Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing coaxial valves in filling adapters require multiple deflections of the media line, leading to increased size, complexity, and manufacturing costs due to unfavorable flow properties, which negatively impact handling and efficiency.
Innovation Solution
A coaxial valve design featuring a flow contour that transitions from parallel to perpendicular to the longitudinal axis, utilizing a circular cone-shaped seat seal for a single 90° deflection, reducing the number of deflections and simplifying the structure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple deflections of the media line are used to maintain axial flow direction, then the valve can maintain back-pressure tightness, but the valve size increases and structure becomes more complicated
Solution Approach 1:
The valve body is segmented into distinct functional zones: an inlet section with parallel flow contour, a transition section with the circular cone-shaped seat seal, and an outlet section with perpendicular flow contour. This segmentation allows each section to perform its specific function optimally while reducing overall complexity
Solution Approach 2:
The invention introduces a dimensional transition in the flow path by changing from parallel to perpendicular orientation relative to the longitudinal axis. The circular cone-shaped seat seal enables this dimensional change, allowing the flow to deflect 90° in a single controlled location rather than requiring multiple deflections
2Reliability
If multiple deflections of the media line are implemented, then axial flow direction is maintained, but the valve size and weight increase
Solution Approach 1:
Multiple deflection functions are merged into a single circular cone-shaped seat seal structure. This consolidated design achieves the same flow direction control that previously required multiple separate components, thereby reducing overall valve weight
3Reliability
If multiple deflections are used in the valve design, then proper flow direction is achieved, but manufacturing costs increase
Solution Approach 1:
The complex multiple-deflection structure is extracted and replaced with a single circular cone-shaped seat seal feature. This extraction simplifies the manufacturing process by eliminating the need to produce and assemble multiple deflection components, thereby reducing manufacturing costs
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This design enhances flow properties, reduces the adapter's size, weight, and production costs, improving handling and efficiency by eliminating multiple deflections and simplifying the coaxial valve construction.
Implementation Method 1
a circular cone-shaped impact surface is designed as a seat seal for the control tube of the coaxial valve. The apex of the cone of this impact surface is aligned with the central longitudinal axis of the flow contour running parallel to the longitudinal axis of the valve. At the same time, this circular cone apex runs out in the plane in which the central longitudinal axis of the flow contour running at right angles to the longitudinal axis of the valve is configured.
Implementation Method 2
In the coaxial valves that have been standard up to now, the control tube is pressed onto the seat seal by a piston using compressed air when it is closed. As a result, the control tube is closed by this seat seal and the medium is blocked. By switching the compressed air to the other pressure chamber of the piston, the control tube is moved away from the seat seal so that the flow is now released.

AI summary
The invention relates to a filling adapter for a container (2) to be filled with media (for example, oils, gases, cooling agents, and the like), in particular for an initial filling of a container with operating substances on assembly lines for the production of motor vehicles, wherein the filling adapter is equipped with a hose packet (1), electrical, pneumatic, and hydraulic lines. The problem addressed by the invention is that of structurally altering a coaxial valve such that if used in such a filling adapter, better fluidic properties are achieved. Another problem addressed at the same time is that of reducing the overall size, the production costs, and the weight of the component. These problems are solved in that the filling adapter is equipped with a coaxial valve in the region of the adapter head (3) of the filling adapter, which coaxial valve, starting from the inlet cross section, is initially provided with a flow contour extending parallel to the longitudinal axis of the valve, which in the further flow course transitions into a flow contour extending at a right angle to the longitudinal axis of the valve to the outlet cross section.
