<p>A stepped internal pole (2), concentric with the axis (1) of the valve, is partly surrounded by the electromagnet winding (4). A blind hole (7) in its end (6) accepts a pin (38) protruding into a bore (30) through the armature (34). - The cover (10) and sleeve (9) are relatively movable to vary the cross-section of the magnetic cover until the quantity delivered from the valve to a measuring cylinder (73) between opening and closing corresponds to a preset desired value.</p> |
