A turbocharger includes a housing and a rotating group supported for rotation within the housing. The rotating group includes a compressor wheel disposed within a compressor section of the turbocharger, and the rotating group includes a turbine wheel disposed within a turbine section of the turbocharger. The turbine wheel includes a bleed pressure surface. The turbocharger further includes a bleed passage that extends at least partly through the housing to fluidly connect the compressor section to the turbine section. The bleed passage is configured to direct a bleed flow of fluid from the compressor section to the bleed pressure surface to supply a thrust counterbalance load to the bleed pressure surface.

A turbomachine includes a first housing member having a first journal bearing portion and a first radial control surface. The turbomachine also includes a second housing member with a second journal bearing portion and a second radial control surface. The second radial control surface has an interference fit with the first radial control surface that radially aligns the second journal bearing portion and the first journal bearing portion along a common axis.

A compressor device includes a motor cooling system that provides a first flow of a first fluid through a housing for cooling a motor. The motor cooling system includes a first fluid flow section at a first axial position. The first fluid flow section extends in a downstream direction radially with respect to the axis of rotation. Also, the device includes a bearing cooling system that provides a second flow of a second fluid through the housing for cooling the bearing. The bearing cooling system includes a second flow section at a second axial position that is spaced apart axially from the first axial position. The second flow section extends in a downstream direction radially with respect to the axis of rotation. The first flow section and the second flow section are disposed in a heat exchanger arrangement configured to transfer heat between the second fluid and the first fluid.

An assembly kit includes a first turbocharger component flange with receptacles spaced according to a first interval angle; a second turbocharger component flange with receptacles spaced according to a second interval angle that differs from the first interval angle; and a piece configured for receipt by a receptacle of the first component and a receptacle of the second component where alignment of the receptacles determines a rotational orientation angle of the first component with respect to the second component. Various other examples of devices, assemblies, systems, methods, etc., are also disclosed.

A turbocharger with a two-stage compressor having first- and second-stage impellers mounted on a common shaft in a back-to-back configuration. The first-stage impeller has a boreless configuration, defining an unthreaded pilot hole receiving an unthreaded end of the shaft so as to establish a coaxial relationship between the impeller and the shaft. The first impeller further defines a hollow cylindrical pilot member that projects from the back of the impeller and is received in a portion of the bore through the second-stage impeller to position the impellers coaxially with each other. The shaft passes through the pilot member and is externally threaded for engaging threads on the inner surface of the pilot member to secure the impellers to the shaft. The bore of the second impeller has a second portion that engages an outer cylindrical surface of the shaft to establish a coaxial relationship between the shaft and impeller.

A two-stage radial compressor having a ported second-stage shroud, forming a passive surge control system. Thus, some proportion of the fluid is allowed to flow between the second-stage of the compressor in the vicinity of the impeller blade tips, through a port in the shroud into an upstream portion of the compressor flow path that leads into the second-stage impeller inlet. The fluid is allowed to flow in either direction, depending on the pressure difference existing between the two locations. Surge margin at higher pressure ratios is significantly increased by the ported second-stage shroud.

Turbocharger compressor having ported second-stage shroud, and associated method

A multi-stage compressor and associated compressor housing and method are provided. The housing defines an aperture for receiving a compressor wheel for successively compressing a gas in first and second stages. First- and second-stage inlets are fluidly connected to the aperture in generally axial directions, and first- and second-stage volutes extend at least partially annularly therearound so that each volute is configured to receive gas flowing generally radially outward from the compressor wheel. In addition, first and second passages fluidly connect the first-stage volute to the second-stage inlet. Each passage extends from the first-stage volute to a position radially outward of the second-stage volute and therefrom to the second-stage inlet at an axial position opposite the second-stage volute from the first-stage volute. Thus, the gas can be received through the first-stage inlet, compressed by the wheel, circulated to the second-stage inlet via the first-stage volute and the passages, compressed again by the wheel, and delivered to the second-stage volute.

Multi-stage compressor and housing therefor

An EGR cooler comprises a cooling core having a plurality of passages for accommodating the flow of exhaust gas therethrough, an exhaust gas inlet chamber connected to the cooling core, for receiving exhaust gas from an internal combustion engine and passing the exhaust gas to the cooling core, and an exhaust gas outlet chamber separate from the exhaust gas inlet chamber and connected to the cooling core for receiving exhaust gas from the core. The cooler further includes means for permitting the controlled passage of exhaust gas from the exhaust gas inlet chamber to the exhaust gas outlet chamber without passing through the cooling core, said means being positioned upstream from the exhaust gas outlet chamber. Configured in this manner, the EGR cooler permits the mixing of cooled exhaust gas with uncooled exhaust to provide a desired exiting gas temperature that is below an exhaust gas dew point.

Exhaust gas recirculation cooler with bypass flow

Butterfly valves of this invention generally comprise a flapper element that is rotatably disposed within an annular bore of a valve housing. The valve may be configured to provide an improved degree of gas flow control sensitivity from a closed to a partially opened position through the use of projections that extend radially inwardly from the housing bore, are positioned at diametrically opposed positions within the bore, and that are specifically configured to provide a gradual increase in gas flow across the valve as the flapper is moved from a closed position to a partially opened position. The butterfly valve may be configured having further projections that extend radially inwardly a distance therein, that are positioned at diametrically opposed positions in the bore, and that include faces that are sized and shaped to cooperate with respective opposed surfaces of the flapper to seal off gas flow within the bore when the flapper is placed into a closed position. The butterfly valve may also be configured having a bushing that surrounds a shaft that is mounted to the flapper. The shaft extends through the housing and is coupled to an arm outside of the housing. The bushing and arm are configured having complementary surfaces to provide a seal therebetween that functions to minimize or eliminate the unwanted leakage of gas from the valve.
