  • Publication number: 20190113050
    Abstract: A compressor housing for a turbocharger includes an outer housing structure, an inner housing structure, and a rear housing structure. The outer housing structure includes a first tubular portion and a first radial portion extending radially outward of the first tubular portion. The inner housing structure includes a second tubular portion and a second radial portion extending radially outward of the second tubular portion. The rear housing structure includes an inner radial portion and an outer radial portion extending radially outward of the inner radial portion. The outer housing structure, the inner housing structure, and the rear housing structure are formed separately from each other and are coupled to each other. A recirculation cavity is defined radially between the first tubular portion and the second tubular portion. A volute is cooperatively formed by the first radial portion and the outer radial portion.

  • Patent number: 10077710
    Abstract: Wastegated turbochargers all use actuators to manipulate the wastegate valve which controls turbine wheel bypass of exhaust gas energy. The diaphragms in these actuators are susceptible to foreign material damage. This damage is minimized by the addition of a boot around the actuator shaft, preventing ingress of foreign materials and fluids which could be detrimental to actuator life.

  • Publication number: 20150023788
    Abstract: The propensity for turbocharger turbine divider wall to crack in the turbine housing is minimized by matching the mass of the divider wall more closely to the transient heat transfer between said divider wall and the exhaust gas flowing past it. This is achieved by providing said divider wall having a cross-sectional shape defined substantially by a Log2 curve.
