摘要： A metering valve presenting a shutter for a discharge conduit, and an eleomagnet in turn presenting a fixed core and a disk-shaped armature detached from and sliding on the stem by means of a sleeve. The stem is guided by a bush, presents a flange movable inside a swirl chamber with a velocity damping effect, and is fitted, prior to assembling the armature and the electromagnet, by means of a ring nut, which presses a flange, forming one piece with the bush, against the body of the valve via the interposition of calibrated washers so selected as to define the travel of the stem.

摘要： A metering valve has a valve body with a control chamber, a pressurized f supply conduit and a fuel drain conduit. A control rod of a shutter includes an element for hydraulically affecting the fuel supply conduit and the fuel drain conduit so that fuel drainage is considerably reduced. The control rod slides in a first cylindrical portion of the control chamber. A second portion of the control chamber that is coaxial with the first portion forms an annular shoulder against which the element is arrested. The fuel supply conduit is located radially of the first portion, and the fuel drain conduit is located axially of the second portion of the control chamber.

摘要： A control circuit for supplying a load with current having a high-amplitudeortion with a rapid leading edge, and a lower-amplitude portion. The circuit is input-connected to a low-voltage supply source, and comprises a number of actuator circuits parallel-connected between the input terminals and each including a capacitor and a load. Each actuator circuit also comprises a first controlled switch between the respective load and a reference line, for enabling energy supply and storage by the respective load. A second controlled switch is provided between the capacitor line and the load line, for rapidly discharging the capacitors into the load selected by the first switch and recirculating the load current, or for charging the capacitors with the recirculated load current.

摘要： The valve comprises a shutter for the drain conduit of the control chamberf the injector; and an electromagnet having a fixed core with a seat for a coil which is energized to operate the armature controlling the shutter. The core presents two coaxial annular pole pieces, the outer one of which is shorter than the inner one and fitted with a ring of magnetic material partially closing the seat and enabling a substantial reduction in the diameter of the armature. The smaller diameter of the armature enables it to be fitted to the body of the injector by means of a larger-diameter threaded ring nut. The armature, together with a return spring, is fitted to a plate having a sleeve for guiding the stem; and the assembly is then fitted to the body independently of the electromagnet by screwing the ring nut inside a seat in the body.

摘要： The metering valve is fitted in a hollow body of the injector and is contled by the armature of an electromagnet. The travel of the armature towards the electromagnet is arrested by a stop element fittable to the hollow body by a threaded element, which is screwed to a thread of the hollow body with a calibrated tightening torque to adjust the travel of the armature towards the electromagnet according to of the tightening torque. The method of adjustment includes the steps of fitting the stop element in the hollow body by a threaded element, and applying a calibrated tightening torque to the threaded element.
