Rotary Slide Valve Segmentation for Flexible Fluid Connections
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing rotary slide valves lack flexibility in connecting individual inputs and outputs, restricting their application in thermal management systems and internal combustion engines, and are complex and costly to manufacture.
Innovation Solution
A rotary slide valve with a two-part semi-cylindrical housing and a channel system connecting fluid inlet and outlet openings, allowing for individual selection and control of valve slides, enabling a high degree of integration and modular functionality, reducing complexity and part count.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a central inlet supplies fluid to the entire valve chamber, then the valve chamber is flooded with medium, but this restricts flexibility in connecting individual inputs and outputs
Solution Approach 1:
The valve chamber is divided into multiple individual valve slide chambers, each with its own fluid supply connection. This segmentation allows independent control and flexible connection of individual inputs and outputs, eliminating the restriction of a centralized flooding system while maintaining manageable complexity through modular architecture.
2Adaptability or versatility
If multiple valve slides are arranged axially one behind the other, then individual outlets can be opened, but the device complexity increases
Solution Approach 1:
The valve body is segmented into multiple independently controllable valve slides arranged axially, each capable of being opened or closed separately. This allows flexible configuration of connection options while maintaining a compact axial arrangement that limits overall device complexity.
Solution Approach 2:
The valve slides are designed to be dynamically adjustable, allowing individual outlets to be opened or closed as needed. This dynamic control capability provides versatility in connection options while the modular design keeps the overall system complexity manageable.
3Manufacturing precision
If a rotary gear with worm and internal toothing is used to control valve slides, then precise positioning is achieved, but manufacturing complexity and costs increase
Solution Approach 1:
The control mechanism is segmented into modular components (worm gear, toothed rings, valve slides) that can be manufactured separately and assembled. This segmentation enables precise positioning through standardized gear mechanisms while reducing overall manufacturing complexity and costs compared to monolithic designs.
