Sealing system for fuel injection device of common rail diesel internal-combustion engine, has casing protruding from recess in partly assembled condition, rests on surface of components, and deformed such that surfaces contact each other

摘要

The system has component channels (13) penetrating through opposite surfaces (15) of components (11), where a medium is led through the channels at high pressure. A recess (17) increasing an inner diameter of the channels is integrated into one of the opposite surfaces in a region of the appropriate channel. A circular or tubular casing (18) is provided in the recess, protrudes from the recess in partly assembled condition, and rests on a surface (16) of another set of components (12). The casing is deformed when assembling such that the opposite surfaces (15, 16) contact each other.
