- the axial bore in which the shaft is guided has a surface roughness less than Ra 3.2.
- the invention also relates to a common rail diesel fuel injection system comprising a valve made according to any one of the preceding claims.
- Figure 1 is an axial sectional view of a high pressure valve according to the invention.
- Figure 2 is a valve made in a second mode.
- Figure 3 is an alternative mechanical valve that can be adapted to the modes of Figures 1 or 2.
- Figure 4 is an enlarged view of the nozzle of the valve of the preceding figures.
- Figures 1, 2 and 3 show a high pressure valve 10 to be mounted on the common rail 8 of the diesel injection system 6 of an internal combustion engine.
- the valve 10 comprises a body 12 extending along a longitudinal axis A, an electromagnet 14 whose coil is integral with the body 12 and the core, movable in the body 12 , pilot a shaft 16 axially guided in a central bore 18 of the body 12 between a supported position PA and a withdrawn position PR.
- a nozzle 24 switched by the shaft 16 in an open state EO, when the shaft 16 is in the withdrawn position PR, and a closed state EF when the shaft 16 is in the PA supported position.
- the valve 10 is fixed to the ramp 8 by arranging a cylindrical surface of the body 12 in a space of the ramp 8 provided with a complementary female bore. A seal is placed at the interface between the body 12 and the ramp 8.
- the nozzle 24, particularly detailed in Figure 4, essentially comprises a fixed member 22 cooperating with a movable shutter member 24.
- the fixed member 22 extends axially along a cylindrical tubular portion 26 and then along a radial shoulder 28 leading to a cylindrical base 30 of larger diameter, the base 30 extending to a radial surface 32.
- the base 30 complements complementarily in a counterbore 34.
- the counterbore 34 is formed in the body 12 and the fixed member 22 is integral with the body 12, the radial shoulder 28 abutting against the bottom of the countersink 34.

- the fuel pressure in the ramp 8 exceeds the preset limit L, the fuel pushes the shutter member 24 by pressing on its conical portion 54 and opens the discharge orifice 46.
- the pressurized fuel can then be evacuated by passing successively from the ramp 8 to the discharge orifice 46 and then into the guide cylinder 42, through the connection orifice 48, in the interspace 38 to arrive in the evacuation channel 40.
- the electromagnet is replaced by a compression spring 56 actuator permanently urging the shaft 16 towards the supported position PA.
- the spring 56 exerts on the shaft 16 a force calibrated to the preselected limit pressure L of the fuel in the ramp 8. When the pressure in the ramp 8 exceeds said limit L, it overcomes the force of the spring 56 which compresses slightly leaving the When the pressure has fallen below the limit pressure L, the force exerted by the spring 56 prevails and the discharge orifice 46 is again closed.
- the role of the shaft 16 is limited to that of the pusher of the shutter member 24 and the role of the shutter member 24 is for it to close the discharge port 46. From the point of view of manufacture the Machining tolerances are adapted to the role of each piece.
- the shaft 16 and the axial bore 18 of the body 12 can be made taking into account firstly a dimensional tolerance of 30 ⁇ between their diameters, whereas it was 12 ⁇ previously and secondly , of a state quality of their surfaces of Ra 3.2 whereas it was Ra 1.6 previously.
- the steel of the shutter member 24 remains of high quality, the steel used for the shaft 16 may be more ordinary.
