Abstract
The solenoid valve has a fuel feed conduit, and a shutter in the form of a ball controlled by an electromagnet and cooperating with a conical seat in the conduit. The conduit has a fuel filter for preventing particles of dirt from getting between the seat and the shutter, without causing an excessive fall in fuel pressure. The filter is defined by a metal plate having a number of holes of about 0.1 mm in diameter and formed using laser technology; and the plate is fitted to the opposite end of the conduit from the seat.
