Title:
SLIP JOINT DUCT SYSTEM
Document Type and Number:
WIPO Patent Application WO2000079167
Kind Code:
A3
Abstract:
Various joints within a duct assembly to allow relative movement between portions of a fluid system which are interconnected by this duct assembly are disclosed. This duct assembly is particularly suited for interconnecting a rocket fuel tank (200) and rocket engine (100) of a space travel vehicle. In any case, this duct assembly (300) includes a pair of duct suctions (10, 20), each of which includes a gimbal (24, 44) on an end thereof. The opposite ends of these two duct sections are disposed in a telescopic arrangement with a slip joint (28, 46) therebetween to allow the duct sections (10, 20) to move at least generally axially relative to each other. This slip joint (28, 46) includes a pair of longitudinally spaced bushings (64, 66), between which are disposed a plurality of annular seals (60, 62). The bushings (64, 66) inhibit contact between the two duct sections (10, 20) by maintaining the same in spaced relation.
