摘要： A centrifugal compressor for compressing a fluid comprises a compressor wheel having a plurality of circumferentially spaced blades, and a compressor housing in which the compressor wheel is mounted. The compressor housing includes an inlet duct through which the fluid enters in an axial direction and is led by the inlet duct into the compressor wheel, and a wheel shroud located radially adjacent the tips of the blades. A bleed port is defined in the wheel shroud at a location intermediate the leading and trailing edges of the blades for bleeding off a bleed portion of the fluid being compressed by the compressor wheel. A converging injection nozzle is defined in the duct wall upstream of the leading edges of the blades for injecting the bleed portion of the fluid back into the main fluid flow stream approaching the compressor wheel.

摘要： A housing is disclosed for a compressor having a duct defining a main gas flow axis and blades that draw a fluid through the duct. The blades impart to the fluid a momentum along a main gas flow direction and a swirl. The housing includes a volute configured to extend substantially circumferentially around and fluidly communicate with the duct (at a first location). The volute may be configured to direct a fluid portion flowing thereinto from the duct to have a velocity with a component in a first circumferential direction generally aligned with the swirl. The housing may also include at least one conduit, such as a pipe, in fluid communication with the first volute. The conduit may be configured to redirect the fluid portion to have a velocity with a first component along the main gas flow axis in a direction opposite the main gas flow direction and a second component in a second circumferential direction opposite to the first circumferential direction.

摘要： A housing is incorporated as part of a compressor having blades that impart to a fluid a momentum along a main gas flow direction and a swirl. The housing includes a channel that has at least one channel wall and defines an axis substantially aligned with the main gas flow direction. The channel is configured to duct at least some of the fluid. The channel wall defines an internal cavity that extends axially within the channel wall. A bleed passage connects and provides fluid communication between the channel and the cavity. The channel wall defines a plurality of injection passages providing fluid communication between the cavity and the channel at a location spaced in a direction opposite the main gas flow direction from both the bleed passage and the blades. The injection passages have a portion configured to direct fluid from the cavity into the channel with a component along the main gas flow direction and a component opposed to the swirl.
