Bidirectional Valve Retaining Body for Faster Pump Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing automatic bidirectional valves for high-pressure pumps require complex design and assembly due to the need for machined shoulders to maintain elastic elements in position, leading to increased design, production, and assembly times, as well as costs.
Innovation Solution
A valve design featuring a retaining body fixed to the valve body to hold elastic elements in place, eliminating the need for machined shoulders and allowing for quick assembly and maintenance, with the option for the retaining body to be removably fixed via a snap coupling mechanism, and a monolithic valve body made from durable materials like stainless steel, brass alloys, or aluminum for enhanced resistance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If machined shoulders are made in the pump head to maintain elastic elements in position, then the valve can function properly, but the design complexity and manufacturing complexity increase
Solution Approach 1:
The invention introduces a retaining body as a separate component that houses the elastic elements and attaches to the valve body. This segments the valve into modular components (valve body, retaining body, elastic elements) rather than requiring integrated machined shoulders in the pump head, thereby reducing the complexity of the pump head design while maintaining proper valve function.
2Reliability
If machined shoulders are made in the pump head to maintain elastic elements, then the valve assembly is complete, but the production time and assembly time increase
Solution Approach 1:
The elastic elements are pre-installed within the retaining body during valve manufacturing, rather than requiring installation in the pump head during final assembly. This preliminary action of pre-assembling the elastic elements in the retaining body reduces the time and complexity of the final pump assembly process.
3Reliability
If complex machined shoulders are required in the pump head, then the elastic elements can be maintained in position, but the costs increase
Solution Approach 1:
The invention extracts the elastic element positioning function from the pump head structure and relocates it to a dedicated retaining body. This separates the positioning function into a specialized component that can be manufactured more economically than custom-machined shoulders in the pump head, thereby reducing overall manufacturing costs while maintaining proper elastic element positioning.

Function Achieved in This Case
This solution simplifies the assembly and maintenance of the valve, reduces design and production times, and enhances the durability and resistance of the valve, allowing for faster operation and reduced fatigue in pump heads, while using lighter and more machinable materials like aluminum.
Implementation Method 1

AI summary
An automatic bidirectional valve includes: a valve body, a central conduit that crosses the valve body and is provided with a first opening in a first end of the valve body and a second opening made in an opposite second end thereof, and a peripheral conduit made in the valve body, provided with a first opening, made in a portion of the valve body between the first and second ends, and a second opening made in the second end. A first shutter is movable between a closing position and an opening position, a first elastic element configured to generate a force adapted to maintain the first shutter in the closing position, a second shutter movable between a closing position, and an opening position, a second elastic element configured to generate a force to maintain the second shutter in the closing position, and a retaining body fixed to the valve body.
