Abstract: A toilet includes a bowl portion, a rim portion, and a reservoir. The bowl portion defines a bowl cavity that is in fluid connection with a trapway. The bowl cavity is configured to hold a volume of water to provide a water seal for the trapway. The rim portion extends about an upper portion of the bowl portion. The rim portion defines an internal rim cavity that extends about an upper portion of the rim portion and a plurality of apertures that extend from the internal rim cavity and through a sidewall of the rim portion to direct water from the internal rim cavity to the bowl cavity. The reservoir is in fluid communication with the internal rim cavity and the bowl cavity and configured to receive a supply of pressurized water from a water source and direct at least a portion of the pressurized water to the internal rim cavity.

Abstract: A pressure toilet has a trapway providing “as needed” (bulk dependent) siphon assist. During normal liquid waste or low bulk flushing, no siphon is formed in the trapway, and the water and light waste in the bowl are evacuated solely under the force of the pressurized jet of water. A large volume near or just downstream from the dam is provided to accommodate the blow out from the water jet. Only upon reaching a threshold concentration of bulk waste material in the down leg does the trapway draw a siphon. A horizontal baffle at the lower part of the down leg assists in the accumulation of bulk material of sufficient concentration to establish a siphon in the trapway.

Abstract: A urinal is disclosed as having a spreader assembly. The spreader assembly includes a spreader body that may be mounted to the urinal, and a spreader mat. The spreader mat includes a series of spray holes. The spreader body is connected to a water supply, and a perimeter of the spreader mat is sealed to the spreader body. Each spray hole of the spreader mat is oriented to direct water onto a particular area of the urinal, when water is supplied to flush the urinal.

Abstract: A toilet trip lever assembly provides a lever arm that extends in the tank perpendicular to the tank wall. As an outer handle is rotated, it drives a stem, which in turn drives an arm inside the tank that extends parallel to the tank wall, which pushes down an end of a lever. A support holds the lever such that downward movement of that end of the lever drives the opposite end of the lever up. The opposite end of the lever is connected to a linkage to a flush valve.
