Abstract
1. Роторная машина, в которой ! предусмотрены первый кожух и второй кожух, образованные путем разделения, по существу, цилиндрического кожуха, заключающего в своем внутреннем пространстве роторный вал с установленными на нем роторными лопатками, на два кожуха, по существу, посередине осевой линии роторного вала, ! при этом у отверстий первого кожуха и второго кожуха выполнены первый соединительный фланец и второй соединительный фланец, соответственно, ! причем также имеется третий соединительный фланец, заключающийся внутри указанного кожуха, этот третий соединительный фланец расположен, по существу, посередине осевой линии, по существу, цилиндрического лопастного венца, удерживающего статорные лопатки и окружающего роторный вал, и удерживает собой указанный лопаточный венец, ! при этом первый кожух, второй кожух и лопаточный венец собраны друг с другом с размещением указанного третьего соединительного фланца между первым и вторым соединительными фланцами. ! 2. Машина по п.1, в которой ! лопаточный венец удерживается относительно третьего соединительного фланца, по существу, конусообразным соединительным элементом, ! при этом внутренняя периферическая поверхность этого соединительного элемента со стороны лопаточного венца выдается от стороны высокого давления к стороне низкого давления в рабочей текучей среде, протекающей между роторными и статорными лопатками. ! 3. Машина по п.1, в которой внешняя периферическая часть третьего соединительного фланца окружена первым и вторым соединительными фланцами. ! 4. Машина по п.1, в которой ! снаружи кожуха предусмотрен резервуар высокого давления, заключающий в� 1. Rotary machine in which! a first casing and a second casing are provided, formed by dividing the substantially cylindrical casing enclosing in its interior the rotor shaft with the rotor blades mounted thereon into two casings substantially in the middle of the centerline of the rotor shaft,! the first connecting flange and the second connecting flange are formed at the openings of the first casing and the second casing, respectively,! and there is also a third connecting flange, contained within the specified housing, this third connecting flange is located essentially in the middle of the centerline of the substantially cylindrical vane ring, holding the stator blades and surrounding the rotor shaft, and retains the specified vane ring,! wherein the first casing, the second casing and the blade ring are assembled with each other with the placement of the specified third connecting flange between the first and second connecting flanges. ! 2. The machine according to claim 1, in which! the blade ring is held against the third connecting flange by a substantially tapered connecting element,! wherein the inner peripheral surface of this connecting element on the side of the blade row projects from the high-pressure side to the low-pressure side in the working fluid flowing between the rotor and stator blades. ! 3. The machine of claim 1, wherein the outer peripheral portion of the third connecting flange is surrounded by the first and second connecting flanges. ! 4. The machine according to claim 1, in which! a pressure vessel is provided outside the casing, containing the
