Hydraulic Accumulator Separator Venting for Internal Pressure Relief
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hydraulic accumulators face safety risks due to the potential for high-pressure gas to escape and cause damage or injury, especially in the event of temperature increases or fires near the accumulator.
Innovation Solution
The bursting device is integrated into the separating element within the hydraulic accumulator, ensuring that in the event of failure, the pressure is relieved internally and fragments remain contained, preventing gas from escaping into the surrounding area.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the bursting device is arranged outside the separating element, then the pressure relief function is effective, but parts of the bursting device may be dispersed into the surrounding area causing safety risks
Solution Approach 1:
The bursting device is extracted from the traditional external arrangement and integrated into the separating element itself. The separating element is designed with a bursting device receptacle that houses the bursting device, allowing it to be taken out from the hazardous external position and placed within the safe internal environment of the accumulator housing.
Solution Approach 2:
The bursting device is nested within the separating element structure. The separating element comprises a bursting device receptacle that receives and contains the bursting device, creating a nested configuration where the bursting device is housed inside the separating element, which itself is inside the accumulator housing. This nesting ensures that upon activation, all components remain contained within the accumulator housing.
2Reliability
If the bursting device is integrated into the separating element, then fragments remain contained, but the device complexity increases
Solution Approach 1:
The bursting device and separating element are merged into a single integrated component. The separating element is designed to include the bursting device receptacle as an integral part, combining two previously separate functions (separation and pressure relief) into one unified structure. This merging reduces the number of separate components and simplifies the overall system architecture.

Function Achieved in This Case
This solution effectively prevents the dispersion of bursting device fragments and high-pressure gas into the environment, ensuring safety by maintaining pressure relief within the accumulator housing and avoiding potential hazards.
Implementation Method 1
a bursting device for reducing an inadmissibly high pressure in the accumulator housing
Implementation Method 2
a separating element which is arranged therein in a longitudinally movable manner and which separates two media chambers within the accumulator housing, in particular a chamber with a working gas, such as nitrogen gas, from another chamber with a liquid, such as hydraulic oil

AI summary
The disclosure relates to a hydraulic accumulator comprising an accumulator housing and a separating element which is arranged therein in a longitudinally movable manner and which separates two media chambers within the accumulator housing, in particular a chamber with a working gas, such as nitrogen gas, from another chamber with a liquid, such as hydraulic oil, and a bursting device for reducing an inadmissibly high pressure in the accumulator housing, wherein the bursting device is arranged in the separating element, and when the bursting device bursts, a media-conducting connection between the two media chambers is released via the separating element.
