Solution Overview
Problem
Existing pressure compensation devices in fluid-conducting systems face challenges with microbial pollution and inefficient water flow, leading to potential damage and contamination in plumbing and foodstuff supply installations, particularly when used as hydraulic shock absorbers and expansion vessels.
Innovation Solution
A pressure compensation device featuring a pressure container with an elastic diaphragm and a pressurized gas chamber, where a separately led pipe encircled by a hollow cylinder sieve facilitates forced flow through the container, reducing microbial growth and minimizing frictional losses, allowing independent positioning and operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a diaphragm with lining is used to prevent microbial growth, then microbial pollution is reduced, but static water volume remains and allows microbial growth during periods without pressure fluctuations
Solution Approach 1:
The patent implements continuous water flow through the pressure container by providing separate inlet and outlet openings that maintain constant movement of water, preventing stagnation and microbial growth even during periods without pressure fluctuations. This ensures the useful action of preventing microbial pollution continues without interruption.
Solution Approach 2:
The patent divides the water flow path into separate inlet and outlet channels within the pressure container, creating distinct flow paths that ensure continuous circulation. This segmentation prevents dead zones where water could stagnate and allows the system to maintain protective function continuously.
2Reliability
If the entire water flow is led through the expansion vessel, then water replacement is achieved, but pressure losses occur
Solution Approach 1:
The patent applies local quality by providing separate inlet and outlet openings positioned at specific locations on the pressure container. This localized flow arrangement enables effective water replacement through targeted flow paths without requiring the entire water stream to pass through the expansion vessel, thereby reducing pressure losses while maintaining replacement effectiveness.
3Reliability
If a complex connecting fixture with partition wall and orifice is used, then forced water replacement is achieved, but device complexity increases
Solution Approach 1:
The patent extracts the essential function of forced water replacement from the complex connecting fixture structure. By providing separate inlet and outlet openings directly on the pressure container, it achieves forced water replacement through simple pressure-driven flow without requiring partition walls, orifices, or complex valve mechanisms, thereby significantly reducing device complexity while maintaining replacement effectiveness.

AI summary
The invention relates to a pressure compensating device for fluid-conducting systems, with a pressure container (1) for the pressure compensation, an elastic diaphragm (3), which forms a cavity (5) for receiving the fluid, and a pressure chamber of gas (7) adjoining the cavity (5). The diaphragm (3) is connected via a connecting mount (15) to a connecting pipe (17) for the fluid. A pipe (21) for the fluid, led separately to the connecting pipe (17), extends via the connecting mount (15) into the cavity (5), while being concentrically encircled by a hollow cylinder (25) shaped like a sieve, which defines an annular space (27) and opens into an end piece (29), into which the pipe (21) opens. Moreover the end piece (29) features sieve-like perforations (31) for the fluid to flow out into the cavity (5). The separately led pipe (21) extends into the fluid-conducting system, while the connecting pipe (17) for the fluid opens into the fluid-conducting system.
