A device for monitoring the flow of fluid in a pair of conduits and blocking the flow of fluid in a conduit when leakage of fluid is sensed therein. The device is provided with, a pair of inlet and outlet passageways in which fluid flows to and from the conduits, a pair of solenoid operated shutoff valves for blocking the flow of fluid in the inlet passageways and a pair of check valves for blocking the backflow of fluid through the outlet passageways. Means are supplied for (a) sensing the flow of fluid through the passageways and translating the same into an electrical signal for comparison with a norm, and (b) actuating the closing of a shutoff valve to block the flow of fluid into a conduit which is connected between an inlet and outlet passageway in which the electrical signal, corresponding to the flow of fluid therein, differs from the norm, the means being designed to delay actuation of the shutoff valve until it is determined that the change in signal from the norm is the result of actual leakage of fluid from the conduit.

Fluid flow control device for monitoring the fluid flow in a conduit for

An assembly havng a retractable toilet bowl incorporates conduit means in the bowl trunnion for delivering water to the toilet bowl via pipes on its underside. The trunnion conduit means incorporates a Sloan valve of standard commerical type to provide advantageous wetting and flushing flow control while providing safeguards against flooding and inadequate sewer gas trap level. The wetting control extends the range of wetness and facilitates cleaning operations. Right and left hand installations, using the same parts, are enabled. Other features as in models currently marketed remain readily incorporatable.
