A fill valve assembly (9, 109) for connection with a flushing syphon or other flushing valve. The assembly (9, 109) includes a float operated equilibrium valve (90, 190) and a branch element (92, 192) fluidly connected upstream the equilibrium valve (90, 190) and including an outlet (98) for providing fluid flow to one or more fluid pressure driven actuators (6).

A flush toilet apparatus for discharging waste by a jet pump action is disclosed. The flush toilet apparatus has an overflow portion configured to overflow a portion of flush water flowing from a throat pipe into a water conduit into a reservoir tank so that when the flow rate of water flowing inside the throat pipe exceeds a predetermined specified flow rate, the flow rate of water supplied from the water conduit to a bowl portion is reduced to less than a predetermined specified flow rate.

A touchless siphon valve assembly for a toilet assembly having a toilet tank, the touchless siphon valve assembly comprising a control assembly and a siphon valve assembly, wherein the control assembly comprises a capacitive sensor, a controller, and a power source, and the siphon valve assembly comprises a tubular core, a head coupled to and surrounding an upper end of the tubular core, a spray initiator positioned in the head and extending into the tubular core, and a solenoid valve fluidly coupled to the spray initiator, the capacitive sensor is configured to detect a user gesture, and to indicate detection of the first gesture to the controller to initiate a flush cycle.
