[0045] Thepump2,heatexchanger3,generator5and condenser 6 will be not further described herein as they are of known type. [0046] Advantageously,theexpansionturbine4isofthe one-stageormultistageradial-out?owtype,i.e.itconsistsof one or more radial-out?ow expansion stages, or at least one radial-out?ow stage and of at least one axial stage. In other words,theworking?uid?ow entersturbine4alonganaxial direction in a radially more internal region of turbine 4 and ?ows out in an expanded condition along a radial or axial direction in a radially more external region of the turbine 4 itself.During theway between entry and exitthe ?ow moves away, while expanding, from the rotation axis “X-X” of the turbine4. [0047] A preferredbutnon-limitingembodimentofthe radial-out?ow turbine isshown inFIGS. 2 and 3.This turbine 4 comprises a ?xed box 7 formed with a front box half of circularshapeandarearboxhalf9joinedtogetherbybolts10 (FIG.3).A sleeve11emergesincantileveredfashionfromthe rearbox half9. [0048] Intheinnervolumedelimitedbythefront8andrear 9 box halves a rotor ishoused 12 which isrigidly constrained to a shaft 13 in turn rotatably supported in sleeve 11 by means of bearings 14 so that itis free to rotate around a rotation axis “X-X”. [0052] Insideturbine1,theworking?uid?owenteringthe axial inlet 15 is deviated by a baf?e 25 having a convex circular shape, which is ?xedly mounted on box 7 in front of rotor17andisdisposedcoaxialwiththerotationaxis“X-X”, theconvexitythereoffacingtheaxialinlet15andthein?ow ing ?ow. Baf?e 25 radially extends starting from the rotation axis“X-X” untilthe?rstseriesofstatorblades24a. The stator bladesofthe?rstseries2411areintegratedintotheperipheral portion ofbaf?e 25 and have an end mounted on the inner face 23ofthefrontboxhalf8.Ingreaterdetail,baf?e25isde?ned by a convex thin plate having a radial symmetry with a con vex/concavecentralportion25atheconvexityofwhichfaces the front box half 8 and the axial inlet 15 and a radially outermostportion25bthatisannularandconcave/convexand the concavity of which faces the front box half 8. The front boxhalf8andtheradiallyoutermostportion25bofbaf?e25 con?ne a diverging duct guiding the working ?uid to the ?rst stage (rotor blades of the ?rst series 2211 and stator blades of the ?rst series 24a) of turbine 4. [0053] Thefrontface18oftherotordisc8andface23of the front box half 8 carrying the stator blades 24a, 24b, 24c diverge from each other on moving away from the rotation axis (X-X), starting from said ?rst stage, and the radially outermost blades have a blade height greater than that of the radiallyinnermostblades.

A compensation chamber 21 is con?ned between the rear face 19 oftherotordisc 17 and therearbox half9. [0051] Thefrontface18oftherotordisc17carriesthree series of rotor blades 22a, 22b, 220. Each series comprises a pluralityof?atrotorbladesdisposedaron therotationdisc “X-X”. The rotorblades ofthe second series 22b are disposed at a radially external position to the rotor blades of the ?rst series 2211 and the rotor blades of the third series 220 are disposed at a position radially external to the rotor blades of the second series 22b. Three series of stator blades 24a, 24b, 240 are mounted on the inner face 23 turned towards rotor 17 ofthefrontboxhalf8.Eachseriescomprisesapluralityof?at stator blades disposed around the rotation axis “X-X”. The stator blades of the ?rst series 2411 are disposed at a position radiallyinternaltotherotorbladesofthe?rstseries22a.
