Abstract
An aspirator for an evacuation assembly includes a duct defining a flow axis with an upstream portion and a downstream portion, a vane spanning the upstream portion of the duct, and a nozzle. The nozzle has an outlet, is supported by the vane, and is positioned within the upstream portion of the duct. The outlet is laterally offset from the flow axis and is axially overlapped by the vane to limit resistance to a primary gas flow entering the duct through the outlet of the nozzle. Evacuation assemblies are also described.

An aspirator for an evacuation assembly, comprising:
- a duct defining a flow axis with an upstream portion and a downstream portion;
- a vane spanning the upstream portion of the duct, the vane having a u-shaped profile including a base segment and first and second edge segments, wherein the first edge segment extends laterally from the base segment and towards an inlet of the duct and is oriented obliquely toward the flow axis and the second edge segment extends laterally from the base segment on a side of the flow axis opposite the first edge segment and is oriented obliquely toward the flow axis;
- and
- a nozzle with an outlet supported by the vane and positioned within the upstream portion of the duct, wherein the outlet of the nozzle is laterally offset from the flow axis.
