Claims
- 1. An electromagnetically operated fuel injection valve comprising a valve housing; a valve seat body having a valve seat and a guide cylinder provided with spiral flutes; a valve closing element projecting in and guided by said guide cylinder with said spiral flutes and supporting a ball type valve closing body around which fuel can flow through said spiral flutes in which said valve closing element interrupts or releases a fuel flow by sitting on or lifting off said valve seat, said valve seat body, in addition to said guide cylinder and said valve seat, also containing at least one outlet orifice, and said valve seat body being provided with a groove-like surrounding flute between said guide cylinder and said valve seat, said valve seat body being formed as a one-piece element which contains said guide cylinder, said valve seat, said outlet orifice and said groove-like surrounding flute.
- 2. An electromagnetically operated fuel injection valve as defined in claim 1, wherein said guide cylinder has a wall provided with said spiral flutes through which the fuel can flow.
- 3. An electromagnetically operated fuel injection valve as defined in claim 1, wherein said guide cylinder is a stamped member.
- 4. An electromagnetically operated fuel injection valve as defined in claim 1, wherein said valve seat is a stamped member.
- 5. An electromagnetically operated fuel injection valve as defined in claim 1, wherein said spiral flutes in said valve seat body are stamped formations.
- 6. An electromagnetically operated fuel injection valve as defined in claim 1, wherein said guide cylinder, said valve seat and said spiral flutes and said valve seat body are stamped members.
- 7. An electromagnetically operated fuel injection valve as defined in claim 1; and further comprising a welded connection that supports said valve seat body in said valve housing.
- 8. An electromagnetically operated fuel injection valve comprising a valve housing; a valve seat body having a valve seat and a guide cylinder provided with spiral flutes; a valve closing element projecting in and guided by said guide cylinder with said spiral flutes and supporting a ball type valve closing body around which fuel can flow through said spiral flutes in which said valve closing element interrupts or releases a fuel flow by sitting on or lifting off said valve seat, said valve seat body, in addition to said guide cylinder and said valve seat, also containing at least one outlet orifice, and said valve seat body being provided with a groove-like surrounding flute between said guide cylinder and said valve seat, said valve seat body being formed as a one-piece element which contains said guide cylinder, said valve seat, said outlet orifice and said groove-like surrounding flute, said valve seat body forming a free end of the fuel injection valve and being arranged directly near an inlet valve of an internal combustion engine.
