FIELD: machine building.
SUBSTANCE: system and method of work fluid extraction from internal volume of turbine machine contains blades cartridge with ring guide, and multiple blade devices, each of them has flange, blade element, installed on flange, and shank installed on the ring guide. Between the flange and ring guide the first ring cavity is made, and between the blade shank, the ring guide and the blades cartridge the second ring cavity is made. Between edge of the blade flange and the blades cartridge the ring clearance is made with the possibility of the fluid extraction to the first ring cavity. In the ring guide an inlet hole is made, it connects the first and the second ring cavities. Another group invention relates to the turbine machine containing rotating shaft and above described system of the work fluid extraction. During the work fluid extraction from the internal volume of the turbine machine the above extraction system is used.
EFFECT: group of inventions simplifies the system of work fluid extraction from the turbine machine.
