  • Patent number: 11808173
    Abstract: A scroll passage of a turbine housing includes: an outer peripheral surface extending along an axial direction of the turbine housing; an inner peripheral surface disposed inward of the outer peripheral surface; a one-side surface extending along the radial direction; an other-side surface disposed closer to an outlet of the housing; a one-side outer peripheral R portion connecting the one-side surface and the outer peripheral surface; an other-side outer peripheral R portion connecting the other-side surface and the outer peripheral surface; and an other-side inner peripheral R portion connecting the other-side surface and the inner peripheral surface. A ratio of a width dimension of the scroll passage to an R dimension of each portion is defined as a peripheral R ratio, and the peripheral R ratio has an R ratio increasing region the ratio increases from upstream to downstream in the scroll passage.

  • Publication number: 20230287831
    Abstract: A turbine housing is configured to house a turbine wheel to be driven with exhaust gas discharged from a gasoline engine. The turbine housing includes: a body part including a scroll passage wall surface, an exhaust gas discharge path wall surface, and a wastegate passage wall surface provided inside the body part, the scroll passage wall surface forming a scroll passage having a scroll shape for guiding the exhaust gas to the turbine wheel, the exhaust gas discharge path wall surface forming an exhaust gas discharge path for discharging the exhaust gas having passed through the turbine wheel, the wastegate passage wall surface forming a wastegate passage connecting the scroll passage and the exhaust gas discharge path to each other while bypassing the turbine wheel; and an entrance flange part provided at an upstream end of the scroll passage in the body part, the entrance flange part including an exhaust gas inlet leading to the scroll passage.

  • Publication number: 20220213900
    Abstract: A supercharger is provided with: a housing; a rotary shaft that is supported inside the housing to be freely rotatable; a compressor wheel that is provided at one end in an axial direction of the rotary shaft; a cooling water supplying pipe and a cooling water discharging pipe that have a flange part at an end and are connected to the housing; and a lubricant supplying pipe that has a flange part at an end and is connected to the housing. The ends of the cooling water supplying pipe and the cooling water discharging pipe are inserted into a cooling water supplying flow path and a cooling water discharging flow path of the housing, respectively. The end of the lubricant supplying pipe is inserted into a first supplying flow path of the housing. The flange part presses the flange parts in an insertion direction and is fixed to the housing.
