Shaw Aero 快速燃油系統是一种非加压的燃油系统,它利用一个浮子和一个连接信号管的反馈系统在油箱加满时切断燃油流。 该系统包括五个主要功能部件。

  • 通风式盖 (1)

  • 油箱排气口 (2)

  • 浮子 (3)

  • 信号管 (4)

  • 进口阀 (5)

当浮子 (3) 处在下位置时,燃油从喷嘴的接收器进入油箱,并流过打开的进口阀 (5) 。 少量的燃油通过一个柔性不锈钢编织信号管 (4) 进入浮子 (3) 。 在加注过程中,排出的燃油从浮子 (3) 自由溢出到油箱内,而空气通过安全阀 (2) 排出到油箱外。 在燃油开始流入后,排气口 (2) 不会立即打开,而是只有在油箱内聚集起了一定的空气压力后,才会打开。 较大的油箱可能需要较多的加注量,然后排气口才会打开。

随着油箱中燃油增多,燃油油位开始使浮子 (3) 升高。 当浮子 (3) 升高时,浮子堵住信号管 (4) 以及排出的燃油流。 随着信号管 (4) 中的压力逐渐累积,进口阀 (5) 关闭,从而切断进入油箱的燃油流。 燃油喷嘴因为背压而分离。 当浮子 (3) 处于上位置时,进口阀 (5) 被液压锁闭,而燃油无法泵入油箱。
