ABSTRACT:
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.
