摘要： A fuel injection valve comprising a main fuel injection valve body containing an electromagnetic coil which is operative to displace a movable core having a valve rod attached to the core. The valve rod has an end with a valve body adapted to selectively engage a valve seat-forming member attached to the valve body. The valve seat-forming member has an interior including a guide bore for guiding opening and closing displacement movements of the valve rod. The guide bore has a uniform diameter throughout its entire length and is connected to a valve seat formed at the end of the guide bore in continuation thereof. A fuel discharge port is formed in continuation of the valve seat. The guide bore is straight and has a burnished surface and the valve seat also has a burnished surface for contact by the valve body. The guide bore is connected to the valve seat without any undercut and due to the burnishing, the guide bore and valve seat are connected without flashing.

摘要： A fuel injection valve comprising a main fuel injection valve body having an inlet opening for fuel and a port for discharge of fuel, a fixed core in the valve body, an electromagnetic coil in the valve body, a movable core attracted magnetically towards the fixed core by the coil and a valve member coupled to the movable core for opening and closing the fuel discharge port. A socket portion is on the valve body to define an end portion for supply of fuel to the inlet opening and the socket portion includes an end flange formed by plastic deformation of the socket portion to dispose the flange radially on the socket portion and provide a radial swarf-free surface on the flange capable of sealed engagement with a connection member having a fuel passage connectible with the fuel inlet. The plastic deformation is achieved by rotating a tool on the edge of the initially straight socket portion to bend an edge portion of the socket portion to form the end flange.

摘要： In a solenoid type fuel injection valve, outer and inner fuel spray guide devices are coaxially disposed downstream of a fuel injection hole, and a pintle is provided at a tip end of a needle valve and projects to extend through the fuel injection hole and opposed to an upper surface of the inner fuel spray guide device. Thus, fuel passing through the fuel injection hole to collide against a valve head of the pintle is sprayed into an intake port, while being atomized and spread into a cone-like shape. At this time, the fuel is blocked by a support arm which extends radially inwardly from a cap to support the inner fuel spray guide device, thereby causing a fuel spray pattern to be formed into a horse's hoof-like shape having fuel non-spray portions. By forming the fuel non-spray portions in correspondence to a rod portion of an intake valve and/or the like, the deposition of the fuel is prevented.

摘要： A solenoid type fuel injection valve for injecting fuel into a plurality of intake ports including a pintle provided at a lower end of a needle valve to protrude into a fuel atomizing space formed at a lower portion of a fuel injection hole, so that the fuel is atomized by collision against the pintle after passing through the fuel injection hole, and the atomized fuel is introduced into a fuel distributing space having an inclined wall surface. A pair of fuel spray guides are supported at a lower end of a cap through support arms, and a fuel injection passage having a horseshoe-like cross-sectional shape is formed around an outer periphery of each of the fuel spray guides. A fuel spray colliding against the inclined wall surface is divided into two flows which are conducted into the pair of fuel injection passages and injected equally into a bifurcated intake port.
