A compact, automatic mechanical fluid shut-off device which can detect a sustained leak in a pipe as well as a pipe burst and automatically shuts off fluid flow in the pipe. The device is detachable, easy to install, and easy to retrofit into existing pipes. The device employs a unique combination of bias mechanism and fluid flow channels to achieve an automated method of stopping a fluid flow when there is an abnormal fluid flow in the pipe due to pipe burst or sustained leak.
[ What is claimed is:] [1.] An automatic shut-off safety device which stops a fluid flow through at least a portion of a fluid delivery system when abnormal fluid flow occurs, said safety device comprising:a conduit including an influent port and an effluent port adapted to be installed within the fluid delivery system;a valve positioned between said influent and effluent port of said conduit and arranged to selectively block fluid flow through said conduit;a housing comprising a control chamber in which a movable partition is enclosed, said movable part...
