The stator vane of distribution of the hot gases of a turbo-machine.

The invention relates to a vane of a turbomachine, comprising blades (1) and lower bases (3) and upper (4) permitting the fixing of the blades on a structure of the turbomachine, each blade comprising longitudinal cavities and each base having transverse cavities adapted to the circulation of a cooling fluid, the blades having coolant intake ports external to the cavities and external orifices of exhaust fluid out of cavities. According to the invention: A) the number of orifices (38, 39, 40, 41, 42, 43, 44) inlet is equal to the number of longitudinal cavities; B) the longitudinal and transverse recesses are associated in pairs (22-5; 14-6; 7-15; 23-8; 9-24; 16-10; 25-11), the longitudinal cavity of a pair having a end section in communication with the transverse recess of the pair: C) the intake ports communicate directly with the cavity (22, 14, 7, 23, 9, 16, 25). One application is the realization of a high efficiency gas turbine.
