Definitions
- the present invention has'for its object a device in which the pivotal movement of the vanes is not produced simultaneously for all" the vanes but for only one half of the latter, either for example by the even or odd vanes. Tn first turning for example the even vanes until they are in their middle position, in then causing the odd vanes to entirely pivot and in achievin then as a third operation the pivoting of the even vanes, it will be pos- ⁇ sible to obtain the complete reversibility of the wheel while having the possibility of 5 sensibly decreasing the pitch of the vanes for the same evolvent ofthese latter in the circumferentialdirection.
- FIG. 1 is a vertical section made bythe axis of the turbine.
- Fig. 2 is a section made according tolme 2'2 of 1, and,
- Fig. 3 is a section made according to line 3--3 of the same figure.
- Fig. i shows a development of the positions of vanes.
- vanes are terminated by truncated parts engaged in a hub 'l'.
- the even vanes, 6 for example, carry on their truncated part 8 a bevel gear 9 next to the periphery of the hub 77 and the odd vanes 3 for example, carry, on their truncated part 22, a bevel gear or wheel near the middle of this hub.
- a hollow shaft 11 carries a ring 12 meshing with the gears or pinions 9 while a concentric shaft 13 carries a ring 14: meshing with the gears or pinions 10.
- a central shaft 15 is provided with two reverse threads 16 and lZ'respectively meshing with nuts 18 and 19 which are connected 8 and 22.
- the shaft lfi projects at the upper part as far as the middle of adiaring part 23 of the motor shaft 24:, the shaft 13 ending a little lower and the shaft 11 still lower.
- a motor 25 drives through gear wheels 26, 27 28, 29 a ring 30 with internal teeth which loosely revolves about the shaft 15. o
- the ring 30 can be coupled by means of an electro-magnet 31, with a disc or plate 32 connected with the shaft 15.
- the driving or controlling electric current is led to the motor and'to the electro-magnets 31, 33, 34 and 35 by -means of rings se-. the flaring part 23.
- said means comprising a central shaft placed on the axis of the said runner and provided with two reverse threads at the end located in the the conical seat of said'vanes and means for rotating-the said shaft.
- vanes of the other group to also pivot axially independently from the vanes of the first group, a truncated seatat the base of each vane, the hub of the saidwheel being provided with a conical bore, said truncated seat being adapted'to .fit into the said conical bore and to rotate in said bore, bevel gears on the truncated seat of the vanes of thefirst group, bevel gears on the truncated seat of the vanes of the second group, a first gear wheel adapted tomesh with the .bevel gears of the first group,
- a second gear wheel adapted to mesh with the bevel gears of the second grou a first hollow shaft, upon which -is mounte the first gear wheel, a second hollow shaft concentric to.
