 the outlet opening is aligned and opposite the opening of the internal passage of the component part when the component part is seated in the holder, and  
 the outlet opening is adapted to a shape and a flow cross section of the opening of the internal passage, and  
 the outlet opening is located on a connector that projects beyond the bearing surface of the bearing element and where the outlet opening is arranged at a distance from the bearing surface, and  
 the connector is arranged and configured to insert into the opening in the external surface of the component part.  
   
   
   
       14 . The holder as claimed in  claim 13 , wherein an edge of the outlet opening is encompassed by a seal which projects beyond the bearing surface.  
   
   
       15 . The holder as claimed in  claim 14 , wherein the flow passage has a plurality of closable outlet openings arranged at different locations of the bearing surface.  
   
   
       16 . The holder as claimed in  claim 15 , wherein the shape of the bearing surface corresponds to a shape of the external surface of the component part which is to be supported.  
   
   
       17 . The holder as claimed in  claim 16 , wherein the connector is adjacent to the opening in the external surface of the seated component part, and the shape and opening cross section of the outlet opening corresponds to the shape and the opening cross section of the internal passage.  
   
   
       18 . The holder as claimed in  claim 17 , wherein the edge of the outlet opening is encompassed by a seal that projects in the direction of a longitudinal axis of the connector.  
   
   
       19 . The holder as claimed in  claim 18 , wherein the connector projects into the opening in the external surface of the seated component part.  
   
   
       20 . The holder as claimed in  claim 19 , wherein the shape and the dimension of the external circumference of the connector corresponds to the shape and the dimension of the opening in the external surface of the seated component part.  
   
   
       21 . The holder as claimed in  claim 20 , wherein an external dimension of the connector is smaller than the flow cross section of the internal passage of the holder.  
   
   
       22 . The holder as claimed in  claim 21 , wherein the outer circumferential surface of the connector is encompassed by a seal along a section of the connector that adjoins the bearing surface and extends over a portion of a length of the connector.  
   
   
       23 . The holder as claimed in  claim 22 , wherein the flow passage has a chamber in the bearing element and a plurality of closable chamber openings located in the bearing surface, and in which connectors are provided with through-openings, and in a region of the chamber openings are fixable on the bearing element such that the through-passage of a fixed connector aligns with one of the chamber openings.  
   
   
       24 . The holder as claimed in  claim 23 , wherein the component part is a turbine component part.
