Hydraulic Pressure Amplifier Connecting Plug Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hydraulic pressure amplifiers are heavy and require significant structural space due to the need for capsules or cover plates to manage the diameter expansion for assembly and sealing of high-pressure fittings.
Innovation Solution
The outlet duct extends through a connecting plug on the high-pressure side, eliminating the need for capsules or intermediate pieces, allowing independent shaping of the assembly opening and duct, and incorporating a closing plug to simplify assembly and reduce weight by using a shorter connecting plug with a pressure sensor adapter.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a capsule or cover plate is used to seal and provide transition between the outlet valve bore and outlet duct, then reliable sealing and connection are achieved, but the device becomes heavier and requires more structural space
Solution Approach 1:
The patent merges the functions of the capsule/cover plate with the housing structure itself. The housing is designed with an integrated sealing surface and structural features that directly provide the transition and sealing functions previously requiring separate capsule or cover plate components. This integration eliminates the need for additional sealing components while maintaining reliable sealing between the outlet valve bore and outlet duct.
Solution Approach 2:
The housing structure is designed to perform multiple functions simultaneously: it provides structural support, creates the sealing interface, and forms the transition geometry between the outlet valve bore and outlet duct. This multi-functionality eliminates the need for separate specialized components like capsules or cover plates, reducing overall device weight and complexity while maintaining sealing reliability.
2Ease of manufacture
If a capsule is used to reverse diameter expansion for assembling the outlet valve, then proper connection geometry is achieved, but the device becomes larger and heavier
Solution Approach 1:
The patent combines the diameter transition function with the housing structure. The housing is designed with integrated geometric features that directly provide the necessary diameter expansion and connection geometry for the outlet valve, eliminating the need for a separate capsule component. This integration maintains ease of manufacture while reducing device volume.
Solution Approach 2:
The patent utilizes the radial dimension of the housing structure to provide the diameter expansion needed for outlet valve assembly. Instead of extending axially with a separate capsule, the housing incorporates stepped or conical surfaces in the radial direction that create the necessary geometry transition, allowing proper outlet valve assembly without increasing axial length.
3Ease of manufacture
If the upper part is extended to accommodate the outlet duct and fitting geometry, then proper connection is achieved, but the device becomes larger
Solution Approach 1:
The patent applies local quality by providing the extended connection geometry only where needed in the housing structure, rather than uniformly extending the entire upper part. The housing incorporates localized geometric features such as stepped surfaces, conical sections, or integrated fitting mounts at specific locations to accommodate the outlet duct and fitting connection, maintaining compact overall dimensions while ensuring proper connection geometry where required.

AI summary
A hydraulic pressure amplifier with a housing which has an end face at a low pressure side and an end face at a high pressure side and a circumferential wall between the two end faces, wherein an outlet valve is arranged adjacent the end face on the high pressure side, and an outlet duct for the hydraulic liquid which is under high pressure. In a pressure amplifier of the above-described type, the outlet duct opens into the circumferential wall or extends through a connection plug which is screwed into the end face on the high pressure side and closes off an assembly duct which receives the outlet valve.
