Abstract

A coupling connects a pressurized flush water vessel held in a toilet tank to a toilet bowl. The coupling has a passageway which provides direct fluid communication between the vessel and the bowl and a chamber for accumulating drainage, which may be exhausted into the toilet tank from inlet devices for the pressure vessel. A swinging door type one way valve substantially seals against leakage from the passageway to the chamber but allows drainage accumulated in the chamber to flow through a port to the passageway. The inlet to the chamber is above the port and at or below the bottom of the toilet tank and the port and the chamber inlet open above the spill level of the toilet. The inlet of the coupling is offset from the outlet and a cradle elevates the pressure vessel above the toilet tank bottom and captures heads of fasteners which secure the toilet tank to the toilet bowl.

Dependent claims

A coupling for providing communication between a pressurized flush water supply for a toilet and a toilet bowl, comprising:

a housing having an inlet portion for connection to an outlet of said pressurized flush water supply, an outlet portion for connection to an inlet of said toilet bowl and a passageway providing communication between said inlet portion and said outlet portion for providing communication between said outlet of said pressurized flush water supply and said inlet of said toilet bowl;
a chamber in said housing adjacent to said passageway;
and
an opening in said housing defining an inlet to said chamber for collecting drainage from outside of said chamber and admitting said drainage into said chamber;
and
a valve in said housing having a port between said chamber and said passageway and means for opening and closing said port for controlling fluid communication between said chamber and said passageway such that liquid drainage accumulated in said chamber can pass through said valve to said passageway and substantial fluid communication from said passageway to said chamber is prevented.
