Solenoid Valve Pressure Resistance via Integrated Insert
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional solenoid valve devices used in antilock braking systems and electronic stability programs are not fully capable of sealing off pressure forces in both directions, leading to increased manufacturing costs and complex assembly processes.
Innovation Solution
A solenoid valve device with pressure means that press the valve insert against the valve receiving device, creating a frictional bearing contact and achieving high pressure resistance in both directions without additional components, and optionally incorporating an axial filter and sealing element for enhanced sealing and filtering.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional solenoid valve devices use multiple individual components (valve lower part, plastic insert, nonreturn valve) to seal pressure forces, then sealing capability is improved, but device complexity and manufacturing cost increase
Solution Approach 1:
The patent combines multiple sealing functions (sealing element, nonreturn valve, pressure resistance) into a single integrated valve insert component. The valve insert includes a sealing element at its end and a nonreturn valve, eliminating the need for separate plastic inserts and nonreturn valves used in conventional devices. This merging reduces the number of components while maintaining comprehensive sealing capability in both directions.
2Reliability
If conventional solenoid valve devices use multiple individual components for sealing, then sealing capability is improved, but manufacturing cost and assembly time increase
Solution Approach 1:
The valve insert is manufactured as a single integrated component containing the sealing element, nonreturn valve, and valve core. This eliminates the need for assembling multiple separate components (valve lower part, plastic insert, nonreturn valve) as in conventional devices, thereby reducing both manufacturing cost and assembly time while maintaining comprehensive sealing capability.
3Stress or pressure
If pressure means is pressed into the valve insert, then pressure resistance in both directions is improved, but the valve insert dimensions must be precisely controlled
Solution Approach 1:
The patent introduces a pressure means (pressure element) as an intermediary component that is pressed into the valve insert. This pressure element mediates the transmission of pressure forces between the valve insert and the valve receiving device, enabling high pressure resistance in both directions. The pressure element's frictional bearing contact with the valve insert's outside wall provides the necessary force transmission while accommodating reasonable dimensional tolerances.
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 provides improved sealing and pressure resistance in both directions, reduces manufacturing costs and assembly complexity, and minimizes the overall height of the valve device while maintaining a reduced number of components.
Implementation Method 1
pressing the pressure means into the valve insert serves to press the valve insert against the valve receiving device and therefore affords a frictional bearing contact of the valve insert outside wall against the inside wall of the valve receiving device
Implementation Method 2
The sealing element, which is situated between the valve insert and the valve receiving device, leads to a further increase in the pressure resistance and sealing effect in both directions
Implementation Method 3
an axial filter is introduced axially between the valve receiving device and the valve insert

AI summary
A magnetic valve device includes a valve receiving device and a valve insert of a magnetic valve which is received in the valve receiving device. A high pressure resistance is obtained in one of the modes of embodiment. The magnetic valve device includes either a pressure mechanism configured to press the valve insert against the valve receiving element or a sealing element arranged in a notch in the valve insert or a sealing element arranged between an axial filter and the valve insert.
