Diaphragm Pump Valve Assembly With Angled Inlet Channel Layout
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing diaphragm pumps have a sequential construction that requires an inlet chamber and an outlet chamber to be arranged in front of the valve assembly, leading to increased pump length and limited design flexibility for the inlet arrangement.
Innovation Solution
The valve assembly features an inlet channel with a first part extending at an angle to a second part, allowing the inlet chamber to protrude closer to the pumping chamber and potentially integrating into the valve plate, thereby enhancing design flexibility and reducing pump length.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the inlet chamber and outlet chamber are arranged in front of the valve assembly in a sequential construction, then the pump structure is simple and easy to manufacture, but the pump length increases and design flexibility is limited
Solution Approach 1:
The patent transforms the sequential linear arrangement of inlet chamber-valve assembly-outlet chamber into a multi-dimensional integrated structure where the inlet chamber protrudes into the valve plate from the pumping chamber side, utilizing three-dimensional space more efficiently to reduce the overall pump length while maintaining manufacturing feasibility
Solution Approach 2:
The patent merges the inlet chamber with the valve plate by allowing the inlet chamber to protrude into the valve plate structure, integrating two previously separate components into a unified assembly that reduces total length while preserving ease of manufacture
2Ease of operation
If the inlet chamber is arranged in front of the valve assembly, then the fluid flow path is straightforward, but the design flexibility for inlet arrangement is limited
Solution Approach 1:
The patent enables the inlet chamber to be positioned in multiple possible locations by allowing it to protrude into the valve plate from the pumping chamber side, providing design flexibility in arranging the inlet chamber at different positions and orientations while maintaining straightforward fluid flow management
3Length of moving object
If the inlet channel is designed with a first part extending at an angle to a second part, then the inlet chamber can protrude closer to the pumping chamber, but the channel geometry becomes more complex
Solution Approach 1:
The patent divides the inlet channel into a first part and a second part with different orientations, where the first part extends at an angle and the second part connects to the pumping chamber, allowing the inlet chamber to protrude closer while managing geometric complexity through segmented design

AI summary
The invention relates to a valve assembly for a diaphragm pump, the valve assembly having an inlet side and an outlet side. A first outlet channel (23) leads from an inlet opening (24) arranged on the inlet side to an outlet opening (25) arranged on the outlet side, and a second outlet channel (26) leads from an inlet opening (27) arranged on the inlet side to an outlet opening (28) arranged on the outlet side. An inlet channel (30) has a first part (31) and a second part (32), the second part (32) having an outlet opening (33), which is arranged on the inlet side, and the first part (31) extending at an angle to the second part (32). An inlet valve body (40) is provided at the outlet opening (33) of the second part (32) of the inlet channel (30), and a first outlet valve body (41) is provided at the outlet opening (25) of the first outlet channel (23). The outlet opening (28) of the second outlet channel (26) is closed and opened either by a second outlet valve body or also by the first outlet valve body (41).
