ABSTRACT:
The object of the invention is to provide a nozzle ring for the exhaust-gas turbine of a turbocharger which, in addition to an improved service life, also guarantees a constant efficiency.
According to the invention, this is achieved in that an radial expansion gap (20) is formed between the turbine casing (2) and the nozzle ring (11), and at least one seal (22) is arranged in the expansion gap (20). To this end, an encircling groove (21) accommodating the seal (22) is formed in at least one of the fastening elements (16, 17) of the nozzle ring (11) or in at least one of the components (3, 4, 5) which surround the fastening elements (16, 17).
