A bubble trap is especially suitable for separating gas bubbles from liquid fuel supplied from a fuel tank in a spacecraft. The bubble trap includes a rotationally symmetrical collecting container forming a container wall, plural liquid guide vanes extending radially and longitudinally along the inside of the container wall, a perforated conical gas separator that tapers conically toward an outlet of the collecting container, and screens arranged between the gas separator and the outlet.

1. A bubble trap for separating gas bubbles from a liquid, comprising: a rotationally symmetrical container comprising a container wall that bounds a hollow space therein;an inlet communicating into said hollow space through said container;an outlet communicating out of said hollow space through said container;a plurality of guide vanes arranged extending radially inwardly inside said container wall;a gas separator comprising a perforated conical wall that is arranged proximate to said outlet, and that conically tapers in a direction toward said outlet, and that is perforated with through-holes; andat least one first screen arranged between said gas separator and said outlet. 2. The bubble trap according to claim 1, wherein said conical wall of said gas separator is shaped as a conical frustum, and wherein said gas separator further comprises a flat bottom floor at a narrower open end of said conical wall. 3. The bubble trap according to claim 2, wherein said flat bottom floor is perforated with more of said through-holes. 4. The bubble trap according to claim 2, wherein said at least one screen includes at least one first screen arranged adjacent to said conical wall and at least one second screen arranged adjacent to said flat bottom floor. 5. The bubble trap according to claim 4, wherein said screens are respectively arranged in or on respective openings through said container wall so that said screens cover said openings and form communication paths from said hollow space through said screens to said outlet. 6. The bubble trap according to claim 5, wherein said container wall includes a conical frustum shell and a flat bottom at a narrower tapered end of said conical frustum shell, wherein said openings include plural first openings distributed circumferentially about said conical frustum shell and a second opening in said flat bottom, and wherein said at least one first screen includes plural first screens respectively arranged in or on said first openings and one second screen arranged in or on said second opening. 7. The bubble trap according to claim 6, wherein said container further comprises a liquid collector arranged outside on said flat bottom to cover said second opening, and plural screen adapter covers arranged outside on said conical frustum shell respectively to cover said first openings, wherein said outlet communicates out through said liquid collector. 8. The bubble trap according to claim 7, further comprising connector pipes respectively connecting said screen adapter covers to said liquid collector outside of said container wall. 9. The bubble trap according to claim 1, further comprising an outlet pipe connected to and extending outwardly from said outlet, wherein said container further comprises a liquid collector arranged on said container wall, and wherein said outlet is provided on said liquid collector. 10. The bubble trap according to claim 1, wherein said gas separator is arranged and configured so as to form a tapering annular gap between said perforated conical wall of said gas separator and said container wall, and wherein a width of said gap increases in a direction in which a diameter of said perforated conical wall increases. 11. The bubble trap according to claim 1, wherein an upper rim portion of said conical wall of said gas separator has plural elongated slots therein distributed uniformly about a circumference thereof. 12. The bubble trap according to claim 11, wherein said upper rim portion of said conical wall of said gas separator with said elongated slots is not perforated with said through-holes, and said through-holes are uniformly distributed over a remainder of said conical wall other than said upper rim portion. 13. The bubble trap according to claim 11, wherein said slots have a width of about 1 mm, and said through-holes have a diameter of about 1 mm. 14. The bubble trap according to claim 1, further comprising an impingement baffle plate arranged in said container proximate to and transversely intersecting an axis of said inlet. 15. The bubble trap according to claim 1, wherein said container comprises a semi-spherical shell, a cylindrical shell and a conical frustum shell that are joined to one another to form said container wall, and wherein said inlet communicates through said semi-spherical shell, and wherein said conical frustum shell is opposite said semi-spherical shell with said cylindrical shell therebetween. 16. The bubble trap according to claim 1, wherein said guide vanes extend along longitudinal meridians on an inner surface of said container wall, and are joined together to form a cage structure by respective rings at upper and lower ends of said guide vanes, and wherein radially inner edges of said guide vanes bound an interior reservoir space within said hollow space inside said container. 17. The bubble trap according to claim 1, wherein said gas separator spans an entire sectional area of said hollow space in said container, so that all of the liquid flowing through said hollow space from said inlet to said outlet must flow through said gas separator before reaching said at least one screen. 18. A bubble trap for separating gas bubbles from a liquid, comprising: a rotationally symmetrical container comprising a container wall that bounds a hollow space therein;an inlet communicating into said hollow space through said container;an outlet communicating out of said hollow space through said container;a plurality of guide vanes arranged extending radially inwardly inside said container wall;a gas separator that is arranged proximate to said outlet, and that comprises a perforated conical frustum wall which conically tapers in a direction toward said outlet and a perforated flat bottom floor at a narrower open end of said conical frustum wall, wherein said conical frustum wall and said flat bottom floor are perforated with through-holes; andplural screens arranged between said gas separator and said outlet, including at least one first screen arranged adjacent to said conical frustum wall and at least one second screen arranged adjacent to said flat bottom floor, wherein said screens are respectively arranged in or on respective openings through said container wall so that said screens cover said openings and form communication paths from said hollow space through said screens to said outlet. 19. A combination of a bubble trap, a spacecraft fuel tank, a spacecraft rocket engine, a first fuel line connecting said fuel tank to said bubble trap, and a second fuel line connecting said bubble trap to said rocket engine, wherein said bubble trap is adapted to remove gas bubbles from fuel supplied from said fuel tank through said first fuel line, and wherein said bubble trap comprises: a rotationally symmetrical container comprising a container wall that bounds a hollow space therein;an inlet connected to said first fuel line and communicating into said hollow space through said container;an outlet communicating out of said hollow space through said container and connected to said second fuel line;a plurality of guide vanes arranged extending radially inwardly inside said container wall;a gas separator comprising a perforated conical wall that is arranged in an area proximate to said outlet, and that conically tapers in a direction toward said outlet, and that is perforated with through-holes; andat least one screen arranged between said gas separator and said outlet.
