Abstract: Un aparato para prevenir la inundacion de agua de las válvulas de control y el sensor utilizado para regular la operacion de la válvula de interfase al vacío en un sistema de alcantarillado al vacío de descarga en sumidero. Una válvula de flotador opera de acuerdo con la palanca de aguas residuales en un pozo de sumidero, y comunica presion atmosférica al sensor y las válvulas de control mientras la palanca de aguas residuales está bajo un límite, predeterminado, pero cierra el paso por ahí de las aguas residuales una vez que la palanca de aguas residuales excede el límite predeterminado. Una válvula de recuperacion de presion también puede ser conectada operativamente a la válvula de flotador que descarga los residuos de presion hidroestática excesiva en el pozo de sumidero hacia la atmosfera.

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 with the sewage level in a sump pit (154) 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 (250) that vents excessive hydrostatic pressure buildups in the sump pit (154) to the atmosphere.

Abstract: An improved fuel transfer pump (10) is provided for relatively high flow transfer of fuel from one aircraft to another during an inflight refueling procedure, wherein the fuel transfer pump (10) includes a jet-type scavenge pump (12) for evacuating residual fuel from a fuel line (14) or manifold (15). The scavenge pump (12) comprises a venturi element (56) connected along a recirculation conduit (48) through which a small fuel flow is diverted from the high pressure discharge side of the fuel transfer pump (10) for return to the fuel tank (20). The recirculation fuel flow induces a vacuum in a suction throat of the venturi element (56), and this vacuum is coupled by a suction line (58) to evacuate residual fuel from the fuel line (14) or manifold (15) to the fuel tank (20). A flow baffle (62) is mounted along the recirculation conduit (48) downstream from the venturi element (56) to ensure flooding and priming of the scavenge pump (12).

Abstract: A vacuum sewer system and a method of operating such system is disclosed. The system includes a sewage holding tank (16A-D) and a lateral flow line (24A-D) and a vacuum valve (18A-D) associated with the holding tank (16A-D) for permitting a quantity of wastewater to be drawn out of the holding tank (16A-D) by a vacuum environment. The wastewater is drawn through the lateral flow line (24A-D) and a main pipeline (30) to a desired collection location (38). A plurality of air inlet valves (32A-H) are arranged at spaced locations along the main pipeline (30) for facilitating the flow of wastewater through the lateral flow line (24A-D) so that a large volume of the wastewater can flow through the lateral flow line (24A-D) in a given time.
