    Abstract: The invention relates to a fuel injection valve for fuel injection systems of internal combustion engines. The fuel injection valve comprises an electromagnetic actuating element with a solenoid (1), an inner pole (2) and with an outer magnetic circuit component (5), and comprises a moving valve closing body (19), which interacts with a valve seat (16) assigned to a valve seat body (15). The valve seat body (15) and the inner pole (2) are placed inside an inner opening (11) of a thin-walled valve sleeve (6), and the solenoid (1) and the outer magnetic circuit component (5) are placed on the outer periphery of the valve sleeve (6). The valve sleeve (6) comprises an outside section (12) and comprises a bottom section (13) at the downstream end of the valve sleeve. This bottom section extends in a manner that is largely perpendicular to the otherwise axial extension of the valve sleeve (6) at an axial distance to a spraying perforated disk (21). A cavity (60) is formed between the fuel spraying perforated disk (21) and the bottom section (13) of the valve sleeve (6). This cavity exerts a capillary action in a radial outward direction onto the fuel exiting from the at least discharge opening (27).

    Abstract: In an electromagnetic type fuel injection valve for internal combustion engines, a valve-driving electromagnetic coil bobbin (15) is made of a synthetic resin containing a filler having good thermal conductivity. The electromagnetic coil includes two kinds of coils (12, 13), different in characteristics from each other, that are axially-separately wound on one bobbin (15). One coil (12) is wound on the bobbin (15) such that it is closer to a movable element (19) than the other coil (13), and the outer diameter of the bobbin in the region where the other coil (13) is wound is smaller than the outer diameter of the bobbin in the region where one coil (12) is wound. Further, the inner diameter of the bobbin in the region where one coil (12) is wound has a level difference to form an annular space in which a seal ring (18) is disposed. The two kinds of coils (12, 13) are connected to a power supply and a switching element through a three-terminal connector.

    Abstract: A fuel delivery injector for a spark-ignition internal combustion engine. The delivery injector forms part of a device (10) which provides a combined fuel injection and ignition means for the engine. The fuel delivery injector comprises means defining a flow path (28) for delivery of a fuel entrained in a gas to a combustion chamber of the engine. The flow path (28) has a delivery port (30) through which the fuel is delivered into the combustion chamber as a spray of fuel droplets and vapour, the delivery port (30) being defined between a valve seat (31) and a valve member (23) movable with respect to the valve seat (31) for opening and closing the delivery port (30). The delivery injector is configured to influence the trajectory of the fuel spray, whereby smaller fuel droplets and vapour in the fuel spray are caused to flow towards a spark gap (49) in close proximity to the downstream end of the delivery port (30) and whereby larger fuel droplets are not so caused to flow towards the spark gap (49). The trajectory of the fuel spray may be so influenced by the presence of a flow control means or the configuration of the delivery port. Where a flow control means is utilized, it may comprise a flow control projection (41) which is provided on the valve member (23) and which extends outwardly therefrom beyond the delivery port (30). Where the device (10) provides a combined fuel injector and ignition means, the device (10) is provided with a primary electrode (48) which cooperates with a secondary electrode (47) to define the spark gap (49). The flow control projection (41) is utilized to define the primary electrode (48). The device (10) providing the combined fuel injection and ignition means is also described and claimed.
