摘要： A fuel injection valve is provided that can reduce variations in stroke length by reducing distortion during welding, and consequently can reduce variations in flow rate of injected fuel. The fuel injection valve has a nozzle; a fixed valve that is press-fit into a tip of the nozzle and has a fuel injection port from which the fuel is injected; and a movable element that forms a fuel seal section by abutting against the fixed valve, and opens and closes the fuel injection port. The fixed valve and the nozzle are fixed in place by welding at a position with no space due to press-fitting. A groove that serves as an empty space is provided in a continuation of a welded section that is formed in the fixed valve and the nozzle by the welding.

摘要： It is important not to form the partial bump in the collision structural part, however the fixed core and the movable core are relatively inclined due to an accumulation of tolerances and therefore even if each collision structural part of the fixed core and the movable core in formed in a flat shape, the fixed core and the movable core are contacted with not the whole of the collision structural parts but a part of the collision structural parts at the moment of the collision. In a case in which the collision structural part is formed in a ring shape or an intermittent ring shape, the fixed core and the movable core are contacted with each other at outer peripheral parts. Thus, when the fixed core and the movable core are collided with each other, a high stress is applied to the outer peripheral parts contacted first. Accordingly, the shape of the outer peripheral parts of the collision structural parts is important, however since such a part, which is a tiny protruding shape, requires high processing accuracy, to reduce stress occurred during collision while keeping productivity is difficult. In the present invention, an R-shaped part and a flat part are provided in order from an outer peripheral side of a collision structural part. Further, the R-shaped part and the flat part are connected in a tangent manner.

摘要： An object of the invention is to provide a fuel injection valve that applies a swirl to an upstream side of a seat section to shorten spray penetration.When flows into injection hole entries are indicated by arrows 101a to 106a and injection hole exit directions are indicated by arrows 201 to 206, an angle α defined by the inflow direction 101a and the exit direction 201 of an injection hole 71 can be increased. In a method for applying the twisted angle α, a side groove 15a on an outer peripheral side of a guide member 12a is set to be accompanied with a twist with respect to an axis O1. Furthermore, a flow passage area of the side groove 15a is set smaller than a flow passage area on an upstream side of the guide member 12a and is also set larger than a flow passage area of a seat section 7B that is constructed by a gap between a valve body 7 and an orifice cup 7.
