摘要： A ratio of cross sectional area A of a scroll passage to a scroll radius R (A/R) can be increased without increasing the size of a turbine casing and with very simple construction. An exhaust turbine capacity can thus be increased, so that a variable-throat exhaust turbocharger in which the engine output can be increased results. The turbocharger has a nozzle throat area varying mechanism of which a nozzle assembly unit is composed. A plurality of nozzle vanes are supported rotatably by an annular nozzle mount and an annular nozzle plate is connected to the nozzle mount by a plurality of nozzle supports to sandwich the nozzle vanes. The nozzle plate is located in the scroll chamber by attaching the nozzle assembly unit to the turbine casing to allow the nozzle plate to form part of the inside sidewall face of the scroll chamber and a wall face of the annular flow passage.

摘要： The present invention provides a variable-throat exhaust turbocharger equipped with a variable-throat mechanism of which connection of constituent members can be achieved with a small number of man-hour and at low cost and which is stable in quality with firm connection of constituent members maintained under severe operating conditions. Among constituent members of the variable throat-area mechanism of the variable-throat exhaust turbocharger for varying the blade angle of a plurality of nozzle vanes supported rotatably by a members in a turbine casing, shaft members to be inserted and fixed in through-holes in a member with through-holes are produced by a method in which wear-resistant material is welded to form cladding of a certain thickness on the upper surface of a steel plate, said material being harder than the steel plate, and then crude shafts for forming drive pins are cut out from the clad plate.

摘要： A manufacturing method for manufacturing a component part for a variable capacity turbine, and the structure of a nozzle driving member, will simplify the structure of the component parts for the adjustable nozzle mechanism, the manufacturing work, which results in lowering the manufacturing count and cost as well as the number of component parts, and in lightening the weight of the variable capacity turbine. In order to manufacture the component parts for a radial-flow variable capacity turbine, in which actuating gas is forced to flow from a spiral scroll formed in a turbine casing to a turbine rotor in a radial direction through multiple nozzle vanes, of which the angle is adjustable by an adjustable nozzle mechanism, for rotating a turbine rotor, this manufacturing method has a column shaped connecting pin formed as a single structure with a plate member by pressing, or by precision molding by partially forcing the surface of the plate member to protrude in a column shape.
