Abstract
Abstract A connecting conduit arrangement with several branch sections which lead to attachment points where hollow fasteners are provided. The arrangement includes a drain conduit connectible to injector-nozzle holders of internal combustion engines with fuel injection. A one-piece conduit is included in the arrangement having at least one branch section. The branch section is bent at an angle of about 180° in the vicinity of the attachment point to provide a bent branch section. A connecting part is also disclosed which is operatively associated with the hollow fastener belonging therewith.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
183 words
A connecting conduit arrangement for connecting a drain conduit with hollow attachment screws to the drains of fuel injection nozzle holders of an internal combustion engine, the arrangement comprising: a tube comprising a substantially straight section extending between two fuel injection nozzle holders, the straight section having U-shaped sections each formed of two opposed legs joined by a bight and extending at approximately 90° to the straight section, the U-shaped sections connecting the straight section to adjacent straight sections and extending to the drains of the nozzle holders with the bight portions of the U-shaped sections positioned adjacent the drains, the opposed legs of the U-shaped sections having opposed cut-outs through the walls thereof in alignment with the drains to establish communication therewith and through which is received one of the hollow attachment screws; a connecting part fitting over the opposed legs, the connecting part having having a hole therethrough aligned with the opposed cut-outs and a flat surface against which the head of the hollow attachment screw seals, whereby communication between the drain and conduit is established through the hollow attachment screw.
