Coaxial Valve Assembly for Compact One-Way Displacement Pumps
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Many fluid pumps have complex component arrangements that make them difficult to adapt to confined spaces and do not efficiently extract fluid from containers, as they often require specific actuator and outlet relationships and separate one-way inlet and outlet valves.
Innovation Solution
A simplified valve assembly with a coaxially received valve member within a tubular casing, featuring resilient inlet and outlet discs that allow for controlled one-way fluid flow, integrated into a displacement pump to create a variable volume compartment that alternately draws and discharges fluid, facilitating easier adaptation and efficient fluid extraction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate one-way inlet and outlet valves are used, then reliable fluid flow control is achieved, but device complexity increases
Solution Approach 1:
The patent combines separate inlet and outlet valves into a single integrated valve assembly. The valve member includes both an inlet valve portion and an outlet valve portion that work together within one housing, eliminating the need for separate valve components while maintaining reliable one-way fluid flow control in both directions.
2Reliability
If specific actuator and outlet relationships are required, then pump function is achieved, but adaptability to confined spaces is reduced
Solution Approach 1:
The valve assembly is designed with a compact, self-contained structure that can be integrated into various pump configurations without requiring specific actuator-outlet relationships. The integrated design allows the same valve assembly to function reliably in different spatial arrangements and confined space applications.
3Ease of manufacture
If pump components are simplified, then ease of manufacture and adaptation is improved, but fluid flow control reliability may be compromised
Solution Approach 1:
By merging inlet and outlet valves into a single integrated assembly with common housing and coordinated valve members, the design simplifies manufacturing while maintaining reliable fluid flow control. The integrated structure reduces the number of separate components that need to be manufactured and assembled, yet preserves the functional integrity of both valve operations.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution enables a more compact and efficient fluid dispensing mechanism that can be easily adapted to various spaces and effectively draws and discharges fluid from containers, improving fluid extraction efficiency.
Implementation Method 1
The inlet disc is resiliently deflectable to be deflected from engaging the wall to permit fluid flow axially therepast in a direction from the inlet end towards the outlet end. The outlet disc is resiliently deflectable to be deflected from engaging the wall to permit fluid flow axially therepast in a direction from the inlet end towards the outlet end.

AI summary
A valve assembly with a valve member coaxially received within a valve casing and interacts with the casing to provide a one-way inlet valve at one end of the valve casing and a one-way outlet valve at the other end of the casing with an annular compartment therebetween adapted to be coupled to a variable volume compartment and thereby together provide a simplified construction for valving components of a fluid pump.
