摘要： A throttle valve for a centrifugal compressor includes a body having a central passage and one or more diverter flow paths. The central passage is formed by an inner surface of the body, each diverter flow path has an inlet and an outlet, and the one or more diverter flow paths are configured to induce a swirl within a fluid flow through the central passage while a portion of the fluid flow passes through the one or more diverter flow paths. The throttle valve also includes at least one blade disposed within the central passage. The at least one blade is configured to direct the portion of the fluid flow to the inlets of the one or more diverter flow paths while the at least one blade is in a partially open position.

摘要： A compressor is provided with: an impeller a housing configured to rotatably house the impeller and having an intake passage for introducing a gas to the impeller from outside the housing, a scroll passage for guiding the gas having passed through the impeller to the outside, and a bypass passage connecting the intake passage and the scroll passage so as to bypass the impeller; and a bypass valve having a valve body disposed in the bypass passage and capable of opening and closing the bypass passage. The valve body is configured to, in a fully closed state, separate the bypass passage into an inlet-side passage having a communication port communicating with the scroll passage and an outlet-side passage communicating with the intake passage. An inlet-side passage wall surface which defines the inlet-side passage includes at least an upstream passage wall surface portion connected to an upstream end of the communication port in a cross-sectional view of the housing taken along an axis of the impeller. The upstream passage wall surface portion is configured such that an angle between the upstream passage wall surface portion and an upstream scroll wall surface of a scroll passage wall surface which defines the scroll passage connected to the upstream end is less than 90 degrees.

摘要： A return geometry fluidically connects a first and a second compressor stage of the turbocompressor. The return geometry has multiple partial helices that are evenly or unevenly distributed in the circumferential direction. The multiple partial helices extend at least in part in the circumferential direction. They form flow channels that extend at least in some sections, separately from each other, to fluidically connect the first and second compressor stages.
