Patent ID: 7891586

Claim:
A fuel injection valve ( 4 ; 200 ) for the intermittent injection of fuel into the combustion chamber of an internal combustion engine, having an elongate housing ( 6 ), which comprises a housing body ( 10 ; 214 ) and a nozzle body ( 14 ; 132 ; 206 ) with an injection valve seat ( 54 ), a high-pressure chamber ( 52 ; 152 ; 220 ), which is arranged in the housing and which is connected to a high-pressure fuel inlet ( 20 ) and to the injection valve seat ( 54 ), an injection valve member ( 30 ; 138 ; 204 ), which is arranged so that it is longitudinally adjustable in the housing ( 6 ) and which interacts with the injection valve seat ( 54 ), and a closing spring ( 60 ), which is supported on the one hand on the injection valve member ( 30 ; 138 ; 204 ) and exerts a closing force on that element, directed towards the injection valve seat ( 54 ), and which on the other hand is supported at least via a guide sleeve ( 58 ; 143 ) and a control member ( 70 ; 230 ) on a face ( 11 ) fixed to the housing and in so doing presses the control member ( 70 ; 230 ) against the face ( 11 ), sealing off the high pressure chamber ( 52 ; 152 ; 220 ), the control member ( 70 ; 230 ) having a control passage ( 114 ), which is arranged eccentrically offset in relation to a housing axis ( 8 ), defining a central longitudinal axis of the housing ( 6 ), and which for the purpose of controlling the opening and closing movement of the injection valve member ( 30 ; 138 ; 204 ) can be opened and closed by an actuator assembly ( 26 ), and means being provided for fixing the eccentric circumferential position of the control passage ( 114 ) of ′the control member ( 70 ; 230 ) on an actuator axis ( 8 ′) shared with the actuator assembly ( 26 ) and eccentrically offset in relation to the housing axis ( 8 ).
