Claims (3)

1. Многоступенчатый турбокомпрессор радиальной конструкции стаканного типа с противоположным направлением вращения, в котором за каждым расположенным в корпусе рабочим колесом следует диффузор, за которым расположен интегрированный большей частью во внешнем корпусе коллектор с тангенциальным выходным патрубком, отличающийся тем, что турбокомпрессор снабжен внутренним корпусом (7), который содержит расположенные в нем три рабочие колеса (4 - 6), за каждым из которых расположен лежащий в радиальным направлении отходящего потока безлопаточный диффузорный отрезок (14 - 16) и после колена (17, 18) в диффузоре установлены возвратные лопатки (19, 20), причем диаметр рабочих колес сильно уменьшен и соотношение диаметра безлопаточного диффузорного отрезка (14 - 16) к диаметру рабочего колеса (4 - 6) достигает величины DRR/D, ≥ 1,6 (индекс RR означает кольцевое пространство, и 2 - выходное рабочее колесо).1. A multistage turbocharger of a radial design of a glass type with an opposite direction of rotation, in which each impeller located in the housing is followed by a diffuser, followed by a collector with a tangential output nozzle integrated mostly in the external housing, characterized in that the turbocharger is equipped with an internal housing (7 ), which contains three impellers (4 - 6) located in it, behind each of which there is a free path lying in the radial direction of the outgoing flow the main diffuser segment (14 - 16) and after the knee (17, 18), return vanes (19, 20) are installed in the diffuser, and the diameter of the impellers is greatly reduced and the ratio of the diameter of the bladeless diffuser segment (14 - 16) to the diameter of the impeller (4 - 6) reaches a value of D RR / D, ≥ 1.6 (the index RR means the annular space, and 2 - the output impeller). 2. Многоступенчатый турбокомпрессор по п.1, отличающийся тем, что в последней ступени за безлопаточным диффузорным отрезком (16) следует снабженный лопатками отрезок (21), который расположен на большем диаметре, чем колено (18) соседней ступени. 2. A multistage turbocharger according to claim 1, characterized in that in the last stage, the bladeless diffuser segment (16) is followed by a segment (21) equipped with blades, which is located on a larger diameter than the elbow (18) of the adjacent stage. 3. Многоступенчатый турбокомпрессор по п.1, отличающийся тем, что основание (10) соединено с внутренним корпусом (7) с помощью проходящего через область снабженного лопатками отрезка (21) последней ступени болтового соединения (11). 3. A multistage turbocharger according to claim 1, characterized in that the base (10) is connected to the inner casing (7) by means of a segment (21) of the last stage of the bolt connection (11) passing through the region provided with vanes.
