摘要： The invention relates to a fuel injection valve for fuel injection systems of internal combustion engines, comprising a valve closing body (4) that is functionally linked with a valve needle (3) and that interacts with a valve face (6) arranged in a recess of a valve seat body (5) to give a sealing seat, and at least one injection opening (7) arranged in the valve seat body (5). The recess of the valve seat body (5) defines a second surface (36) between the valve face (6) and the injection opening (7) which surface includes a more acute angle (β) with the median axis (37) of the fuel injection valve (1) than the valve face (6). A closing body projection (35) disposed on the down-stream end of the valve closing body (4) has a peripheral surface (39) that forms an obtuse angle with the adjoining contour of the valve closing body (4).

摘要： The invention relates to a fuel-injection valve (1), in particular for fuel-injection systems of internal combustion engines. Said valve comprises an actuator (27), a valve needle (3), operated by said actuator (27), for actuating a valve closing body (4), which forms a seal seat with a valve seat surface (6) and a swirl device (15), which has at least one swirl channel (18) that is traversed by fuel with a tangential component in relation to a longitudinal axis (26) of the fuel-injection valve (1). The axial position of a bypass disc (17) that interacts with a valve needle (3) determines a cross-section of at least one bypass channel (19), which bypasses the swirl channel(s) (18) without a tangential component.

摘要： The invention relates to a fuel injection valve (1), especially an injection valve for injection systems of internal combustion engines. The inventive fuel injection valve comprises a piezoelectric or magnetostrictive actuator (32) and a valve closing element (11) that is actuated by means of a valve needle (10) and that interacts with a valve face (12) to seal the valve. To this end, the actuator contacts a support element (20) at a first front end (33) which support element is provided with at least one recess (24a, 24b, 24c) through which at least one section (25a, 25b, 26c) of an actuator cylinder (26) projects. The actuator cylinder (26) acts upon the valve needle (10) at a first end (27) and at a second end (29) encircles the actuator (32) at a second front end (34) of the actuator (32) that faces away from the first front end (33) of the actuator (32).

摘要： A fuel injection valve (1), especially a fuel injection valve for fuel injection systems of internal combustion engines, has a piezoelectric or magnetostrictive actuator (8), a valve needle (15) which can be actuated by the actuator (8) by means of a hydraulic temperature compensation device, and a valve closing body (28) which is actuated by the valve needle (15), and which interacts with a valve seat surface (14) to form a sealed seat. Said temperature compensation device comprises a needle carrier sleeve (31) which encompasses a valve needle collar (32) of the valve needle (15) and encloses said valve needle (15) in sections with a needle carrier collar (32). The needle carrier sleeve (31) also encloses a temperature compensation area (27) with the valve needle (15), said temperature compensation area (27) being connected to a fuel inlet (4) by a directional valve (29) so that said temperature compensation area (27) can be filled with fuel.
