Hydraulic Damping Device With Guide Element Flow Divider
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing damping devices for hydraulic supply circuits, such as silencers, are complex in design and do not efficiently manage pressure surges due to their reliance on separate damping tubes and lack of effective flow guidance within the fluid receiving space.
Innovation Solution
A damping device with a guide element integrated into the cover part that protrudes from the boundary wall, forming a flow divider within the disk-like fluid receiving space, which accelerates fluid flow and enhances damping efficiency without increasing flow resistance, and a sealing mechanism to ensure pressure resistance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a damping tube with openings is used in traditional damping devices, then the device can dampen pressure pulsations, but the design becomes complex and the flow velocity distribution becomes unfavorable for damping efficiency
Solution Approach 1:
The invention extracts and eliminates the damping tube component from the traditional damping device design. Instead of using a damping tube with openings, the patent uses a fluid receiving chamber with a free flow cross-section that extends in at least one direction transverse to the flow direction, allowing direct fluid flow from inlet to outlet without the complex tubular structure with multiple openings.
Solution Approach 2:
The invention transitions from a one-dimensional flow path through a damping tube to a three-dimensional fluid receiving chamber that extends in directions transverse to the flow direction. This dimensional expansion creates favorable flow velocity distribution for damping efficiency while simplifying the overall design.
2Reliability
If the fluid receiving chamber extends transversely to the flow direction, then damping efficiency improves through better flow velocity distribution, but flow resistance may increase
Solution Approach 1:
The invention applies local quality by creating a free flow cross-section in specific regions of the fluid receiving chamber that extends transversely to the flow direction. This localized expansion in certain areas promotes favorable flow velocity distribution for damping while maintaining efficient flow paths to minimize overall flow resistance.
