Abstract: A turbocharger (1) including a twin scroll turbine and a valve assembly (40, 140) disposed in the exhaust gas inlet (24, 124) that is configured to control the flow exhaust gas through the turbine. The valve assembly (40, 140) includes two rotary valves (60, 160, 80, 180) actuated by a common valve shaft (44, 144). One of the valves (60, 180) may control exhaust gas flow to a volute or between volutes, and the other (80, 160) may control wastegate exhaust gas flow. The valve shaft (44, 144) is driven by an actuator to rotate about the valve shaft rotational axis (46, 146) such that the first valve (60, 160) and the second valve (80, 180) can each be selectively moved between a closed position and an open position, and the time sequence order of opening of the first valve (60, 160) and the second valve (80, 180) is selectable.

Abstract: A product is disclosed for recovering heat and may include a housing with two flow paths defined through the housing. A number of tube assemblies may be disposed in the housing. The tube assemblies may comprise an inner tube and an outer tube with a space defined between the inner tube and the outer tube. One flow path may be defined through the inner tubes, and the other flow path may be defined outside the outer tubes. A phase change material may be disposed in the spaces of the tube assemblies. The phase change material may change phases when exposed to a temperature change.
