摘要： In a gas-supply system for internal-combustion engines, a pressure-reducing valve is set between the reservoir of the gas and a distribution manifold or rail that feeds the gas to a series of electromagnetically controlled injectors associated to the various cylinders of the engine. The pressure-reducing valve brings about a pressure drop which depends upon a pilot-pressure signal that is sent thereto by a pilot solenoid valve. The electrical supply to the solenoid of said pilot solenoid valve is controlled by an electronic control unit according to the signal issued by a sensor of the pressure in the rail for the purpose of regulating the pressure in the rail at a desired level, according to the operating conditions of the engine.

摘要： In a gas-supply system for internal-combustion engines, a pressure-reducing valve is set between the reservoir of the gas and a distribution manifold or rail that feeds the gas to a series of electromagnetically controlled injectors associated to the various cylinders of the engine. The pressure-reducing valve has a piston member that faces a chamber set downstream of a restricted passage defined inside the body of the valve in communication between the inlet connector and the outlet connector. The piston member is pushed by thrust means towards a position in which it causes opening of an open/close element that controls the communication between said restricted passage and the inlet connector. The piston member is preferably provided with a single seal gasket that prevents leakage of gas towards the outside through the sliding coupling of the piston member within the respective guide bushing. The thrust means to which the piston member is subject may be constituted by spring means, or else by a pilot-pressure signal, in the case where it is intended to obtain a variable reduction of the pressure according to the operating conditions of the system.

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： In order to reduce the size of a tubular rail for a high-pressure fluid, the rail is obtained from a hollow body with an external diameter and an internal diameter, and has two terminal portions, each provided with an external milling to favour gripping thereof. The millings have an external diameter such as to ensure, together with a cylindrical portion of a coaxial element, a radial strength at least equal to that of the hollow body. Made between the hollow body and each cylindrical portion is a front connection. For this purpose, the cylindrical portion has a plane front surface, whilst each terminal portion has an internal milling with an internal diameter greater than the internal diameter of the hollow body so as to house the cylindrical portion and so as to form an annular shoulder. A washer of softer material is set between the annular shoulder and the front surface.

摘要： In a gas-supply system for internal-combustion engines, a pressure-reducing valve is set between the reservoir of the gas and a distribution manifold or rail that feeds the gas to a series of electromagnetically controlled injectors associated to the various cylinders of the engine. The reduced pressure supplied by the pressure-reducing valve is further reduced via a pressure-regulating solenoid valve, to an extent that depends upon the supply current of its solenoid. The electrical supply to the solenoid of said solenoid valve is controlled by an electronic control unit according to the signal issued by a sensor of the pressure in the rail and according to stored maps, which supply the optimal pressure value for each operating condition of the engine.
