Abstract: A vacuum toilet system comprises a toilet bowl having a cover mounted for movement relative to the toilet bowl between an open position and a closed position, the cover being in at least partially sealing relation with the rim when in the closed position. A liquid supply opening is provided for introducing liquid into the toilet bowl when the cover is in the closed position. A discharge valve connects the outlet opening of the toilet bowl to a sewer pipe, in which a partial vacuum can be established. A reservoir has an inlet opening for receiving rinse liquid and an outlet opening in communication with the liquid supply opening. The inlet opening of the reservoir is exposed to substantially the same pressure as the liquid supply opening when the toilet bowl cover is in the open position and the discharge valve is closed. Rinse liquid is drawn from the reservoir into the toilet bowl by way of the liquid supply opening when the discharge valve is open and the cover is in the closed position.

Abstract: A lavatory system suitable for use on a commercial passenger aircraft includes at least one toilet bowl for receiving waste and a waste-holding tank in fluid communication with said toilet bowl for receiving waste from said toilet bowl. The waste-holding tank is kept at a pressure less than the ambient pressure surrounding the toilet bowl so that waste from the toilet bowl is drawn to the tank by the difference in pressure. A flush valve is provided in the drain line between the toilet bowl and the waste-holding tank and is selectively operable to pass the toilet bowl contents into the waste-holding tank. Water from the potable water supply system is provided to the toilet bowl to wash the sides of the toilet bowl and to assist in moving the waste material to the drain line. A water inlet valve is provided to selectively control the introduction of water into the toilet bowl and preferably the water inlet valve and flush valve are operated in a timed sequence by actuation of a single flushing switch. The water is introduced into the toilet bowl through a nozzle ring which directs the flow of the water onto the interior of the toilet bowl in coherent streams and is matched to the toilet bowl configuration in such a manner that a minimal amount of water is utilized per flush. The range of water utilized is in the neighborhood of six to ten ounces per flush and the water is directed onto the sides of the bowl in a plurality of streams such that each directed stream is dedicated to rinse a particular area of the toilet bowl with the streams of water coalescing to form a substantially continuous sheet of water on substantially all parts of the interior surface of the toilet bowl to completely flush the toilet bowl of waste material.

Abstract: A quiet water closet rim and a method for venting air from a rim cavity of a water closet. The rim has a horizontally oriented annular cavity and is selectively supplied with pressurized water by a flush mechanism. A series of perforations in the rim permits the pressurized water within the rim cavity to exit the rim in the form of a spray. The rim is also provided with a vent passageway having an inlet open into an upper portion of the cavity and an outlet open into the atmosphere. As pressurized water fills the cavity, a portion of the air within the upper portion of the cavity is vented through the vent passageway.

Abstract: A device is described which, when inserted under the rim of a toilet bowl in contact with the side wall thereof, uniformly distributes water over the surface of the bowl walls. This aids flushing material from the toilet. In many types of toilets, this also reduces the quantity of water required for each flushing operation. The device is flexible whereby installation and removal are facilitated in any shape of conventional toilet bowl.
