Hydraulic Vibration Damper Venting Layout for Tight Installation Space
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vibration dampers with hydraulic connections require a large installation space, making them unusable in certain vehicles due to space constraints.
Innovation Solution
The venting valve is hydraulically connected in parallel with the check valve, and the hydraulic connection includes a filling connection with a venting valve that can be opened independently of the check valve position, allowing for separate venting of the hydraulic system without affecting the vibration damper, thereby reducing space requirements and simplifying the installation process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the venting valve and check valve are connected in series as in prior art, then the hydraulic system can be vented through the vibration damper, but the installation space requirement increases and the venting process affects the vibration damper
Solution Approach 1:
The patent divides the venting function into two independent parts: the check valve remains integrated with the vibration damper while the venting valve is separated and positioned at the filling connection. This segmentation allows the venting operation to be performed independently without affecting the vibration damper, while also reducing the installation space required for the hydraulic connection components.
2Reliability
If separate individual valves are used for check valve and venting valve, then each valve can be optimized for its specific function, but the device complexity and installation space increase
Solution Approach 1:
The patent combines the venting valve with the filling connection structure, integrating the venting function into the existing filling infrastructure. This merging approach maintains the functional optimization of separate valves while reducing overall device complexity and eliminating the need for additional separate valve components and their associated mounting structures.
3Ease of manufacture
If pre-filled connection lines are used in the hydraulic system, then the initial setup is simplified, but the installation space requirement and system complexity increase
Solution Approach 1:
The patent extracts the venting function from the series connection and relocates it to the filling connection point. This allows the filling connection to serve dual purposes: filling the hydraulic system and venting air bubbles. By taking out the separate venting requirement, the system eliminates the need for pre-filled connection lines and extensive venting infrastructure, reducing installation space while maintaining ease of setup.
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
This configuration eliminates the need for pre-filled connection lines, enables efficient venting of the hydraulic system, and reduces installation space by combining the filling and venting functions, providing a significant time advantage and improved space utilization.
Implementation Method 1
the venting valve is hydraulically connected in parallel with the check valve, and the hydraulic connection has a filling connection that is outfitted with the venting valve, and the filling connection is opened independent from the position of the check valve
Implementation Method 2
Each hydraulic connection comprises a check valve and a venting valve. The check valve and the venting valve represent completely separate individual valves
Implementation Method 3
the valve body has a sealing flange that seals off a connection chamber with a wall of the hydraulic connection. No work medium can escape from the hydraulic connection even when the check valve is open to the maximum extent.

AI summary
A vibration damper with a hydraulic connection includes a check valve and a venting valve. The check valve and the venting valve can be actuated separately, and a hydraulic communication between the vibration damper and a connection opening of the hydraulic connection is switchable via the check valve. The venting valve is hydraulically connected in parallel with the check valve, and the hydraulic connection has a filling connection which is outfitted with the venting valve. The filling connection is opened independent from the position of the check valve and is closed by the venting valve.
