Abstract: A toilet assembly includes a toilet body and a fluidic oscillator. The toilet body defines a toilet bowl that is configured to receive a volume of fluid therein. The fluidic oscillator is coupled to the toilet body in a rim area of the toilet bowl. The fluidic oscillator is positioned to direct a fluid onto an inner surface of the toilet bowl. The fluidic oscillator is configured to continuously redirect the flow of fluid to different locations along the inner surface of the toilet bowl.

Abstract: A shower head includes a water input pipe, a fluidic oscillator, and at least one water outlet. The water input pipe is configured to supply a flow of water. The fluidic oscillator includes at least one predetermined geometry to control the flow of water ejected from the fluidic oscillator to include a repeating fan of water at a predetermined angle range. The at least one water outlet is configured to provide the flow water including the repeating pattern of water.

Abstract: A toilet includes a bowl, a trapway, and a passage. The trapway is fluidly connected to the bowl at a trapway inlet and extends downstream from the bowl. The trapway includes an up-leg and a down-leg extending downstream from the up-leg. The passage is fluidly connected to the trapway downstream from the trapway inlet. The passage is configured to allow ambient air from outside the toilet to pass therethrough toward the trapway.

Abstract: A tankless toilet includes a bowl, a trapway, and a jet. The bowl includes a rim at an upper portion of the bowl and a sump at a lower portion of the bowl. The trapway extends from the sump to a drain. The jet includes a main channel configured to receive a supply of water from a supply conduit, and a plurality of distribution channels configured to introduce water received from the main channel to at least one of the sump and the trapway. The jet is configured to receive the supply of water from the supply conduit at a first flow rate and induce a flow from the supply of water into the trapway at a second flow rate greater than the first flow rate to prime a siphon within the trapway. The second flow rate is greater than the first flow rate prior to priming the siphon.

Abstract: A tank assembly for a pressure-assist toilet includes a flush assembly having an outer chamber and an inner chamber disposed in the outer chamber. The flush assembly further includes a flush valve disposed in the inner chamber, and a pilot valve disposed in the inner chamber and extending through the flush valve. The tank assembly further includes an actuator engaging the pilot valve and configured to hold the pilot valve at each of a first height, a second height offset a first distance from the first height, and a third height offset a second distance from the first height greater than a first distance.

Abstract: A fill valve for receiving a fluid flow includes a lower pipe and a flow restrictor cartridge. The flow restrictor cartridge is received in the lower pipe. The flow restrictor cartridge receives the fluid flow at a first fluid flow rate and provides the fluid flow as a second fluid flow rate lower than the first fluid flow rate. The flow restrictor cartridge includes a receiver and a compact flow restrictor. The compact flow restrictor is received by the receiver. The compact flow restrictor is configured to facilitate the reduction from the first fluid flow rate to the second fluid flow rate.
