Abstract
A pressure actuated fill tube for toilet tanks is taught which is capable of reducing the flow of water into the toilet tank to a minimum rate when a shower or other water use appliance is running, substantially reducing the likelihood of a shower scalding incident if someone flushes the toilet while someone else is in the shower, and allowing the toilet tank to fill over time. Also taught is a means to implement the required pressure sensitive valve as an integral part of the pressure actuated fill tube for toilet tanks. Also taught is a pressure actuated fill system for toilet tanks that is configured with the pressure sensitive valve located inside the toilet tank.
Claims25
A pressure actuated fill tube for toilet tanks comprising:
- a. An inlet tube,
- b. A pressure sensitive valve that is responsive to changes in water supply pressure, and
- c. An outlet tube.
- Said inlet tube directing the flow of water from the water supply system into said pressure sensitive valve, said pressure sensitive valve controlling the flow of water between a minimum flow rate and a maximum flow rate, and said outlet tube directing the controlled flow of water into said toilet tank.
A pressure actuated fill system for toilet tanks comprising:
- a. A standard toilet tank fill tube connected between a standard toilet tank shut-off valve and a standard toilet tank, and
- b. An integrated pressure sensitive valve, internal to said standard toilet tank, which is responsive to changes in water supply pressure.
- Said standard toilet tank fill tube directing the flow of water into said standard toilet tank through said integrated pressure sensitive valve, said integrated pressure sensitive valve controlling the flow of water between a minimum and a maximum flow rate.
