摘要： The present invention relates to a blocking device (10) for pipelines for the passage of pressurised gas, of the pilot-operated type, comprising: - a blocking valve (11); - a fluid-dynamic actuator (18) configured to translate the stem (17) of the movable shutter (16) of the blocking valve along the main axis (X) of the same stem (17); - thrust means (19) configured to bring the movable shutter (16) from an operating position of opening to an operating position of complete closure; - a control system (20) for the controlled actuation of the fluid-dynamic actuator (18), comprising a by-pass group (21) for equalising the upstream (P1) and downstream (P2) pressures and a pressure reducer group (22) interconnected with the by-pass group (21). The control system (20) comprises a pressure differential selector device (23) configured to detect a signal of the upstream pressure (P1) and a signal of the downstream pressure (P2) and to determine alternately: - the passage of a supply fluid through the pressure reducer (22) towards the fluid-dynamic actuator (18) if the difference between the upstream (P1) and downstream (P2) pressures is less than a predetermined balancing pressure difference (Peq); - the interception of the supply fluid and the failure to supply the fluid-dynamic actuator (18) if the difference between the upstream (P1) and downstream (P2) pressures is greater than or equal to the balancing pressure difference (Peq).

摘要： A mobile dispenser may be used to at least partially fill hydrogen tanks of fuel cell-powered vehicles and uses a purely mechanical control of the fill using an orifice plate across which a pressure differential is maintained through use of a backpressure regulator whose reference pressure is controlled by a differential pressure regulator. Because it does need or use electrical power, it may be used in situations where no electrical power is available or convenient.

摘要： A valve assembly capable of converting a small leak of a device into a measurable, relatively larger or "burst" flow event is described. In certain embodiments, the valve assembly includes a compliant chamber and, following pressurization of the device, permits flow when the pressure in the compliant chamber drops to a configured fill pressure and restricts (or prevents) flow when the pressure in the compliant chamber increases to a shut-off pressure. The disclosed valve assemblies may be incorporated into a leak detection assembly capable of transmitting usage and/or alarm data to a central service.
