Abstract: This invention relates generally fluid mixer assembly and more particularly to an exhaust gas recirculation (EGR) mixer comprising an inlet conduit, an exhaust conduit, and a shielded conduit. The shielded conduit is partially disposed in the inlet conduit and has a fluid diverting portion and fluid passing portion. The fluid diverting portion diverts intake air into a first fluid stream and a second fluid stream. Exhaust gas is passed through fluid passing portion and is mixed with the first fluid stream and second fluid stream generally at a point downstream of the shielded conduit.

Abstract: An endless track assembly comprises a pair of laterally spaced link assemblies each having a plurality of articulated links. Each pair of interconnected links is mounted on the end of a pin having a torsional track bushing mounted thereon. The torsional track bushing includes a metallic sleeve spaced longitudinally from one of the links and an elastomeric-based bushing secured between the metallic sleeve and such link for permitting relative torsional movements therebetween. The elastomeric-based bushing may constitute an annular member entirely composed of an elastomer, an elastomeric member secured on a metallic ring, or a plurality of elastomeric discs interleaved between a plurality of metallic discs.
