Abstract
A direct injection fuel injection valve includes a valve assembly 6, a hollow housing 14 having a coupling portion 16 coupled to the valve assembly and adapted to be connected to the fuel supply pipe 5, and a solenoid assembly 22 disposed for operating the valve assembly. The housing has an abutting surface 36 disposed at a position radially outward of the coupling portion with respect to the valve assembly and in an opposing relationship relative to a shoulder portion 3 of the fuel injection valve insertion hole 2, and a mounting surface 31 for positioning the housing relative to the cylinder head. A sleeve 40 is provided with one end disposed on the valve assembly in opposition to the shoulder portion of the cylinder head and the other end mounted to the housing in abutment against the abutting surface to bridge across the valve assembly and the housing over the coupling portion. A seal ring 45 having one side disposed on the valve assembly in abutment against the one end of the sleeve and the other side adapted to abut against the shoulder portion of the fuel injection valve insertion hole is provided.
