MUMBAI, India, Sept. 26 -- Intellectual Property India has published a patent application (202517080804 A) filed by Cummins Ltd., London, on Aug. 26, for 'variable geometry turbine.'
Inventor(s) include Hinchliffe, Kyle; Normington, Christopher; Edwards, Matthew William; and Holroyd, Robert L.
The application for the patent was published on Sept. 26, under issue no. 39/2025.
According to the abstract released by the Intellectual Property India: "A nozzle ring (312) for a variable geometry turbine comprises: a generally annular wall (18); an inner flange (19); an outer flange (20); and two protrusions (330, 332). The inner and outer flanges are generally perpendicular to the generally annular wall and extend from a radially inner and outer edge of the generally annular wall. The two protrusions extend from one of the inner or outer flange towards the other one of the inner or outer flange. At least one of the two protrusions extends only partially towards the other one of the inner or outer flange. The two protrusions define a first gap (136) therebetween. The generally annular wall and the two protrusions define a second gap (338) between the generally annular wall and both of the two protrusions. In some embodiments, the two protrusions are such that the first gap is tapered so that a dimension of the gap is smaller at a distal end of the protrusions and larger proximate to the inner or outer flange from which the two protrusions extend. In some embodiments, a radial extent of the second gap is less than a radial extent of the two protrusions. In use, the second gap receives an arcuate head portion (48) of a support (124) and the first gap receives an intermediate portion (56) of the support. The nozzle ring may be suitable for use in a variable geometry turbocharger."
The patent application was internationally filed on Jan. 26, 2024, under International application No.PCT/GB2024/050215.
