摘要： A safety valve for pressurized tanks, particularly for tanks for containing methane or LPG for motor vehicles, comprises an open/close element that is kept by elastic means in a closing position, in which it does not enable communication of the internal cavity of the tank with the external atmosphere. When a pre-set maximum value of the pressure inside the tank is exceeded, sufficient for overcoming the load of said elastic means, the open/close element is displaced from its closing position and enables discharge of the gas contained in the tank into the external atmosphere. The elastic means are arranged in series with a fuse element, which is set between the open/close element and the valve body. In this way, whenever the temperature -exceeds a pre-set maximum value, the fuse element melts, causing unloading of said elastic means, which consequently leaves the open/close element free to open. Preferably, associated to the open/close element are sensor means for detecting the displacement of the open/close element from its closing position, which are designed to signal intervention of the safety valve to the driver.

摘要： The fuel injector comprises a hollow casing, fixed on which is a nozzle having a nebulizer for the fuel under pressure, a needle axially mobile for opening and closing the nebulizer by means of a first end thereof, and a control rod, substantially coaxial with the needle and in direct engagement therewith. The needle is normally pushed into a closing position of the nozzle by the fuel under pressure acting on the rod, aided by a compression spring, which acts on the needle through a sleeve that is in axial engagement with a portion of the rod. The sleeve further comprises a surface designed to engage at the front and directly one end of the needle. The spring engages another surface of the sleeve so as to transmit its action directly onto the needle.

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.
