    摘要: A vacuum toilet system for a vehicle (such as a boat) has numerous advantages. A single pump with valves on opposite sides of it may be used as both the vacuum source and for discharging sewage from a holding tank. Two sets of multiple heads may be selectively connected to two pumps for emergency purposes. The vacuum toilet includes a sealing element with an integral movable valve engaging element including polytetrylflouroethylene and synthetic rubber, and at the same durometer (55-65). The initial passageway provided by movement of the valve with respect to the seal is disposed directly above the center line of an orifice. An anti-siphon valve assembly has a simple construction of a housing with parallel legs and anti-siphon air passage in alignment with one of the legs. A spray nozzle extends from the other legs of the anti-siphon valve assembly. The toilet funnel/orifice is universally connected to conduits. The vacuum tank is blow molded of plastic, has universal ports including one continuous from the tank walls so that no accumulation takes place in the tank. Longitudinal ribs along the tank provide for easy connection to a support. A vacuum sensor is mounted to one of the vacuum tank ports with fasteners disposed exteriorly of the tank, and without the need for an O-ring. The pump comprises a rolling diaphragm pump in a housing with a sump, and the stem from the pump is plastic with pegs that are staked or ultrasonically welded to the movable pump element. A powdered metal crank arm connects the pump stem to a drive motor, the crank arm being the fail-safe part of the pump.

    摘要翻译: 用于车辆(例如船)的真空马桶系统具有许多优点。 在其相对侧上具有阀的单个泵可用作真空源并用于从储存罐排放污水。 两组多个头可以选择性地连接到两个泵用于紧急目的。 真空马桶包括具有包括聚四氟乙烯和合成橡胶的整体可动阀接合元件的密封元件,并且在相同的硬度计(55-65)处。 通过阀门相对于密封件的运动提供的初始通道设置在孔口的中心线的正上方。 一个防虹吸阀组件具有简单的结构,其具有平行腿部和与其中一个腿对准的防虹吸空气通道的壳体。 喷嘴从防虹吸阀组件的另一个支腿延伸出来。 马桶漏斗/孔口通常连接到管道。 真空罐由塑料吹塑成型,具有通孔,包括一个与罐壁连续的通孔,使得罐中不会积聚。 沿着坦克的纵向肋条可方便地连接到支架上。 真空传感器安装在一个真空罐端口上,紧固件设置在罐外部,无需O形环。

    摘要: A flush valve assembly (10) for a water closet having a reservoir tank (12) with a discharge opening (15). The flush valve assembly (10) incorporates a spud (13) having a tubular body portion (14) which presents an annular groove (55) that extends peripherally of the body portion (14) in close proximity to its axially upper rim (88). The tubular body portion (14) is received in the discharge opening (15) of the tank (12). The radial groove (55) supports a cantilevered diaphragm (51) which extends radially outwardly therefrom. The spud (13) also includes a guide (35) having a vent tube (40) slidably received thereon. The guide (35) extends axially upwardly from the body portion (14) of the spud (13) to be positioned interiorly of the tank (12). The lower portion of the vent tube (40) presents a skirt (45) which extends outwardly and downwardly to define a circular valve seat (49) for selective, sealing engagement with the diaphragm (51). An anticavitation plate (75) is positioned interiorly of the skirt (45) and extends radially between the skirt (45) and the vent tube (40).
