Abstract
A flow diverter for diverting flow between a toilet bowl and a toilet tank, having: a body having an inlet, a first outlet and a second outlet; and a flow adjustment mechanism rotatable within the body to selectively divert different percentages of flow between the first outlet and the second outlet; and an air vent and diaphragm in the body to prevent a siphon flow from the first or second outlet back to the inlet.
Claims22
A flow diverter for diverting flow between a toilet bowl and a toilet tank, comprising:
- a body having an inlet, an outlet and a pressure relief vent between the inlet and the outlet;
- and
- a flow adjustment mechanism to selectively divert different percentages of flow between the outlet and the pressure relief vent,
- wherein a siphon force applied to the outlet draws air into the pressure relief vent.
A flow diverter for diverting flow between a toilet bowl and a toilet tank, comprising:
- a body having an inlet, an outlet and a pressure relief vent between the inlet and the outlet;
- and
- a flow adjustment mechanism to selectively divert different percentages of 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 sleeve received over the outlet, the sleeve having a threaded inner surface that mates with a threaded outer surface of the outlet;
- and
- a stopper that is slidably received into the outlet.
A flow diverter for diverting flow between a toilet bowl and a toilet tank, comprising:
- a body having an inlet, a first outlet and a second outlet;
- and
- a flow adjustment mechanism rotatable within the body to selectively divert different percentages of 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 block 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 quarter of the way around the cylindrical section.
