Integrated Pressure Relief Valve in Filter Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing filter assemblies face issues with excessive fluid pressure damaging the filter medium, requiring separate pressure relief valves and complex fitting operations.
Innovation Solution
Incorporating a pressure-limiting means, such as a pressure relief valve with a spring-actuated valve closure member, directly between the fluid inlet and filter medium to regulate pressure and prevent damage, eliminating the need for a separate upstream valve.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a separate pressure relief valve is installed upstream of the filter inlet, then the filter medium is protected from excessive pressure, but the device complexity and installation complexity increase
Solution Approach 1:
The pressure relief valve is integrated directly into the filter assembly housing, combining two separate functions (pressure relief and filtration) into a single unified device. This eliminates the need for a separate upstream pressure relief valve installation while maintaining filter medium protection.
Solution Approach 2:
The filter assembly housing serves multiple functions: it houses the filter medium, provides structural support, and incorporates the pressure relief valve mechanism. This multi-functionality reduces the overall number of components needed in the system.
2Reliability
If a separate pressure relief valve is installed upstream of the filter inlet, then the filter medium is protected from excessive pressure, but the ease of operation and installation are reduced

3Ease of operation
If the filter assembly includes integrated pressure-limiting means, then the ease of installation is improved, but the device complexity increases

Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Ensures the filter medium is protected from excessive pressure, simplifying the installation process by integrating pressure regulation within the filter assembly, thereby enhancing reliability and ease of use.
Implementation Method 1
The pressure relief valve preferably comprises spring means engaged with the valve closure member for urging the valve closure member in a preferred direction.
Implementation Method 2
when the valve closure member is disengaged from the valve seat, fluid pressure is applied to a first surface of the valve closure member which produces a first force urging the valve closure member in a first direction and to a second surface of the valve closure member which produces a second force urging the valve closure member in a second direction opposite to the first direction.

AI summary
A filter assembly comprises a fluid inlet, a fluid outlet and a filter medium for receipt of fluid from the fluid inlet and for supplying filtered fluid to the fluid outlet, the filter medium being located between the fluid inlet and the fluid outlet. The assembly further comprises pressure-limiting means, such as a pressure-relieving valve, located between the fluid inlet and the filter medium.
