    摘要： The invention relates to a fuel injection valve (1), particularly used as injector for fuel injection units of air compressed, self igniting internal combustion engines, comprises a nozzle body (2) with a valve seat surface (7) and a nozzle needle (3) interacting with the valve seat surface (7) as a sealing seat in order to control a fuel flow to an injection hole (15) located downstream of the sealing seat of the nozzle body (2). The injection hole (15) is rounded at an inflowing region (16). The injection hole (15) further comprises a tapering and a cutting edge (29) at an outer region of the hole (18). Thus high efficiency atomization of fuel close to the nozzle is possible.

    摘要： The invention relates to a fuel injection valve for internal combustion engines having a valve body (1) in which a blind hole (10) is formed, with at least one injection opening (7) proceeding from said blind hole (10). A longitudinally displaceable needle (5) is arranged in the valve body (1), with a valve sealing face (11) being formed at that end of said valve needle (5) which faces towards the blind hole (10), said valve sealing face (11) being formed from one or more conical faces, and the valve needle (5) interacting, by means of a body seat (9), with said valve sealing face (11) to control a fuel flow to the at least one injection opening (7). A needle tip (30) adjoins the valve sealing face (11), said needle tip (30) dipping into the blind hole (10) when the valve needle (5) bears against the body seat (9), the needle tip (30) being curved in a concave fashion directly adjacent to the valve sealing face (11).

    摘要： The invention relates to an injection valve (1), in particular for an internal combustion engine of a motor vehicle, comprising a valve housing (10) from which an inlet stub (14) having an inlet region (15) protrudes into a fluid inlet chamber (13) formed by the valve housing (10) together with a connection cap (12) that surrounds the valve housing (10) in the circumferential direction, wherein there is a flow path (18, 29) between the inlet stub (14) and the connection cap (12) as viewed in the radial direction, which flow path is closed by means of a sealing element (19, 30) that surrounds the inlet stub (14). According to the invention, the sealing element (19, 30) is in permanent sealing contact with the valve housing (10).

    摘要： The invention relates to a fuel injection device for injecting fuel into the combustion chamber of an internal combustion engine, comprising a housing (1) in which an injection valve member (3) is accommodated and can be moved back and forth in longitudinal direction, the end of which faces the combustion chamber and is in closed condition of the injection valve member (3) defining a blind-end bore (5), out of which in open condition of the injection valve member (3) fuel is injected into the combustion chamber. In order to improve the fuel injection device in terms of fuel mixture production quality and/or injection stream, the blind-end bore (5) has a diameter (D) of less than 0.8mm.
