摘要： Pressure reducer for compressed gases, comprising at least one regulation stage constituted by a chamber divided by a first membrane (25) into two chambers (23, 24), one of which said chambers (24) is maintained at a reference pressure and the other (23) at a pressure which depends on the gas pressure in the outlet pipe (3), an opening, closed by a membrane (43) integral with a cap (42), located between the said chamber (24) at the reference pressure and the said gas outlet pipe (3), a gas inlet chamber (10) with an opening (11) which leads to the said outlet pipe (3) in correspondence with the said cap (42), the movements of which said cap open and close the passage (11) between the said inlet chamber (10) and the said outlet pipe (3), and means (41) integral with the said first membrane (25) which act on the said cap (42) so that it approaches and retracts from opening (11) of the said gas inlet chamber. It is provided an additional regulation stage constituted by a chamber divided by a membrane (14) into two chambers (15, 16), one of which said chambers (16) is maintained at the reference pressure while the second such chamber (15) is maintained at the reduced gas inlet pressure into chamber (10), regulation means (19) being also provided, designed to act on the said membrane (14) to regulate the said reduced inlet pressure in the said gas inlet chamber (10), and a valve (5) designed to close a highpressure gas inlet pipe (2, 4), which said valve (5) is integral with the said membrane (14), and means (12, 13) which place the said chamber (15) in communication with the area close to the outlet opening (11) of the said gas entry chamber (10).

摘要： Die Vorrichtung (A) zum Variieren der für den Betrieb eines Verbrennungsmotors notwendigen Gasmenge wird zwischen den Druckminderer und das Venturirohr des Mischers zum Mischen von Luft und Gas eingebaut.
Diese Vorrichtung besteht aus einer Leitung (16), in der ein einstellbares Drosselorgan (18), das den Gasdurchgang steuert, betriebsmässig mit der auf den Unterdruck stromab der steuernden Drosselklappe ansprechenden Membran (30) gekoppelt ist. Dieser Unterdruck kann durch ein elektrisch betätigtes Ventil unterbrochen werden, das durch die Stellung dieser mit dem Gaspedal gekoppelten Drosselklappe gesteuert wird. Eine weitere Drosseleinrichtung kann entweder direkt in die Vorrichtung (A) eingebaut oder stromauf oder stromab davon vorgesehen sein. Diese Einrichtung besteht aus einer Leitung, in der ein oder mehrere einstellbare Drosselorgane, die den Gasdurchgang steuern, betriebsmässig mit elektromagnetischen Spulen gekoppelt sind, die getrennt in geeigneter Weise durch einen elektronischen Drehzahlmesser angesteuert werden. Eine weitere Einrichtung, die mit einem Fühler für die Temperatur des Gases am Ausgang des Druckminderers und mit einem elektrisch betätigten Ventil zum Abschalten des vom Motor kommenden und zum Verdampfen des Gases notwendigen Wassers gekoppelt ist, kann zusätzlich zu dem Zwecke vorgesehen sein, die Temperatur des Gases für die Speisung des Motors konstant zu halten. Ebenso kann zusätzlich eine Einrichtung vorgesehen werden, die bei vorgegebenen Werten für den Unterdruck stromab der Drosselklappe die Abschaltung der Minimalgasmenge am Ausgang des Druckminderers auslöst.

摘要： This invention relates to a unit for the supply of liquid petroleum gas (LPG) to internal combustion engines, characterised in that it includes an isobaric vaporiser (5) in series with a pressure reducer (10).
In particular, the unit comprises a vaporiser constituted by a heated tubular element (12) inside which the gas emitted from the tank flows in such a way that it vaporises, the outlet of the said vaporiser being directed towards a filter (7) that removes all impurities from the gas vapour. Downstream, a pressure reducer (10) conveys the gas at the ideal pressure to fuel the engine.
