Hydraulic Valve Adjustable Locking Catch Contours
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hydraulic valves require a separate, constantly adjustable diaphragm to adjust volume flow, which is complex and space-consuming.
Innovation Solution
The hydraulic valve features constantly adjustable catch contours on the sliding control member, allowing the free cross-sectional surface area of the diaphragm to be adjusted by rotating the member, eliminating the need for a separate adjustable diaphragm and optimizing space usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a separate, constantly adjustable diaphragm is used to adjust volume flow in catch positions, then volume flow adjustment is achieved, but device complexity increases and space requirements increase
Solution Approach 1:
The patent combines the volume flow adjustment function with the existing catch position locking mechanism by making the catch contours constantly adjustable. This integration eliminates the need for a separate adjustable diaphragm, thereby reducing device complexity while maintaining volume flow adjustment capability in catch positions
Solution Approach 2:
The constantly adjustable catch contours serve dual functions: they provide positive locking in catch positions and simultaneously control the volume flow through the diaphragm. This multi-functionality reduces the number of separate components needed, addressing the complexity issue while preserving adaptability
2Adaptability or versatility
If a separate, constantly adjustable diaphragm is used to adjust volume flow, then volume flow adjustment is achieved, but space requirements increase
Solution Approach 1:
The patent merges the volume flow control function into the existing catch contour structure, eliminating the need for additional space-consuming components. The catch contours themselves are made constantly adjustable to control diaphragm position and thus volume flow, reducing overall valve space requirements
3Adaptability or versatility
If catch contours are made constantly adjustable to control diaphragm position, then volume flow adjustment in catch positions is achieved, but manufacturing complexity increases
Solution Approach 1:
The patent introduces constant adjustability to the catch contours through a threading mechanism, allowing them to be dynamically repositioned along the longitudinal axis. This dynamic feature enables volume flow adjustment while using standard manufacturing techniques like threading, which balances manufacturing complexity with functional adaptability

AI summary
A hydraulic valve includes a sliding control member that delimits at least one constantly adjustable diaphragm. The sliding control member is configured to be moved in the direction of a longitudinal axis. The hydraulic valve further includes a locking device with a locking member that is configured to be moved counter to the force of a first spring transversely relative to the longitudinal axis. The hydraulic valve further includes at least one catch contour in which the locking member is configured to be engaged in such a positive-locking manner that the sliding control member is releasably retained in a catch position that is associated with the respective catch contour. The position of at least one catch contour is constantly adjustable in such a manner that the free cross-sectional surface-area of the at least one diaphragm is constantly adjustable in the associated catch position.
