    • A water faucet assembly includes a faucet operatively connected to a water source, an energy storage element, and a valve in operative communication with the faucet and the water source to selectively permit water flow from the water source to the faucet. A light detector mechanism is configured to detect ambient light. A control mechanism is powered by the energy storage element and is in operative communication with the light detector mechanism and the valve. The control mechanism is configured to activate the valve to permit water flow from the water source to the faucet responsively to the level of ambient light detected by the light detector mechanism.
    • 水龙头组件包括可操作地连接到水源的水龙头,能量存储元件和与水龙头和水源可操作地连通的阀,以选择性地允许水从水源流到龙头。 光检测器机构被配置为检测环境光。 控制机构由能量存储元件供电,并与光检测器机构和阀门操作连通。 控制机构构造成启动阀门,以使水能够响应于由光检测器机构检测到的环境光的水平而从水源流到水龙头。

    • A metering valve includes a valve body with an inlet passage and an outlet passage defined therein, and a movable stem member disposed between the inlet passage and outlet passage. An inner sleeve member is configured within the valve body and has an inner diameter surface defining a chamber, the stem member being movable through the chamber. A piston assembly is disposed within the chamber and is configured with the stem member to move therewith. The piston assembly includes a sealing device which engages with the inner sleeve member inner diameter surface during movement of the piston assembly to the closed mode. A metering passage is defined through the stem member between a location above the sealing device to a location below the sealing device such that the rate of return of the piston assembly from the open mode to the close mode is dependent upon the size of the metering passage. At least one additional vent passage is defined from a location above the sealing device to a location below the sealing device in the closed mode. The vent passage includes at least one hole defined above the sealing device completely through the inner sleeve member, and at least a second hole defined below the sealing device completely through the inner sleeve member. The vent passage is only established upon the sealing device passing across the second hole in its movement from the open mode to the close mode.
    • 计量阀包括具有入口通道和限定在其中的出口通道的阀体,以及设置在入口通道和出口通道之间的可移动阀杆构件。 内套筒构件构造在阀体内并且具有限定腔室的内径表面,该杆构件可移动通过腔室。 活塞组件设置在室内并且构造成具有与其一起移动的杆构件。 活塞组件包括密封装置,其在活塞组件移动到关闭模式期间与内套筒构件内径表面接合。 计量通道通过阀杆构件限定在密封装置上方的位置到密封装置下方的位置,使得活塞组件从打开模式返回到关闭模式的速率取决于计量通道的尺寸 。 至少一个附加的通气通道从密封装置上方的位置限定在封闭模式下的密封装置下方的位置。 通气通道包括至少一个孔,其完全通过内部套筒构件限定在密封装置上方,以及至少第二孔,其完全通过内部套筒构件限定在密封装置下方。 排气通道仅建立在密封装置从打开模式到关闭模式的过程中穿过第二孔。

    • A swivel joint connecting articulable fluid conducting arm members of a plumbing assembly includes an inlet member matable with a first arm member and having an inlet fluid passage from the arm member to an inlet collar section. An outlet member is provided matable with a second arm member. The outlet member also defines an outlet fluid passage from the respective second arm member to an outlet member collar section. A fluid conducting shaft member is disposed through the inlet and outlet member collar sections so that the collar sections rotate about the longitudinal axis of the shaft. A bearing sleeve is concentric about the shaft so that the collar sections rotate about the bearing sleeve. Resilient sealing rings are disposed about the shaft adjacent the bearing sleeve so as to prevent leakage of fluid from the swivel joint. Upon axially compressing the sealing rings and the bearing sleeve together, the sealing rings radially expand thereby sealing against the collar sections.
    • 连接管道组件的铰接式流体传导臂构件的旋转接头包括可与第一臂构件配合并具有从臂构件到入口环部分的入口流体通道的入口构件。 出口构件可与第二臂构件配合。 出口构件还限定从相应的第二臂构件到出口构件套环部分的出口流体通道。 流体传导轴构件穿过入口和出口构件凸缘部分设置,使得套环部分围绕轴的纵向轴线旋转。 轴承套筒与轴同心,使得套环部分围绕轴承套筒旋转。 弹性密封圈围绕轴承设置在轴上,以防止流体从旋转接头泄漏。 在将密封环和轴承套筒轴向压缩在一起时,密封环径向膨胀,从而密封住套环部分。
