SYSTEM OF SEALED CONNECTION BETWEEN TUBULAR SECTIONS, NAMELY FOR SEALED CONNECTION OF TUBE FOR SUPPLY OF FUEL GAS UNDER HIGH PRESSURE WITH PRESSURE REDUCING VALVE IN AUTOMOBILE INTERNAL COMBUSTION ENGINES Russian patent published in 2012 - IPC F02M21/02 F16L37/14 

FIELD: engines and pumps.

SUBSTANCE: system includes connection socket devices which are made on one and the other of the above tubular sections with possibility of coaxial engagement with each other, gas-proof sealing device located between tubular sections; axial fixing device located between connection socket devices in order to retain one of the tubular sections relative to the other tubular section in direction of mutual axial connection. System also includes removable locking devices located between sections for rigid attachment of tubular sections to each other in the pre-selected relative position. Devices for attaching the sections in relative orientation are independent of axial fixing device.

EFFECT: invention provides gas-proof sealing in the state when tubular sections are freely oriented relative to each other without any effect of locking devices.
