    • An elbow fluid flow valve exhibiting reduced flow loss and including a body having a specified shape and size and defining a short radius associated with an elbow shaped fluid passageway characterized by a first fluid flow inlet and a second fluid flow outlet. A cover secures over the valve body, and such that a generally sleeve shaped annulus is defined therebetween. A light-weight and linearly translatable sleeve is mounted exteriorly of the valve body and within the intermediately defined annulus. The sleeve is operable to be displaced between a first location permitting fluid flow to the outlet and a second location interrupting fluid flow. A control element is operably connected to a pair of access ports, in turn communicated with one or a pair of interior regions in communication with locations of the displaceable sleeve and, upon experiencing at least one of a pressure and flow disparity between valve inlet and outlet, facilitates displacement of the sleeve to the second (flow interrupting) location.

    • The present subject matter relates to a fluid control system (20, 20', 20'') installed in a flow path of a fluid. The fluid control system (20, 20', 20'') includes a first orifice (30) to provide a first pass-area to the fluid, a first closing element (32) to vary the first pass-area, a second orifice (34), configured in the first closing element (32), to provide a second pass-area to the fluid, a second closing element (36) to vary the second pass-area, and a single actuating shaft (42). The second orifice (34) is smaller than the first orifice (30). The first orifice (30) includes a first seat (38) for the first closing element (32) to rest and close the first orifice (30), and the second orifice (34) includes a second seat (40) for the second closing element (36) to rest and close the second orifice (34). The first pass-area and the second pass-area are varied by the first closing element (32) and the second closing element (36) through movements of the single actuating shaft (42).

    • A liquid metering device that dispenses liquid into an adjacent reservoir at a precise ratio relative to the total volume of the adjacent reservoir as the reservoir is filled with liquid. The hydrostatic dispensing system includes an additive reservoir, a calibrated dispensing vessel, a hydrostatic pressure chamber, and a three-way valve that passively arms and dis-arms the system. The precise dispensing of liquid by a calibrated dispensing vessel into the adjacent reservoir is accomplished entirely through the management and arrangement of hydrostatic pressure creating a liquid piston generated by the addition of liquid to the adjacent reservoir and its subsequent application to the liquid in the calibrated vertical column that displaces the calibrated volume of liquid into the reservoir at the same rate that liquid is added to the reservoir.
    • 液体计量装置,当储存器充满液体时,液体计量装置以相对于相邻储存器的总体积的精确比例将液体分配到相邻储存器中。 静液分配系统包括添加剂储存器,校准的分配容器,静水压力室和被动地武器和系统的三通阀。 通过校准的分配容器将精确的液体分配到相邻的储存器中完全通过流体静力压力的管理和布置实现,从而产生液体活塞,该液体活塞通过将液体添加到相邻的储存器中而产生,并且随后在校准的垂直 柱将校准体积的液体以与添加到储存器中的液体相同的速率移动到储存器中。
