Abstract

Изобретение касается устройства для поворота лопатки статора в турбинном агрегате. Устройство содержит пружину (15) угловой формы, которая расположена между утолщением (17) соединительной тяги (10), которая управляет положением лопатки статора, и осью (3) указанной лопатки таким образом, что ее край (18) отклоняется от поверхности (19) одного края соединительной тяги (10), и пластина (16) передвигает ось (3) в зазоре отверстия (21) соединительной тяги, устанавливая и поддерживая контакт между двумя плоскими гранями (12 и 13) таким образом, чтобы уменьшить различие в угловых положениях соединительной тяги и оси. Различие в угловых положениях этих элементов возникает за счет зазора в отверстии (21).
