Publication number: 20240084715Abstract: A turbine includes a turbine wheel, a housing having a flow path for a gas, a variable geometry device to guide the gas from the flow path to the turbine wheel, and a biasing member. The variable geometry device includes one or more nozzle vane member, each having a nozzle vane, a nozzle shaft and a nozzle link plate. The biasing member is in contact with the nozzle link plate of the nozzle vane member, to urge the nozzle vane member against a contact surface of the turbine.Type: ApplicationFiled: November 15, 2023Publication date: March 14, 2024Inventors: Kenichi SEGAWA, Hayato SHIBAYAMA, Takao ASAKAWA, Kengo IKEDA, Naotoshi SHIMIZU, Taiki YOSHIZAKI, Ryosuke MIYAO

Patent number: 10781823Abstract: An impeller includes: a main body portion which is increased in diameter from one side to another side in a rotation axis direction; a thinned portion, which is formed in a back surface of the main body portion so as to be oriented toward the another side in the rotation axis direction, and is recessed toward the one side in the rotation axis direction; a plurality of full blades which are formed on an outer circumferential surface of the main body portion so as to be oriented toward the one side in the rotation axis direction; and a plurality of splitter blades, which are formed on the outer circumferential surface, and have end portions being located on the one side in the rotation axis direction and being positioned on the another side in the rotation axis direction with respect to the full blades.Type: GrantFiled: March 27, 2018Date of Patent: September 22, 2020Assignee: IHI CorporationInventors: Taiki Yoshizaki, Koutarou Itou, Takashi Yoshida, Takuya Ozasa, Kuniaki Iizuka

Patent number: 10302012Abstract: A plurality of variable nozzles is provided at equal intervals in a circumferential direction so as to surround a turbine wheel between a facing surface of a first nozzle ring and a facing surface of a second nozzle ring. The first nozzle ring is constituted by three nozzle ring segments laminated along the axial direction. In the three nozzle ring segments, a thickness of the nozzle ring segment on a side far from the bearing housing is smaller than a thickness of the nozzle ring segment on a side close to the bearing housing.Type: GrantFiled: January 25, 2017Date of Patent: May 28, 2019Assignee: IHI CorporationInventors: Taiki Yoshizaki, Koutarou Itou

Patent number: 10208660Abstract: A support ring is connected to a first nozzle ring by multiple connecting pins. An outer cutout is formed at a region on an outer side in a radial direction at a rim on an axially one side of each first attachment hole in the first nozzle ring. An inner cutout is formed at a region on an inner side in the radial direction at the rim on the axially one side of each first attachment hole in the first nozzle ring. An outer cutout is formed at a region on an outer side in the radial direction at a rim on an axially other side of each pin hole in the support ring. An inner cutout is formed at a region on an inner side in the radial direction at the rim on the axially other side of each pin hole in the support ring.Type: GrantFiled: December 5, 2016Date of Patent: February 19, 2019Assignee: IHI CorporationInventors: Jose Javier Bayod, Koutarou Itou, Taiki Yoshizaki

Patent number: 10125673Abstract: In a variable nozzle unit, at a position located away from and opposed to a first nozzle ring in a right-left direction, a second nozzle ring is provided integrally with the first nozzle ring through multiple connecting pins arranged in a circumferential direction. An inner edge portion of a support ring is connected to the first nozzle ring by riveting of one end portions of the multiple connecting pins. Each pin hole in the support ring is formed into such a shape extending in a radial direction of the support ring. A washer is provided between a rim of each pin hole in the support ring and a rivet head brought about by joining of the end portion of the corresponding connecting pin.Type: GrantFiled: November 10, 2016Date of Patent: November 13, 2018Assignee: IHI CorporationInventors: Jose Javier Bayod, Koutarou Itou, Taiki Yoshizaki, Tomohiro Inoue, Kenji Bunno, Takao Asakawa, Ryota Sakisaka, Kazuko Takeuchi
