Title:
燃料噴射弁
Document Type and Number:
Japanese Patent JP2004510915
Kind Code:
A
Abstract:
The present invention relates to a fuel injector for fuel injection systems of internal combustion engines, including, among others, an actuator (10, 11, 12) and a movable valve part (5, 7) cooperating with a fixed valve-seat (22) formed at a valve-seat member (16), to open and close the valve. Arranged downstream from the valve seat (22) is a disk-shaped swirl element (25) which is provided with at least one inlet region (27) and also at least one outlet opening (29), and which includes at least one swirl channel (28) upstream from the outlet opening (29). The inlet region (27) in the swirl element (25) receives a central inflow. All swirl channels (28) originate from here, so that the fuel, which flows through the swirl channels (28) exclusively from the inside towards the outside in the radial direction, is imparted with a swirl component. The fuel injector is particularly suitable as a high-pressure injector for direct fuel injection into a combustion chamber of a mixture-compressing internal combustion engine using external ignition.
