Pressure Reducer Guide Means Arrangement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pressure reducers for fluid lines have complex designs and significant installation heights, requiring additional ports and special housings, which complicate the guidance of sealing, equalization, and connecting components, leading to inefficiencies in compactness and operational reliability.
Innovation Solution
The guide means are arranged between the sealing piston and the equalization piston, allowing for optimal guidance and a compact design, with radial wings protruding from the connecting means to contact the valve seat, and a sleeve with identical diameters at the valve seat and equalization piston regions to compensate forces, ensuring effective torque elimination and pressure equalization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If guide means are arranged beyond the sealing piston in relation to the equalization piston, then the arrangement can be guided, but the installation height increases and compactness is reduced
Solution Approach 1:
The guide means are repositioned from a location beyond the sealing piston to a location in the region of the valve seat between the sealing piston and equalization piston. This spatial reconfiguration in a different dimensional arrangement allows effective guidance while reducing the axial installation height of the pressure reducer.
2Reliability
If a funnel is used as guide means, then the arrangement can be guided, but the funnel requires adequate stiffness and adds structural complexity
Solution Approach 1:
The guide function is extracted from a separate funnel structure and integrated directly into the connecting means that already connects the sealing piston and equalization piston. This eliminates the need for a distinct funnel component and its associated stiffness requirements, simplifying the overall structure while maintaining guidance functionality.
3Length of stationary object
If guide means are arranged in the region of the valve seat between the sealing piston and equalization piston, then compactness is improved and torque is eliminated, but the guide means must contact the valve seat and abutting region
Solution Approach 1:
The guide means are merged with the connecting means, forming an integrated structure. This combination allows the guide function to be performed at the valve seat region without requiring separate guiding components, achieving compactness while the integrated structure naturally handles the contact and guidance requirements during operation.

AI summary
A pressure reducer for fluid lines, with a sealing piston (70, 110) as stop element, with an equalization piston (20a, 190) as a means for pressure equalization, with a single-part or multi-part connecting means (20b, 90, 200) by which the sealing piston (70, 110) and the equalization piston (20a, 190) are rigidly connected with one another, with a valve seat, in conjunction of which the sealing piston (70, 110) defines a flow-through opening, against which the sealing piston (17, 110) seals when the valve is closed and which the connecting means (20b, 90, 200) penetrates, and with guide means (20c, 210) which are directly or indirectly rigidly coupled with the connecting means and guide an arrangement composed of at least the equalization piston (20a, 190), connecting means (20b, 90, 200) and sealing piston (70, 110) in each operating position, wherein the guide means (20c, 210) are arranged in the region of the valve seat between the sealing piston (70, 110) and the equalization piston (20a, 190).
