Integrated Check Valve Assembly for Clean Brake Hydraulic Sealing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The conventional check valve assembly process is complex, leading to increased manufacturing costs and a risk of grit and dust entering the assembly, which affects the integrity and performance of the brake system.
Innovation Solution
A combined check valve design where the cap, plug, and spring are integrated with a retainer, forming a single unit that simplifies assembly and reduces the risk of contamination, while ensuring proper seating and sealing performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the cap, plug, and spring are assembled separately into the base body, then the check valve can be constructed with individual replaceable parts, but the manufacturing cost increases and grit and dust may enter the assembly during the assembly steps
Solution Approach 1:
The patent combines the cap, plug, and spring into a single integrated check valve assembly that is pre-assembled as one unit. This merging eliminates the need for separate assembly steps in the base body, reducing manufacturing cost and preventing grit and dust from entering during assembly. The integrated design maintains functionality while simplifying the overall assembly process.
2Ease of manufacture
If the cap, plug, and spring are assembled separately into the base body, then each component can be manufactured independently, but the assembly process becomes complex and time-consuming
Solution Approach 1:
The check valve components (cap, plug, and spring) are pre-assembled into a complete functional unit before being installed into the base body. This preliminary assembly action reduces the complexity of the final installation process, as the entire check valve assembly is installed as one piece rather than requiring multiple separate assembly steps for each component.
3Reliability
If the cap, plug, and spring are assembled separately into the base body, then the components can be quality-tested individually, but the risk of grit and dust entering the assembly increases
Solution Approach 1:
The cap, plug, and spring are combined into a single integrated assembly that can be quality-tested as one unit. This merging reduces the number of assembly steps required in the base body, thereby minimizing the opportunities for grit and dust to enter the assembly. The integrated design maintains reliability through comprehensive quality testing while eliminating contamination risks associated with multiple separate assembly operations.

Function Achieved in This Case
This integrated design reduces manufacturing costs, minimizes the entry of grit and dust, enhances assembly reliability, and improves the sealing and operational performance of the check valve.
Implementation Method 1
A spring is interposed between the cap and the plug to bias the plug toward the seat surface

AI summary
A check valve is arranged in a flow path through which hydraulic fluid flows. The check valve includes: a cap fixed in the flow path; a plug seated on a seat surface provided in the flow path; a first extension provided in the cap and extending from the cap toward the plug; a second extension provided in the plug, extending from the plug toward the cap, and guided by the first extension; and a spring interposed between the cap and the plug to bias the plug toward the seat surface. The check valve further includes a retainer attached to the cap, extending from the cap toward the plug, and locked to the second extension.
