Abstract

A solenoid valve includes a body 2, an intake pipe 14, an outlet passage 8, a coil 4 and a movable stem 3, urged by a spring 10 toward a valve open or closed position. The stem 3 defines, with a seat 20, an annular sealing surface 22, surrounded by a groove 17 and by an annular flange 18. The flange defines, with an annular counterpart placed opposite, an annular damping zone 23. The groove 17 communicates with the outlet passage 8 through a longitudinal slot 12 provided in the stem 3. The annular flange 18 is in a position near or in contact with its counterpart in the zone 23 when the valve is closed. During a closing of the valve, the liquid in the annular zone 23 escapes radially through the groove 17 from between the annular damping surfaces. This produces a braking effect on the stem 3, to reduce wear on the annular sealing surface 22. <IMAGE>
