Embodiment Construction

[0035] As will now be described in detail with reference to the accompanying drawings, the present invention relates to a siphon flush valve, system and method for a toilet. The siphon flush valve is preferably unbaffled. The flush valve system may be configured to provide initiation and termination of siphon flow for flushing. Siphon flow can be induced by the spray actuator causing a pressure differential within the valve.

[0036] Flush valves typically include a core, head, and spray actuator. The head and core can be concentric and the spray actuator can be placed on top of the siphon flush valve. In use, the flush valve may be placed in a tank having a starting tank level sufficient to reach the top of the head. To initiate operation of the flush valve, pressurized water initiates a spray into the core creating a pressure differential within the core causing the tank level to rise in the head and overflow the valve weir and into the core. This establishes a siphonic ...

Abstract

A siphon valve assembly, the assembly comprising a tubular core; a head coupled to and surrounding a top of the core; and a fluid spray initiator coupled to the head; wherein a lower end of the head defines a siphon valve inlet, a lower end of the tubular core defines a siphon valve outlet, an upper end of the tubular core comprises a weir, and the spray initiator is configured to discharge a fluid into the core to induce a siphon flow of a surrounding fluid through the siphon valve inlet, over the weir, and out the siphon valve outlet.

Description

[0001] The present invention generally relates to a flush valve for a toilet system, such as a toilet tank for a cistern toilet. In particular, the present invention relates to a siphon flush valve including a spray actuator positioned to activate the siphon, a damperless flush system and a method of activating the siphon function. Background technique [0002] Tank toilets are widely used in residential and commercial use. Tank toilets may include a flush system that has a fill valve and a flush valve with a flapper to regulate the flow of water to the toilet bowl. Flapper-style flush valves have a flapper seal below the water line that can be prone to leaks due to wear and / or exposure to chemicals. A toilet flapper can be the main cause of a leaking or running toilet. Improved flush valve technology is needed. More particularly, there is a need for a reliable flapperless valve for a toilet tank of a cistern toilet to optimize functionality and / or avoid leaks. Contents o...
