    • A fire extinguishing system including a vessel having an outlet normally sealed by a frangible seal. A probe is aligned with the seal and is mounted for movement in a path intersecting the seal and spring biases the probe toward the seal in the path. A restraint is provided for normally restraining the probe in the path to prevent breakage of the seal and includes a radially outwardly opening annular groove in the probe, a series of spherical elements disposed such that they partially enter the groove, and a movable cam which abuts the spherical elements oppositely of the groove and which is configured to cam the elements partially into the groove. A releasable latch holds the cam in abutment with the spherical elements and the elements, the cam and the groove are constructed and arranged such that upon release of the latch, the spring will drive the probe to move the spherical elements against the unlatched cam and move the same to a position whereat the spherical elements are out of the groove to fully release the probe for movement toward the seal.
    • 一种灭火系统,包括具有通常由易碎密封件密封的出口的容器。 探针与密封件对准,并且安装成在与密封件相交的路径中移动,并且弹簧将探针偏压到路径中的密封件。 提供了一种限制器,用于在路径中正常地限制探头以防止密封件损坏,并且包括在探针中的径向向外开口的环形槽,一系列球形元件设置成使得它们部分地进入凹槽,以及可移动凸轮,其邻接 所述球形元件与所述凹槽相对并被构造成将所述元件部分地凸入所述凹槽中。 可释放的闩锁将凸轮保持为与球形元件邻接并且元件,凸轮和凹槽被构造和布置成使得在释放闩锁时,弹簧将驱动探头以将球形元件移动抵靠未锁定的凸轮并且移动 与球形元件离开凹槽的位置相同,以完全释放探针以朝向密封件移动。
