ROCKET ACCELERATING ENGINE CRYOGENIC COMPONENT DRAIN DEVICE Russian patent published in 2012 - IPC B64G1/40 

FIELD: transport.

SUBSTANCE: invention relates to aerospace engineering, particularly, to cryogenic component draining from cryogenic tank of rocket accelerating unit. Said drainage consists of drain valve arranged on cryogenic tank and drain pipeline. Drain pipeline at outlet of accelerating unit is secured to its structural element including guide support and thermal bridge. Darin pipeline incorporates additionally a spherical sleeve arranged inside guide support. Drain pipeline central section is secured on cryogenic tank upper bottom by adjustable bracket. Said adjustable bracket comprises support with threaded end, two half-holders embracing drain pipeline and arranged on said threaded tip, adjusting washer arranged between support and bottom half-holder, and spherical inserts arranged on inner surfaces of top and bottom half-holders. Curved branch pipes are fitted from drain valve into drain pipeline to make U-shape section in drain pipeline. Angular displacement compensator is arranged at drain pipeline central section to compensate, along with bracket and adjustable bracket, mounting and working displacements.

EFFECT: higher reliability.
