Intellectual Property India Publishes Patent Application for 'Guide Device For A Turbine' Filed by Borgwarner Inc.

MUMBAI, India, April 20 -- Intellectual Property India has published a patent application (202514091610 A) filed by Borgwarner Inc., Auburn Hills, U.S.A., on Sept. 24, 2025, for 'guide device for a turbine.'

Inventor(s) include Schmitt, Frank.

The application for the patent was published on April 17, under issue no. 16/2026.

According to the abstract released by the Intellectual Property India: "The present invention relates to a guide device (100) for a turbine (10), comprising a vane bearing ring (110), a cover disk (150) which is arranged parallel to the vane bearing ring (110) and spaced apart therefrom in the axial direction (22) by spacer elements (160), and a plurality of adjustable guide vanes (120) which are each mounted rotatably and adjustably in the vane bearing ring (110). The adjustable guide vanes (120) are arranged between the cover disk (150) and the vane bearing ring (110). The adjustable guide vanes (120) are adjustable between a first guide vane position, in which the guide vanes are minimally open, and a second guide vane position (122), in which the guide vanes are maximally open. During operation of the guide device (100), the respective guide vane position is linked to a corresponding mass throughput through the guide device (100), in particular the mass throughput being 100% in the second guide vane position. The vane bearing ring (110) and/or the cover disk (150) has/have a bevel (200, 200a, 200b) which, on a side (111, 151) of the vane bearing ring (110) and/or of the cover disk (150) facing the adjustable guide vanes, extends from an inner circumference (112, 152) of the vane bearing ring (110) and/or of the cover disk (150) in the radial direction (24) as far as a bevel outer radius (RA), The adjustable guide vanes (120) each have a guide vane trailing edge (123). In the case of guide vane positions corresponding to a mass throughput range from a first mass throughput value to a second mass throughput value, the guide vane trailing edge (123) lies in the radial direction (24) in the region of the bevel (200, 200a, 200b), the first mass throughput value being at most 35%."
