VGT ; VARIABLE GEOMETRY TURBOCHARGER

摘要

PURPOSE: A variable geometry turbocharger is provided to simplify a manufacturing process by removing of a guide, a guide pin, and a nozzle ring pin and save manufacturing cost. CONSTITUTION: A variable geometry turbocharger comprises a nozzle ring(10), a unison ring(20), a vane(40), a vane shaft, a vane arm, and an operating unit(50). The protrusion(12) of the nozzle ring is protruded toward one surface in a radial direction. The unison ring is placed in the protrusion on one surface of the nozzle ring. The vane is installed on the other surface of the nozzle ring. The vane shaft is connected to the vane and passes through the nozzle ring. The vane arm is connected to the vane and is rotatably coupled to the unison ring. The operating unit rotates the unison ring relatively to the nozzle ring.
