Siphon valve

A siphon valve assembly, the assembly comprising

• a tubular core having an inner surface and an outer surface;
• a head coupled to and surrounding a top of the tubular core;
• a fluid spray initiator coupled to the head;
• a fluid supply valve;
• a first pressurized fluid supply line;
• a second pressurized fluid supply line;
• and
• an actuator,
• 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,
• the tubular core is configured to couple to a toilet tank opening,
• the spray initiator is configured to discharge a pressurized fluid into the tubular core to induce a siphon flow of a surrounding fluid in a toilet tank through the siphon valve inlet, over the weir, out the siphon valve outlet, and into a toilet bowl,
• the head comprises one or more gates extending over a gate opening, the one or more gates configured to be selectively opened and closed to adjust a discharge volume of the toilet tank surrounding fluid,
• the first pressurized fluid supply line is coupled to the fluid supply valve,
• the second pressurized fluid supply line is coupled to the fluid supply valve and the fluid spray initiator, and
• the fluid supply valve is configured to be opened by the actuator to cause the pressurized fluid to flow through the first pressurized fluid supply line, through the fluid supply valve, and through the second pressurized fluid supply line to the fluid spray initiator.
