摘要： The metering servo valve comprises a valve body, an open/close element, and an electromagnet, and is housed in a shell of the injector. The electromagnet actuates a mobile armature for a travel defined by an arrest element, carried by the electromagnet, which is housed in a casing, fixed in the shell by means of a threaded ring nut. Said ring nut is screwed with a pre-set tightening torque on a thread of the shell. The casing has a resting surface designed to engage a shoulder of the shell. The surface is carried by an area of the casing designed to undergo deformation as a function of the tightening torque of the ring nut so as to enable fine adjustment of the travel of the armature.

摘要： A method is provided for controlling fuel injection in an internal-combustion engine provided with an electroinjector, including an electroactuator, an injection nozzle, and a pin, which is movable along an opening stroke and a closing stroke for opening/closing the nozzle under the control of the electroactuator and according to the supply pressure of the fuel into the electroinjector. The method supplies to the electroactuator a first electrical command and at least a second electrical command, which are sufficiently close to one another as to displace the pin with a profile of motion without any discontinuity in time, and such as to cause the pin to perform a first opening displacement and, respectively, a second opening displacement. Between one injection and the next, at least one among the following quantities is varied as a function of operating parameters of the engine: duration of at least one among the electrical commands; number of the electrical commands; and distance in time between the electrical commands.

摘要： A system for controlling filling a motor-vehicle tank with LPG, comprises: a normally-closed valve, which can be driven in opening by excitation of a solenoid; sensor means, pre-arranged to emit an electrical signal indicating that a pre-set maximum level of LPG in the tank has been reached; and a control member, which can be operated manually for generating an electrical signal indicating the intention to proceed with filling the tank. The system further comprises a control circuit, which is independent of the circuit on board the motor vehicle and which is active even when the vehicle engine is turned off and is pre-arranged for exciting the solenoid of the valve in order to control opening thereof when it receives the aforesaid signal indicating activation of the mode of filling of the tank, and for de-exciting the aforesaid solenoid in order to control closing of the valve when the signal indicating that the pre-set maximum level of LPG in the tank has been reached is received. Preferably, the aforesaid valve is of the servo type, in which the solenoid controls an auxiliary open/close element associated to a pilot hole, opening of which causes opening of a main open/close element.
