Abstract: An example vacuum-assisted toilet includes a toilet bowl including an outlet. The outlet of the toilet bowl is fluidly coupled to a first flush valve, for example, using a first pipe. The first flush valve is fluidly coupled to a second flush valve that is positioned downstream from the first flush valve. For example, the first flush valve may be fluidly coupled to the second flush valve using a second pipe. The second flush valve is fluidly coupled to a vacuum source. The vacuum source may include, for example, a holding tank having a vacuum pressure therein, a vacuum pump, or any other suitable vacuum source.

Abstract: A side-opening sleeve valve having an inner cylindrical barrel with a shaped opening through the wall, an outer cylindrical barrel having shaped opening through the wall, where the barrels are co-annular and rotatable, and a means for rotating the inner barrel relative to the outer barrel between a first open position where the shaped openings overlap to form a side opening into the sleeve valve, and a second closed position where the shaped openings do not overlap. A side-opening valve is used in pigging fluid flush system for a water-less toilet, where a toilet bowl empties into the side opening of the side-opening valve when opened. When the side-opening valve is closed, a pig cleaning system pushes the waste in the side-opening valve to a sewage system.

Abstract: A toilet has an electronic flush assembly operable in either a short or long flush sequence selectable by a user. The long flush sequence includes a pre-rinse cycle and a rinse cycle in which the a supply valve and a flush valve are both opened and closed twice, once each first during the pre-rinse cycle and again during a subsequent rinse cycle. The rim supply valve and the flush valve are opened during the pre-rinse and rinse cycles but are closed at the start and end of each cycle. An electronic control controls operation of the valves as well as water supply control components. Level sensors can also be included to provide feedback to the controller, for example, to prevent overflow conditions.

Abstract: A toilet and toilet system suitable for a boat, recreational vehicle, bus or the like is operated via a microprocessor controller to effect a convenient and efficient operation. The toilet includes a base assembly having an electrically-operated flush valve that opens and closes a passage to a waste receiving area. A flush lever assembly has a flush lever displaceable from a neutral position toward one of a “flush” position and an “add water” position. In this context, the flush lever initiates a flush cycle in the “flush” position and initiates an add water cycle in the “add water” position. The controller communicates with a water inlet valve, the flush valve and the flush lever assembly. In operation, the controller opens and closes the water inlet valve and controls a position of the flush valve in accordance with a position of the flush lever.

Abstract: A mechanism for multiplying rotation. The mechanism includes two armatures of differing lengths which rotate about different centers of rotation. The armatures are coupled together such that a rotation of one armature will produce a multiplied rotation in the other armature. The multiplying mechanism has particular application with a valve assembly of the type used in self-contained sanitary systems of recreational vehicles. The valve assembly includes a seal element having a sealing lip directed toward generally inward and downward of a fill opening a valve blade in the holding tank. The sealing lip terminates in a downwardly and outwardly oriented flange. The valve blade is actuatable through two movements. The first movement moves the valve blade generally vertically into and out of engagement with the seal element. The second movement moves the valve blade generally horizontally to a position out of registry with the fill opening.

Abstract: A vacuum sewer arrangement comprises a valve controlled air inlet duct to let air into the vacuum sewer at a position downstream of the sewer valve. The sewer valve can then be closed immediately after the sewage has passed into the vacuum sewer, because the air required for the sewage transport is received from the air inlet duct. Hence, the amount of air that flows into the sewer through the sewer valve when the sewer valve opens is small, and when the sewer valve is closed, air flows through the air inlet duct into the sewer, which reduces the pressure difference acting on the sewer valve. These measures tend to considerably reduce the noise level. In the case of a vacuum toilet sewer arrangement, the noise level can be further reduced by providing the toilet bowl with a lid forming a substantially airtight and soundproof closure at the top of the bowl. The volume of air contained in the bowl may be too small for proper discharge of the sewage, in which case additional air can be provided through a separate tube. This tube may be connected to the air inlet duct upstream of its valve.

Abstract: A portable toilet of the type having two vertically stacked sections, the lower section (12) being a holding tank, and the upper section (14) including a toilet bowl (22), a water tank (26) for storage of water for flush purposes, and flush apparatus (32) for flushing the toilet bowl. Handles (78) and (80) are provided for separately carrying the lower section (12) and the upper section (14), the handles being arranged so that they form a unitary handle for carrying the toilet (10) without the need of a clasping mechanism for holding the sections together. An improved flush apparatus (32) including the flush bulb (84) is provided so that priming of the flushing system is unnecessary. A valve assembly (46) is mounted within the confines of the lower section (12) by providing a planar member (58) that is a part of the valve body (56) and can be inserted through an opening (72) in the top wall of the lower section (12) for attachment to the top wall within the holding tank.
