Abstract (en)

[origin: DE19753162A1] The invention relates to a fuel injection valve for internal combustion engines, comprising a valve member (8) guided in an axially gliding manner in a bore (7) of a valve body (1). At its end facing the combustion chamber said valve member has a valve sealing surface (11) with which it cooperates with a valve seat surface (13) at the level of the valve body (1) so as to control an injection cross-section. The invention further provides for a stroke stop surface (37) which is fixed in relation to the valve body (1) and against which the valve member (8) comes to rest with a contact surface (41) after completing a maximum opening stroke directed towards the outside. The stroke stop surface (37) is positioned on a face of an axially divided stroke stop ring (35), which is enclosed by a support ring (33). The invention also provides for a valve spring (27) which impinges upon the valve member (8) in the direction of closure and rests in a fixed manner against the valve body (1) via a spacer ring (31) and an intermediate member. The support ring (33) enclosing the stroke stop ring (35) is mounted in a fixed manner in relation to the valve body (1) and is in constant contact with the spacer ring (31).
