Adjustable metering valve for an internal combustion engine fuel injector |
摘要 |
The metering valve is controlled by the armature of an electromagnet; the travel of the armature towards the electromagnet is arrested by a stop member integral with a flange fitted to a hollow body by a ring nut connecting the skirt of the electromagnet; a spacer washer made of elastically compressible material is provided between the flange and a shoulder of the hollow body; and the tightening torque of the ring nut compresses the washer accordingly to adjust the travel of the armature. According to a variation, a washer of rigid material is provided between the flange and the shoulder, and is small in width to form a projecting annular portion of the flange, which portion of the flange is flexed accordingly by the tightening torque of the ring nut.
