    摘要: A pressure regulator device (10) for fuel gas plants in internal combustion engines, particularly for the automotive field, is described, the device being interposed between a tank for the gas at high pressure and a line (4) for sending the gas to the engine. The device comprises at least a first stage (1) for gas pressure reduction, bearing respective gas inlet (la) and outlet (lb) openings, the inlet opening (la) being in fluid communication with the gas tank, the pressure of the gas regulated by the first stage (2) being of an intermediate value between the gas pressure upstream and downstream of the device, at least a second stage (2) for gas pressure regulation, of the type comprising a regulating resilient membrane (15) placed downstream of the first stage (1), the membrane separating between them a first and a second chamber ( 16, 17) of the second stage (2), the regulated gas being supplied with the intermediate pressure into the first chamber (16) and the gas being delivered from the first chamber (16) at the preselected pressure for sending to the engine. The second stage (2) bears respective gas inlet (2a) and outlet (2b) openings, the outlet opening (2b) from the second stage (2) being in fluid communication with the line (4) for sending the gas to the engine. The device further comprises a secondary circuit associated with the device and connected in parallel with the second pressure regulation stage (2), the circuit comprising an auxiliary duct (21) designed to connect, with fluid communication, the second chamber (17) of the second stage (2) with the line (4) for sending gas to the engine, a valve unit comprising a valve seat (22) with a respective shutter member (23) and an electromagnetic actuator (24) operatively connected to the shutter member (23) in order to control the latter with respect to the valve seat (22), the actuator (24) being controlled by an electronic control unit (30) which, according to the pressure value at the outlet from the device (10) controls the opening of the shutter member (23) in order to regulate the gas pressure in the first chamber (16) of the second stage (2), so as to keep the pressure value at the outlet of the device stable.

    摘要: Die Erfindung betrifft einen Gasdruckregler, bei dem in einem Gehäuse (1) eine erste Regelstufe (R1) und eine der ersten Regelstufe (R1) stromabwärts nachgeschaltete zweite Regelstufe (R2) aufgenommen sind, wobei die erste (R1) und die zweite Regelstufe (R2) über einen verschließbaren Durchbruch (9) miteinander verbunden sind. Zur Verbesserung der Sicherheit des Gasdruckreglers wird erfindungsgemäß vorgeschlagen, dass die zweite Regelstufe (R2) eine Gasmangelsicherungseinrichtung (13, 14, 15, 16, 17, 18) mit einem manuell betätigbaren Stellmittel (16, 18) aufweist, mittels derer bei einem Druckabfall in der zweiten Regelstufe (R2) unter einen vorgegebenen Mindestwert der Durchbruch (9) automatisch derart verschließbar ist, dass ein Regelbetrieb erst nach manueller Betätigung des Stellmittels (16, 18) möglich ist.

    摘要: The invention relates to a valve device (14) for low-viscosity to high-viscosity fluids, especially for fluid plastic material constituents (12) of single or multiple constituent plastic mixtures. The inventive valve device comprises a valve housing (18) with a fluid inflow (20, 30) and a dosing valve (15) which has a dosing nozzle (22) that can be optionally closed or opened by a closing element (23). Said valve device also comprises a pressure control device (40, 44) which influences the fluid in the fluid inflow. In order to maintain a constant fluid pressure in the housing which is not influenced by the position of the closing element, the invention provides that the pressure control device is essentially comprised of a control membrane (40) which can be pneumatically prestressed and which acts upon the closing element (23). The invention enables a particularly easy isobaric control or regulation of the fluid inflow since the fluid pressure on one side of the membrane and acting upon the same is in equilibrium with the air pressure prevailing on the other side, and since the air pressure and thus the control membrane remain practically unchanged due to the compressibility of the gas when the closing element is displaced.

    摘要: A two-stage pressure regulator with dual safety system, particularly for liquefied-gas cylinders comprising a body (1) which is provided with means (2,3,4) for removable coupling to a liquefied-gas cylinder and forms a first control stage (11) and a second control stage (18) for limiting and regulating the pressure of the gas in output. There is also a pin (15) for actuating the outlet valve of the cylinder, which is controlled by an actuation element which is actuatable by actuation means which can be accessed from outside the body, and further comprising means (40) for the removable locking of the coupling means (2,3,4) which are adapted to prevent the uncoupling and coupling of the body (1) with respect to the cylinder while the actuation pin (15) is in the position for opening the outlet valve.
