<p>A fluid injection device for an internal combustion engine. The fluid injection device has been devised particularly for fuel injection. The fluid injection device forms part of a device (10) which provides a combined injection and ignition means for the engine. The injection device comprises a body (33) having a fluid flow path (39) along which fluid can be conveyed to a delivery port (37) defined between a valve seat (61) and a valve member (63) movable with respect to the valve seat (61) for opening and closing the delivery port (37). An electromagnetic means (83) is provided for operating the valve member (63) to effect opening of the delivery port (37). The electromagnetic means (83) includes a solenoid armature (87) and a solenoid coil (85), the solenoid armature (87) being operatively connected to the valve member (63). A shroud (109) is disposed about the solenoid armature (87) for guidingly supporting the solenoid armature (87) upon movement thereof as the valve member (63) moves with respect to the valve seat (61). The device (10) is typically constructed in two portions being a first portions (31) and a second portion 32 which can be detachably connected together. The solenoid armature (87) is provided in the first portion (31) and the solenoid coil (85) is provided in the second portion (32). The shroud (109) facilitates separation of the solenoid coil (85) from the solenoid armature (87) without compromising the effectiveness of the electromagnetic means (83). The device (10) providing the combined fuel injection and ignition means is also described and claimed.</p> |
