FIELD: engines and pumps.
SUBSTANCE: proposed assembly comprises deflecting grid, and outer and inner strong shell rings of movable casing. Said outer and inner strong shell rings are jointed by carriages. The latter move on axial guide rods secured on front and rear stationary cases. Inner shell ring rear flanges are jointed with additional inner rods. Axial hollow guide rods allow inner rods to telescope therein. Inner rod rear stems are secured on rear flanges of movable casing inner strong shell ring. Inner rod length-to-outer rod length ratio makes 1.1…1.5 while outer shell diameter to-outer shell length ratio makes 3…5.
EFFECT: smaller overall dimensions and weight.
