CONNECTION OF COMPONENTS, CARRYING HIGH-PRESSURE MEDIUM, OF AN INJECTION DEVICE FOR INTERNAL COMBUSTION ENGINES

Document Type and Number:

WIPO Patent Application WO/2013/082640

Kind Code:

A3

Abstract:

The invention relates to a connection of components (1, 2), carrying high-pressure medium, of an injection device for internal combustion engines, comprising a first component (1) and a second component (2), the surfaces of which are hardened and which have sealing surfaces (4, 5) facing one another, wherein the sealing surfaces (4, 5) on the components facing one another interact with sealing surfaces on an intermediate piece (3) having a passage hole (7) arranged between the first and second components, said intermediate piece having a lower hardness than the sealing surfaces (4, 5) on the first and second components (1, 2), wherein one respective sealing surface of two sealing surfaces interacting with one another has a sealing edge (6).
