FUEL-TANK PRESSURISATION SYSTEM Russian patent published in 2008 - IPC F02K9/50 

FIELD: engines and pumps.

SUBSTANCE: invention relates to space engineering, particularly, to development and operation of jet engine plants of spaceships. The fuel-tank pressurisation system comprises high-pressure tanks containing fuel and oxidiser, shut-off valves arranged on the aforesaid pneumatic lines, throttling devices representing encased disks with a central throttling bore, as well gas pressure regulators. In compliance with the proposed invention, the aforesaid disks are made integral with the throttling device cylindrical casings. Note here that the grids and funnels are arranged on the casing end face sides for a smooth transition and coupling with the pneumatic lines. Note also that the disk both sides surfaces have equal-height extending thin-wall ribs arranged opposite to the like ribs arranged on appropriate grids. Note also here that the rib made on the disk surface and that arranged on the grid are located in the same plane. The proposed invention features also filtration elements arranged between the disk rib end faces and the grids, representing a screen made of high-quality rust-resisting material, and the throttling elements, being fitted, by means of funnels, into the pneumatic lines to extend to the gas pressure regulators.

EFFECT: higher efficiency and reliability of system operation.
