A guide vane ring of a turbomachine, in particular of an axial-throughflow turbine, includes a vane group () having a plurality of vanes (). The vane group () has a vane root () which has two flanges (). The vane group () is fastened to a vane carrier by means of the flanges (). In order to reduce stresses in the vanes () which occur during deformations of the vane carrier, one flange () has on a front end portion () and on a rear end portion (), radially on the inside and radially on the outside, in each case a contact zone () which bears against the vane carrier. The other flange () has on one end portion (), radially on the inside, a contact zone () which bears against the vane carrier, and is spaced apart from the vane carrier radially on the outside. Moreover, this flange () has on the other end portion (), radially on the outside, a contact zone () which bears against the vane carrier, and is spaced apart from the vane carrier radially on the inside. Furthermore, the flanges (), between their end portions (), are spaced apart from the vane carrier radially on the inside and radially on the outside.

A turbine blade for a gas turbine has a hollow airfoil extending from a platform. There is a fillet between the airfoil and the platform, both on the pressure side and on the suction side of the airfoil. The fillet contains a cooling bore extending along part of the length of the fillet, having a first end communicating with the interior of the turbine blade for receiving a gaseous coolant and a second end communicating with the exterior of the turbine blade. The cooling may be formed by electro-discharge machining.

The present invention relates to a sealing arrangement which is formed between a rotating assembly () and a static assembly (). In this sealing arrangement, the rotating assembly () has at least one cutting element () which engages in a counterpart surface on the static component. The present sealing arrangement is distinguished by the fact that the cutting element () is designed as a chipping device with a geometrically determined cutting edge with respect to the counterpart surface () or forms a chipping device of this type when the rotating assembly is rotating. The proposed sealing arrangement reduces the wear to the cutting element even in the event of adverse rotation or temperature conditions.

A device for producing a soldered joint between two joining partners which can be joined via a common contact surface ( ), using a solder material which can be introduced between the two joining partners. At least one joining partner ( ), in the region of the contact surface ( ), provides at least one recess, known as a solder reservoir ( ), which faces the contact surface and into which the solder material can be introduced, and the solder reservoir ( ) is completely delimited and surrounded by the contact surface ( ).
