Abstract
A flow diverter for diverting flow between a toilet bowl and a toilet tank, the flow diverter having: a body with an inlet, outlet and pressure relief vent; and a flow adjustment mechanism rotatable around the outlet to selectively divert different percentages of flow between the outlet and the pressure relief vent by moving a stopper in and out of the outlet by rotating a sleeve of the flow adjustment mechanism around the outlet.
Claims25
A flow diverter, comprising:
- a body having an inlet, an outlet and a pressure relief vent between the inlet and the outlet;
- a flow adjustment mechanism configured and arranged to selectively divert different percentages of flow between the outlet and the pressure relief vent, the flow mechanism comprising a rotatable element positioned on the body around the outlet;
- and
- wherein a siphon force applied to the outlet is configured to draw air into the pressure relief vent.

A flow diverter comprising:
- a body having an inlet, an outlet and a pressure relief vent between the inlet and the outlet;
- a flow adjustment mechanism configured and arranged to selectively divert different percentages of fluid flow between the outlet and the pressure relief vent, wherein the flow adjustment mechanism is rotatable around the outlet of the body and comprises:
- a rotatable element received over the outlet, the rotatable element having a threaded inner surface that is configured to mate with a threaded outer surface of the outlet;
- and
- a stopper that is slidably received into the outlet.

A flow diverter comprising:
- a body having an inlet, a first outlet and a second outlet;
- and
- a fluid flow adjustment mechanism rotatable within the body and configured and arranged to selectively divert different percentages of fluid flow between the first outlet and the second outlet,
- wherein the body has a cylindrical section, and wherein the flow adjustment mechanism comprises a curved rotatable wall portion that can be rotated in the cylindrical section to change or block fluid flow into either the first outlet or the second outlet,
- wherein the rotatable wall has a C-shaped or W-shaped cross-section that extends at least approximately one half of the way around the cylindrical section.

A flow diverter, comprising:
- a body having an inlet, a first outlet and a second outlet;
- and
- a flow adjustment mechanism rotatable within the body and configured and arranged to selectively divert different percentages of fluid flow between the first outlet and the second outlet;
- and
- an air vent and diaphragm in the body configured and arranged to prevent a siphon fluid flow from the first or second outlet back to the inlet.
