    • A system to maintain the pressure within a pressurized container within dgn limits and to vent undesirable fluids to the ambient atmosphere. A float floats near the top of the container on the surface of oil supplied to the container by a pressure compensator and is seated to seal an opening as long as the oil level remains above a given level. Sufficient displacement of the oil by gases generated within the container will unseat the float to allow the venting of such gases to the ambient atmosphere. Another opening is also located in the top of the container and is sealed by a weighted lid. If the pressure in the container exceeds the local ambient atmospheric pressure by an amount that would otherwise rupture the container, the lid will be forced open to allow the relief of the excess pressure. When seated, another float seals an opening located in the bottom of the container. This float will float on atmospheric fluid which accumulates in the bottom of the container. If a given level of accumulated atmospheric fluid is exceeded, the float will become unseated to allow the venting of such fluid. Should the internal pressure of the container drop sufficiently below the local ambient atmospheric pressure, the two floats will unseat to permit the entry of atmospheric fluid to equalize the pressures and prevent the container from being crushed.
    • 将加压容器内的压力维持在设计限制内并将不需要的流体排放到周围环境的系统。 浮子通过压力补偿器在靠近容器表面的油面附近漂浮,并且只要油位保持在给定水平以上就可以将其密封以密封开口。 通过在容器内产生的气体产生的油的足够的排量将使浮子移动,以允许将这些气体排放到周围环境中。 另一个开口也位于容器的顶部,并用加重的盖子密封。 如果容器中的压力超过当地环境大气压力,否则会使容器破裂的量,则盖将被强制打开以允许释放过大的压力。 当安装时,另一个浮子密封位于容器底部的开口。 该浮子将浮在积聚在容器底部的大气中。 如果超过给定水平的积聚大气液体,浮子将变得不合适,以允许这种流体的排放。 如果容器的内部压力足够低于当地的环境大气压力,则两个浮子将不适于允许大气流体进入以均衡压力并防止容器被压碎。
