<p>The device has a valve enclosure (2) region with an axial slide bore (21), an inlet port for feeding fluid into the slide bore and an outlet port (22) for ejecting fluid from the bore, a slide valve (1) movable reciprocally in the bore to control the fluid throughflow rate, a solenoid coil section (4) that generates a magnetomotive force to move the slide valve, whereby a filter device (6) in the slide valve or upstream of the inlet port prevents foreign matter from passing deeper into the valve enclosure.</p> |
