CLOSING ASSEMBLY FOR COVERING REMAINING INTERMEDIATE SPACE BETWEEN FIRST AND LAST BLADE OF BLADE ROW, WHICH IS INSTALLED IN CIRCUMFERENTIAL GROOVE OF BLADE MACHINE, AND APPROPRIATE BLADE MACHINE Russian patent published in 2010 - IPC F01D5/32 

FIELD: engines and pumps.

SUBSTANCE: closing assembly for covering the space between the first and the second blades installed in circumferential groove of blade machine consists at least of two side parts and at least one pin-shaped fixing element. At least one of side parts is intended for being engaged with projection of circumferential groove, which forms the backed-off space. Both side parts are attached to each other through the guide made in the form of swallow nest, or each side part is attached through the appropriate guide in the form of swallow nest with intermediate part located between them. The other invention of the group refers to blade machine with the rotor having at least one circumferential groove which has backed-off spaces and rotating blades fixed in it. The remaining intermediate space between the first and the last blade installed in circumferential groove is fully covered with the closing assembly made as described above.

EFFECT: inventions allow increasing reliability of connection of the closing assembly owing to eliminating unintentional outlet of fixing element.
