Patent number: 11697997Abstract: A turbine for a turbo-machine is proposed in which, at a gas inlet for a turbine wheel, vanes extend from a nozzle ring though slots in a shroud. The nozzle ring and shroud are relatively rotatable about a rotational axis of the turbine by at least 0.1 degrees. In use, the nozzle ring and shroud are relatively rotated to bring one side of the vane into close contact with one surface of the slot, to inhibit leakage of gas between the vane and the slot surface. For this purpose the respective surfaces of the nozzle and slot can be configured to closely conform to each other. If there is differential thermal expansion of the shroud and nozzle ring, the nozzle ring and shroud can relatively rotate, to withdraw the vane from the edge of the slot to relieve the pressure between them.Type: GrantFiled: April 25, 2022Date of Patent: July 11, 2023Assignee: Cummins Ltd.Inventors: Matthew William Edwards, Karl Conlon, Simon David Moore, Christopher Parry, Andrew Sullivan, Paul Ghosh, Mark R. Holden, George E. Sandford, Nandakishore Arcot Madhusudan, Stephen David Hughes, Christopher J. Shaw

Patent number: 11578645Abstract: A valve system comprising a valve chamber at a junction of an inlet port, an outlet port and a bypass port, the inlet port configured for fluid communication with exhaust gas, the outlet port configured for fluid communication with an inlet of a turbine, and the bypass port configured for fluid communication with an exhaust aftertreatment device; a rotary valve comprising a valve rotor which rotates about a valve axis within the valve chamber between a first position to permit gas flow through the bypass port and a second position to block gas flow. At least one of the valve rotor and the valve chamber comprises a protrusion and the other comprises a recess, wherein, in the first position, the protrusion and recess are spaced from one another, and, in the second position the recess receives the protrusion such that gas flow between the protrusion and recess is substantially prevented.Type: GrantFiled: March 1, 2022Date of Patent: February 14, 2023Assignee: CUMMINS LTD.Inventors: Robin Daniels, Thomas Morton, Thomas Roberts, Christopher Parry, Richard Goodyear, Mark R. Holden, Donald E. Willey

Patent number: 11536192Abstract: A rotary turbine bypass valve comprises a valve chamber positioned at a junction of an inlet port, an outlet port and a bypass port, the inlet port configured for fluid communication with a flow of exhaust gas from an engine, the outlet port configured for fluid communication with an inlet of a turbine, and the bypass port configured for fluid communication with an exhaust aftertreatment device; and a valve rotor supported for rotation, about a valve axis, within the valve chamber. The valve rotor is rotatable about the valve axis between a first position in which the valve rotor permits gas flow through the bypass port and a second position in which the valve rotor blocks gas flow through the bypass port.Type: GrantFiled: August 22, 2018Date of Patent: December 27, 2022Assignee: CUMMINS LTD.Inventors: Robin Daniels, Gareth Williamson, Ross Deacon, Laith Al-Kazaz, Thomas Morton, Christopher Parry, Richard Goodyear, Mark R.

Patent number: 10086261Abstract: An online game is provided to players where players may participate in individual episodes of the online racing game. The individual episodes may include individual races within the racing game in which players control game entities through racecourses. User accounts comprising an indication of game entities associated with the players of the online game, an indication of a status of the player, and a game play metric associated with the player may be managed. Races in the online game may be synthesized by simulating participation by game entities of a player in individual synthetic episodes of the online game while the player is absent from the online game. A change in the game play metric of the player may be determined based on the performance of the first game entity in the race of the first synthetic episode.Type: GrantFiled: February 7, 2014Date of Patent: October 2, 2018Assignee: Kabam, Inc.Inventors: John Kim, Kevin Lee, Kevin Chanthasiriphan, Steven Andrew Martin, William Kim, William Christopher Parry
