ABSTRACT:
A shut-off valve of the flow rate of a fuel pump for an internal combustion engine; the shut-off valve is provided with: a tubular cylindrical body, which is closed on top, displays a cylindrical seat, the lower portion of which performs the function of fuel pipe, and comprises a number of radial through holes to allow the introduction of fuel within the cylindrical seat; a lower plate, which is arranged within the tubular cylindrical body and underneath the radial holes and has a central through hole which defines an outlet opening of the fuel; and a cylindrical shutter, which is coupled to the lower plate and is mobile between an open position, in which the outlet opening is in communication with the radial holes, and a closed position, in which the outlet opening is isolated from the radial holes.
