Summary of the Inventive Concept

A novel application of air extraction technology to remove air bubbles from industrial fluid transmission systems, enabling improved efficiency, reliability, and safety in various industries.

Background and Problem Solved

The original patent, 'Intravenous tubing venting assembly', addressed the critical issue of air bubble removal in medical IV tubing. However, the limitations of the original design restrict its applicability to other industries. The new inventive concept adapts and expands this technology to tackle air bubble removal in industrial fluid transmission systems, such as wind turbines, fuel cell systems, fuel injector cleaning, and mechanical gearboxes.

Detailed Description of the Inventive Concept

The new inventive concept comprises an air extraction device installed in-line with the industrial fluid transmission line. The device features a venting valve that allows air bubbles to escape along a venting path while preventing fluid passage through the venting path. In specific embodiments, the air extraction device can be configured to release airlocks in the fluid flow, or include a ball valve to prevent rapidly-infused cleaning fluids from being forced into a branch tube. The device can be adapted for various industrial applications, including wind turbines, fuel cell systems, fuel injector cleaning, and mechanical gearboxes.

Novelty and Inventive Step

The new inventive concept introduces a novel application of air extraction technology to industrial fluid transmission systems, which is not obvious from the original patent. The inventive step lies in the adaptation of the original design to address the specific challenges of air bubble removal in industrial settings, resulting in a new and non-obvious solution.

Alternative Embodiments and Variations

Alternative embodiments of the inventive concept could include variations in the venting valve design, chamber materials, or fluid flow configurations to accommodate different industrial applications. For example, a modular design could allow for easy integration into existing fluid transmission systems, or the use of advanced materials could enhance the device's durability and performance.

Potential Commercial Applications and Market

The inventive concept has significant commercial potential in various industries, including wind energy, fuel cells, automotive, and mechanical engineering. The ability to efficiently remove air bubbles from industrial fluid transmission systems can lead to improved system reliability, reduced maintenance costs, and enhanced overall performance. The target market includes original equipment manufacturers, system integrators, and maintenance service providers in these industries.
