Abstract: In one embodiment, a centrifugal impeller is described having a front side with airfoils and a back side. A conduit may be formed between the front side and the back side, or any other side, and may convey pressurized working fluid between the two. The conduit may pass relatively high pressure working fluid between any two locations such as from the front side to the back side. The conduit may include an aperture located on the front side and an aperture located on the back side. Any number of conduits may be defined within the centrifugal impeller. Apertures located on the front side of the impeller may be formed in any suitable place, such as a hub of the impeller or an airfoil surface, to set forth just two non-limiting examples.

Abstract translation: 在一个实施例中，描述了具有前翼面和后侧的离心式叶轮。 可以在前侧和后侧或任何其它侧面之间形成导管，并且可以在两者之间输送加压的工作流体。 管道可以在任何两个位置之间通过相对高压的工作流体，例如从前侧到后侧。 导管可以包括位于前侧的孔和位于背侧的孔。 任何数量的导管可以在离心式叶轮内限定。 位于叶轮前侧的孔可以形成在任何合适的位置，例如叶轮的轮毂或翼型表面，仅列出两个非限制性实例。
