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： 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.
