Abstract:
Valve body (6) for a fuel injector (1); the valve body (6) comprising a cylindrical tubular container which has a central cylindrical cavity (17), a valve seat (16) which is disposed at a lower end of the tubular container (14), a pin (15) which can engage the valve seat (16) and is accommodated in a sliding manner inside the tubular container (14), a pair of lower and upper guides (25, 22) which can support the pin (15) in a sliding manner and are accommodated by the tubular container (14), and a support element (19), which is disposed at an upper end of the tubular container (14), accommodates the said upper guide (22), and defines at least one supply aperture (20) which opens into the cavity (17) for supply of fuel to the cavity (17) itself; said support element (19) defining two said supply apertures (20), which open into the said central cavity (17) and are disposed symmetrically on opposite sides of a central axis (2) of the said tubular container (14); and said support element (19) being defined by a bar, which is disposed symmetrically along a diameter of the circular upper end of the said tubular container (14) and has a width which is smaller than the dimension of the said cavity (17) such as to define laterally the said supply apertures (20).
