Sealing means and a retaining element for a fuel-injection valve

Abstract

A sealing element (2) for a fuel injector (1) insertable into a receiving bore (3) of a cylinder head (4) of an internal combustion engine for direct injection of fuel into a combustion chamber (7) of the internal combustion engine has a sealing element (17) surrounding a nozzle body (5) of the fuel injector (1) peripherally. The sealing element (2) includes a base body (15) having an axial recess (16) through which the nozzle body (5) extends. The base body (15) also has an annular recess (18) which communicates with the recess (16) and into which the sealing element (17) is introduced. At a first contact face (51), the base body (15) is in at least indirect contact with an end face (58) of the fuel injector (1), and at a second contact face (57) opposite the first contact face (51), the base body (15) is at least in indirect contact with the step (11) of the receiving bore (3).
