<p>The solenoid valve (5) has a fuel feed conduit (7), and a shutter in the form of a ball (12) controlled by an electromagnet (14) and cooperating with a conical seat (13) in the conduit (7). The conduit has a fuel filter (18, 19) for preventing particles of dirt from getting between the seat (13) and the shutter (12), without causing an excessive fall in fuel pressure. The filter (18, 19) is defined by a metal plate (18) having a number of holes (19) of about 0.1 mm in diameter and formed using laser technology; and the plate (18) is fitted to the opposite end (21) of the conduit (7) from the seat (13). <IMAGE> <IMAGE></p> |
