Solution Overview

Problem

Existing multi-way fluid valves lack the ability to independently control fluid flows and are costly to produce, particularly in applications like vehicle cooling systems where precise fluid management is required.

Innovation Solution

A multi-way fluid valve with a seal featuring elastically deformable anchoring sections for dynamic sealing with the valve housing and a statically sealing flange-like section for the valve body, allowing for independent control of fluid flows between valve chambers based on the valve body's position, using a combination of spring-like anchoring elements and a connecting piece for enhanced sealing efficacy.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a multi-way fluid valve uses a conventional seal design, then the structure is simple, but it cannot independently control fluid flows between different valve chambers

Engineering Contradiction:
Improveindependent fluid flow controlVSAvoidseal structure
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The seal is divided into multiple functionally independent sealing sections (first sealing section with first sealing surface, second sealing section with second sealing surface, and third sealing section with third sealing surface). Each sealing section can independently seal against different valve body surfaces, enabling independent control of fluid flows between different valve chambers while maintaining a unified seal structure.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Different sealing sections of the seal are designed with different local properties - each having specific sealing surfaces oriented in different directions to interact with different valve body surfaces. This local differentiation allows the single seal component to provide multiple independent sealing functions for controlling fluid flows in different directions.

Inventive Principle:
Principle #3Local quality

2Reliability

If the seal uses a rigid structure, then manufacturing is easy, but it cannot adapt to pressure conditions and maintain sealing

Engineering Contradiction:
Improvesealing under pressureVSAvoidseal structure
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

The seal is designed with elastic material properties that allow it to dynamically adapt to pressure conditions. The sealing sections can deform elastically under fluid pressure to maintain contact with the valve body sealing surfaces, ensuring reliable sealing. The dynamic adaptation is enabled by the elastic nature of the seal material while maintaining a relatively simple manufactured structure.

Inventive Principle:
Principle #15Dynamics

AI summary

A seal 26, 28 is proposed for use in a fluid valve 2 and for dividing a valve chamber between two adjacent ports 10, 12, 14, 16 of the fluid valve 2, in which an adjustable valve body 18 of the fluid valve 2 is arranged. The seal 26, 28 divides the valve chamber, which is formed by a valve housing 4, 6 and the adjustable valve body 18, into a first valve chamber V1 and a second valve chamber V2, depending on the position of the valve body 18, in order to prevent the flow of fluid between the first valve chamber V1 and the second valve chamber V2 depending on the position of the valve body 18.The seal 26, 28 has a valve housing-side, elastically deformable anchoring section 28VG for insertion into a groove-shaped valve housing recess 7 and for dynamic sealing against the valve housing recess 7, as well as a valve body-side section 28VK for static sealing against the valve body 18. A sealing arrangement with such a seal and a multi-way fluid valve with such a sealing arrangement are also proposed.
