Radial Vent Hole in Fluid Filter Outlet Socket
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fluid filters face issues with gas or air volume introduction, leading to flow-through disturbances and potential complete interruption, especially in critical applications like fuel filtration for internal combustion engines, due to the complexity and high cost of known filter elements that require significant mounting space.
Innovation Solution
A filter element with a radial vent hole in the fluid outlet socket allows for minimal mounting space and simple production, featuring a screening element to separate contaminants and a water separation device to prevent clogging, enabling efficient venting and reducing the risk of component damage downstream.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a venting unit with a flow passage through the end disc is used to discharge gases, then gas venting capability is improved, but the filter element requires larger mounting space and has complex construction
Solution Approach 1:
The invention extracts the venting function from the end disc structure and relocates it to the outlet socket. The outlet socket is provided with vent holes that directly communicate with the filtered fluid space, separating the venting function from the structural support function of the end disc. This simplifies the overall construction while maintaining effective gas discharge capability.
Solution Approach 2:
Instead of creating a complex three-dimensional flow passage through the end disc, the invention uses simple radial vent holes in the outlet socket. This dimensional simplification reduces manufacturing complexity while achieving the same venting function through a different spatial arrangement.
2Reliability
If a venting unit with flow passage through end disc is implemented, then gas discharge function is improved, but mounting space requirement increases
Solution Approach 1:
The invention merges the venting function with the existing outlet socket structure. Instead of adding a separate venting component that would increase mounting space, the vent holes are integrated into the outlet socket itself, utilizing existing space and reducing the overall filter element volume.
3Reliability
If existing venting structures are used, then gas venting is achieved, but production cost increases due to complex manufacturing
Solution Approach 1:
The outlet socket is segmented with multiple simple vent holes rather than requiring a complex continuous flow passage. This segmentation allows for simpler manufacturing processes such as drilling or punching operations, reducing production cost while maintaining effective venting through multiple openings.
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
The solution effectively vents gases, prevents flow interruptions, and minimizes component damage by using a radial vent hole and screening element, allowing for efficient operation in tight spaces with reduced production costs and extended filter life.
Implementation Method 1
Due to the compressibility or expansion capability of the introduced gas or of the introduced air, flow-through disturbances and, in an extreme case, a complete interruption of the fluid column may occur within the fluid filter

AI summary
A filter element for filtering a fluid is provided with a first end disc and a second end disc. An annularly arranged filter medium is held between the first and second end discs. The filter medium can be flowed through by a fluid to be filtered in a radial direction relative to a longitudinal axis of the filter element from an exterior of the filter element to an interior of the filter element. A fluid outlet socket is connected to the filter medium and extends away from the filter medium in an axial direction past the first end disc. The fluid outlet socket is provided with a wall and at least one vent hole extending through the wall in the radial direction. A fluid filter is provided with a filter housing and with the afore described filter element that is arranged in the filter housing.
