Abstract: Vacuum toilet system (10) for efficient transport of waste material from a toilet bowl (14) to a collection station (via conduit 22) by means of differential pressure, comprising an actuator button (42), a discharge valve (24), a water valve (34), and a controller valve (28). The various valves are simple in construction and operate on the basis of pneumatic pressure. The system (10) is compact enough to fit into the cabinet of a conventional toilet fixture.

Abstract: An apparatus for preventing waterlogging of the sensor and controller valves used to regulate operation of the vacuum interface valve in a sump vented vacuum sewerage system. A float valve operates in accordance with the sewage level in a sump pit and communicates atmospheric pressure to the sensor and controller valves while the sewage level is below a predetermined limit, but closes passage of sewage therethrough once the sewage level exceeds the predetermined limit. A pressure-relief valve may also be operatively connected to the float valve that vents excessive hydrostatic pressure buildups in the sump pit to the atmosphere.

Abstract: An apparatus for preventing waterlogging of the sensor and controller valves used to regulate operation of the vacuum interface valve (162) in a sump- vented vacuum sewerage system. A float valve (250) operates in accordance wi th the sewage level in a sump pit (154) and communicates atmospheric pressure t o the sensor and controller valves while the sewage level is below a predetermined limit, but closes passage of sewage therethrough once the sewa ge level exceeds the predetermined limit. A pressure-relief valve may also be operatively connected to the float valve (250) that vents excessive hydrostatic pressure buildups in the sump pit (154) to the atmosphere.

Abstract: A compact, self-contained, portable vacuum toilet system having a sump for collecting waste liquids by means of gravity, a differential pressure-operated discharge valve for regulating withdrawal of waste liquids from the holding sump for transport to a vacuum collection tank during a transport cycle, differential pressure-operated sensor and controller valves for regulating operation of the discharge valve in response to a hydrostatic pressure condition inside the holding sump, and a push button-operated water valve for adding water to the toilet bowl during and immediately after a flush cycle. A sink and its own push button-operated water valve may also be provided.

Abstract: Se proporciona una red de alcantarillado al vacío con un colector de fango (12) y una estación recolectora (20) conectada por un conducto (22). Cuando una válvula de interconexión al vacío (30) se abre, las aguas residuales son transportadas del colector de fango a la estación recolectora por un diferencial de presión. Un sensor de posición de válvula (40) asociado con la válvula se detecta mediante un sistema de monitorización de válvula. El sistema de monitorización está adaptado para transmitir una señal inalámbrica del estado de la válvula. Una computadora recibe la señal de emisión y le notifica a un operador sobre el estado de la válvula.

Abstract: An integral, vacuum operated, package system for collecting and transporting waste liquids from, e.g., a defrosted freezer, sink, bathtub, or water fountain, to a vacuum transport conduit connected to a vacuum collection station. The package system preferably includes a collection sump, sensor valve, controller valve, vacuum volume, and vacuum valve, which operatively communicate with each other by means of applied differential pressure to withdraw waste liquid from the collection sump and pass it through an opened vacuum valve during a transport cycle. The package system is compact, portable, and easily installed and maintained, and may be concealed in most applications, since it requires a mere volume generally measuring 12''x8''x31/2.
