Summary:An attitude sensing device for triggering a closing mechanism on a fuel dispensing nozzle 18 includes a rolling element 86 disposed within a non-cylindrical chamber 84 sealed with a stopper 88 such that the rolling element 86 may freely move within the chamber 84. A vacuum sensing path 76 passes from a sensing port 74 in the nozzle spout 72, through the vacuum sensing tube 70, into the non-cylindrical chamber 84, and into the venturi generated vacuum chamber 68. The attitude sensing arrangement is configured such that when the nozzle 18 is raised to a certain closing angle, the rolling element 86 blocks a closing port 92 in the non-cylindrical chamber 84. The closing mechanism closes the main fuel valve 48 when the vacuum sensing path 76 is blocked in this manner by the rolling element 86. 一种用于触发燃料分配喷嘴18上的关闭机构的姿态感测装置，其包括设置在非圆柱形室84内的滚动元件86，该室用塞子88密封，使得滚动元件86可以在室84内自由移动。真空感测路径76从喷嘴喷口72中的感测端口74穿过，通过真空感测管70，进入非圆柱形室84并进入文丘里管生成的真空室68。姿态感测装置配置成使得，当喷嘴18升高到一定的关闭角度时，滚动元件86阻挡非圆柱形室84中的关闭端口92。当真空感测路径76以这种方式被滚动元件86阻挡时，关闭机构
