摘要： A fuel flow control valve (10) is adapted to control the flow of fuel in a spill line (52) to control the amount of fuel usable in a two speed gas turbine (56). The valve includes fluid pressure operated valve means (16) controlled by two variable volume fluid pressure chambers (32, 34) to provide appropriate fuel flow for 'run' and 'idle' conditions, and positioning means (18, 24, 64) to automatically position the fluid pressure operated valve means (16) when the control valve (10) is at rest to provide a flow of fuel appropriate for'start-up' of the gas turbine (56) that is greater than the flow required in the 'idle' condition but less than that required in the 'run' condition. Operating fluid pressures connected to the chambers (32, 34) may comprise either gaseous fluid pressures tapped from a stage of the compressor (58) of the gas turbine or a combination of said gaseous pressure source and a liquid fluid pressure source preferably comprising a fuel pressure supply tapped from the fuel supply line (51) to the gas turbine.

摘要： A breathing demand regulator for use in aircrew life support apparatus has an aneroid capsule 56 coacting with a valve head 50 to restrict outflow from a breathing pressure control chamber 32. The aneroid capsule expands to move the valve head in the event of aircraft cabin altitude rising above a predetermined level due to loss of cabin pressure. An end face 53 of a valve stem 51 supporting the valve head senses inflation pressure of an aircrew G-suit by way of a passageway 59 for movement of the valve head in the presence of G-load. This arrangement provides for increased control pressure and, hence, increased breathing gas pressure in a regulator outlet 13, in meeting the higher of requirements for positive pressure breathing to protect an aircrew member exposed to both G-load and high aircraft ambient altitude (say above 12000 metres).
The regulator is disclosed in combination with an anti-G valve arrangement 90, 100 and a G-suit inflation control valve arrangement 60, 61, and 120, 121 that provides the higher of G-suit inflation pressure requirement for protecting the aircrew member when exposed to high aircraft ambient altitude in the presence of G-load.摘要翻译： 用于机组生命支持装置的呼吸需求调节器具有与瓣膜头50共同作用的液体小室56，以限制从呼吸压力控制室32流出。在飞机机舱高度升高的情况下，小型液体容器膨胀以移动瓣膜头 由于机舱压力的丧失而高于预定水平。 支撑阀头的阀杆51的端面53通过通道59检测机组G-套装的充气压力，以在存在G-负载的情况下移动阀头。 这种布置提供了增加的控制压力，并且因此增加了调节器出口13中的呼吸气体压力，满足正压呼吸的要求中的较高要求，以保护机组构件暴露于G-载荷和高飞机环境高度（例如以上 12000米）。 该调节器与抗G阀装置90,100和G套装充气控制阀装置60,61和120,121相结合公开，G装置充气控制阀装置60,61和120,121在保护机组件成员 在G负载的情况下暴露于高飞机环境高度。
