Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing shuttle valves are limited in their ability to achieve precise flow regulation and rapid complete opening/closing due to fixed coupling of rotational and translational movements, leading to increased wear and limited suitability for both rapid displacement and precise control applications.
Innovation Solution
A shuttle valve with a drive unit comprising separate first and second drives for rotational and linear movements, respectively, actuated by a control unit to allow for variable displacement curves, enabling precise control and reduced wear through customizable movement sequences.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single drive with fixed coupling of rotational and translational movements is used, then the device complexity is reduced, but the adaptability for different displacement curves is worsened
Solution Approach 1:
The drive system is segmented into two independent drives: a first drive for rotational movement and a second drive for translational movement. This segmentation allows each drive to be optimized for its specific function while enabling flexible combination of movement sequences through programmable control, resolving the contradiction between device complexity and adaptability.
2Device complexity
If rotational and translational movements are fixedly coupled, then the device complexity is reduced, but the precision of flow regulation is worsened
Solution Approach 1:
The movement control is made dynamic and programmable rather than fixed. The control unit can store and execute different displacement curves that define the relationship between rotational and translational movements, allowing precise flow regulation to be achieved by selecting appropriate movement sequences without increasing hardware complexity.
3Device complexity
If a single drive is used for both rotational and translational movements, then the device complexity is reduced, but the productivity for rapid opening/closing is worsened
Solution Approach 1:
By segmenting the drive system into independent rotational and translational drives, each drive can operate at optimal speeds for its function. The programmable control enables rapid sequential execution of rotational positioning followed by translational closing, achieving fast opening/closing cycles without the mechanical constraints of a single coupled drive.
4Adaptability or versatility
If precise flow regulation is implemented, then the adaptability is improved, but the device complexity increases
Solution Approach 1:
The control unit serves multiple functions: it coordinates the two drives, stores multiple displacement curves, and enables different operating modes (precise flow regulation, rapid opening/closing). This multi-functionality achieves precise flow regulation capability without proportionally increasing hardware complexity, as the same control unit handles all regulatory tasks.

AI summary
The invention relates to a shuttle valve for interrupting a flow path (F), comprising a valve housing (1) having a valve seat (4) surrounding an opening (3) for the flow path (F). A valve disc (5) is arranged on a rotatably mounted shaft (6). By means of a drive unit (7), the valve disc (5) can be swiveled along a defined displacement curve (K1; K2; K3) from an opened position and leaving the flow path (F) unobstructed over the cross-section of the first opening (3) by a rotational movement about the pivot axis (8) of the shaft (6) and can be moved by a linear movement parallel to the pivot axis (8) in the direction of the valve seat (4) into a closed position so that the flow path (F) is sealed gas-tight by a sealing contact between the valve disc (5) and the valve seat (4). According to the invention, the drive unit (7) has a first drive (9a) for carrying out the rotational movement about the pivot axis (8) and a second drive (10a) for carrying out the linear movement parallel to the pivot axis (8). By means of a control unit (11), the first drive (9a) and the second drive (10a) can be actuated so that a variable displacement curve (K1; K2; K3) can be produced.
