APPLIANCE FOR JETTISONING CONDENSATE FROM FLYING VEHICLE FUEL TANK Russian patent published in 2008 - IPC B64D37/20 

FIELD: mechanics.

SUBSTANCE: appliance for jettisoning the fuel condensate incorporates a discharge funnel, a casing for vessel and telescoping tube device made up of a set of tubes linked to the tube locking device. Here, the outer tube device locking it relative to inner tube (4) is made as nut (8)screwed on the outer tube and at least, two blocks (10) arranged between the nut and outer tube, every block being provided with circular cam (14) supported by ring (15) set to move free on the nut inner surface. The blocks inner surface is made cylindrical (11), while their outer surfaces are made tapered (12, 13) and inclined from the circular cam to the block edges, and the nut is provided with a flange (16) interacting with upper tapered surfaces (12) of the blocks. Here, lower tapered surface (13) of the blocks, in an operating conditions, interacts with the outer tube adapter inner surfaces.

EFFECT: ease of operation.
