  • Patent number: 7543600
    Abstract: A system for mixing a first gas flow and a second gas flow includes a conduit defined by a wall for communicating the first gas flow therethrough, an inlet passing through the wall of the conduit for introducing the second gas flow into the conduit, and a valve body disposed within the conduit, the valve body being displaceable in a longitudinal direction with respect to the conduit at the inlet. The conduit includes a bend downstream of the body with respect to a direction of the mixed gas flow. A holder is operably connected at a first end thereof to a downstream end of the valve body, the holder passing through a bore in the wall of the conduit at the bend. An actuator is operably connected to a second end of the holder, the actuator causing, via the holder, the valve body to be displaced in the longitudinal direction.

  • Patent number: 7261096
    Abstract: A system for controlling the mixture of an air flow and an exhaust gas flow in an engine is disclosed generally comprising an air conduit for the inlet air, which has an exhaust gas inlet passing through the wall thereof for introducing recirculating exhaust gas into the conduit, and a sleeve having an inlet end through which air enters the sleeve and an outlet end through which air exits the sleeve into the conduit, where the sleeve is movable along the conduit to vary the extent to which the outlet end thereof occludes the exhaust gas inlet, thereby regulating the introduction of exhaust gas into the air conduit, which in some embodiments, is completely closed off. In some embodiments, the outlet end of the sleeve is reduced, and certain embodiments include a streamlined body to regulate the air exiting the sleeve.
