Solution Overview
Problem
Existing hydraulic support elements for valve drives in internal combustion engines are complex and costly to manufacture due to intricate designs and tight tolerances, making them difficult and expensive to produce.
Innovation Solution
A simplified hydraulic support element design featuring a detachable bottom closure and a piston with a groove for the retaining element, allowing for easier assembly and production, along with a 'chimney' design that increases medium reserve volume and includes a ball valve for fluid regulation between pressure chambers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the piston is designed with integrated bottom closure and complex internal structures, then the sealing and structural integrity are improved, but the manufacturing complexity and cost increase significantly
Solution Approach 1:
The piston is divided into multiple separate components: the piston body, bottom closure, and retaining element. These segments are manufactured separately and then assembled together, which simplifies the manufacturing process for each individual component while maintaining the overall sealing integrity through the seal element that connects them.
2Reliability
If tight tolerances and intricate designs are used in the hydraulic support element, then the functional performance is improved, but the manufacturing cost and difficulty increase
Solution Approach 1:
By segmenting the piston into separate manufacturable components with less stringent tolerance requirements, the overall manufacturing difficulty is reduced. Each component can be manufactured using simpler processes, and the assembly maintains functional performance through proper sealing and fitting.
Solution Approach 2:
The retaining element acts as an intermediary component that connects the bottom closure to the piston body. This mediator allows for easier assembly and disassembly while maintaining the structural integrity and functional performance of the overall piston assembly.
3Ease of manufacture
If the bottom closure is made detachable from the piston, then the ease of assembly and production is improved, but the potential for leakage or connection failure increases
Solution Approach 1:
The retaining element serves as a reliable intermediary connection between the bottom closure and piston body. This dedicated connecting component provides a secure attachment that prevents leakage and connection failure while still allowing for detachable assembly and disassembly during manufacturing or maintenance.
Solution Approach 2:
The groove design in the piston body provides a precise geometric copy or template for the retaining element, ensuring proper positioning and alignment. This geometric replication ensures consistent and reliable connections during assembly while maintaining ease of manufacturing.

AI summary
A hydraulic support element including a housing with a central bore and a bottom face that is provided on one axial end of the housing, a piston that is arranged in the bore of the housing, the piston is connected to a bottom closure so as to define a first pressure chamber and a second pressure chamber is defined between the bottom face and the bottom closure. A valve is provided between the first pressure chamber and the second pressure chamber to regulate a fluid connection between the pressure chambers, and a seal formed between the piston and the bottom closure with the bottom closure being affixed to the piston in a detachable manner.
