  • Patent number: 9726159
    Abstract: An arrangement for throttling a fluid flow includes a throttle element arranged so as to influence a flow cross section in a fluid duct. The throttle element has a resiliently elastic disc-shaped basic body which is arranged with a top side and a bottom side between at least two supports in the fluid duct. The body is arranged in such a way that the flow cross section can be variably adjusted as a function of a pressure difference between the top side and the bottom side of the resiliently elastic disc-shaped basic body. At least one support bears against the top side of the resiliently elastic disc-shaped basic body, and at least one support bears against the bottom side of the resiliently elastic disc-shaped basic body.

  • Patent number: 9683354
    Abstract: The present invention relates to apparatuses, systems, and methods that manage the flow of fluids, such as, for example, water, through pipes. Specifically, the apparatuses of the present invention creates a backward pressure in fluid traversing a pipe when the fluid meets a spring loaded poppet valve, wherein the backward pressure within the pipe provides compression to the fluid effectively compressing entrapped gas bubbles within the fluid. The pressure in front of the poppet valve builds and moves the poppet valve away from a seat allowing the fluid with compressed gas bubbles to flow therefrom, which provides more accurate water meter measurements because less gas is being considered in said measurements. Moreover, the apparatuses of the present invention provide backflow prevention. Systems and methods for managing fluids are further provided.
