Definitions
- the valve body 5 is formed in the area in which the valve needle 10 is guided with a cylindrical outer surface which tapers to the combustion chamber to approximately the level of the pressure chamber 18 to form a contact surface 44, the contact surface 44 in a radial plane to the bore 8 lies.
- the clamping nut 7 is essentially designed as a hollow cylinder and surrounds the valve body 5 and a part of the valve holding body 3, in particular in the area of the contact surface 30. At its end facing the combustion chamber, the clamping nut 7 has a collar on which a sealing surface 42 is formed. which comes to rest on the contact surface 44 and forms a first sealing connection between the clamping nut 7 and the housing 1.
