Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing multi-way flood valves for technical liquids, such as waxes, lack the ability to provide stepless regulation of flow volume and are limited in their ability to supply multiple outlets in different directions, requiring separate systems for varying preservative needs within vehicle underbody assemblies.
Innovation Solution
A multi-way flood valve design featuring a fixed hollow shaft with a linearly displaceable control piston, supported by guide and sealing rings, and a wax depot under pressure, allowing for stepless regulation of wax flow through overlapping bores with rectangular cross-sections, enabling multiple outlet directions and efficient return of excess wax.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a rotary control valve with overlapping openings is used to supply multiple flood points, then multiple outlets can be supplied simultaneously, but the flow rate regulation is limited and cannot provide stepless regulation
Solution Approach 1:
The invention replaces the static rotary valve mechanism with a dynamic linearly movable control piston that can be positioned continuously along its travel path. This dynamic linear movement allows the control piston to progressively overlap with different wax feed holes, enabling stepless flow rate regulation from minimum to maximum while simultaneously supplying multiple flood points through different outlets.
Solution Approach 2:
The invention transitions from rotary motion in one dimension to linear motion in another dimension. The control piston moves linearly along the longitudinal axis of the hollow shaft, creating overlapping flow paths with wax feed holes at different positions. This dimensional change enables continuous flow regulation while maintaining the capability to supply multiple outlets simultaneously.
2Adaptability or versatility
If separate systems are arranged for each area to achieve varying preservative needs, then flow regulation for different areas is improved, but device complexity increases
Solution Approach 1:
The invention creates a universal multi-functional flood valve where a single control piston can regulate flow to multiple different flood points through different outlets. By moving the control piston to different positions, the system can supply wax to various flood points with different flow rates using one integrated device, eliminating the need for multiple separate systems while maintaining the ability to meet varying preservative needs in different areas.
Solution Approach 2:
The invention segments the flow control function into multiple independently controllable pathways within a single device. The hollow shaft contains multiple wax feed holes and the control piston can selectively overlap with different combinations of these holes, creating segmented flow paths to different outlets. This allows independent regulation of flow to each flood point while using a single unified valve structure.
3Ease of operation
If the control piston is linearly displaced to regulate flow, then stepless regulation is achieved, but the mechanism requires precise guiding and sealing
Solution Approach 1:
The control piston incorporates integrated sealing rings that self-seal against the hollow shaft wall during linear movement. The sealing rings are designed to automatically maintain contact and seal the gaps between the control piston and shaft wall, eliminating the need for external sealing mechanisms. This self-sealing feature reduces manufacturing precision requirements while enabling smooth stepless flow regulation through linear piston displacement.
Solution Approach 2:
The control piston and hollow shaft are designed with homogeneous material properties and matching surface finishes to minimize friction and ensure smooth linear movement. The sealing surfaces are treated uniformly to create consistent sealing contact along the entire travel path of the control piston, reducing variability in guiding and sealing performance while enabling precise stepless flow control.

Function Achieved in This Case
Enables efficient, stepless regulation of wax flow to multiple outlets with consistent pressure, ensuring clean and needs-based supply while returning excess wax to the depot, enhancing technical economy and versatility in cavity preservation systems.
Implementation Method 1
a single depot is responsible for supplying the wax supply. Due to the overpressure, the wax is immediately at the openings of the accesses and is available there and can flow into the desired accesses after opening them

AI summary
The invention relates to a multi-port flooding valve for technical fluids, such as technical waxes, with linear flooding volume control for the optimal supply of the technical fluid to points of demand. For this purpose, a piston (2) that moves in a linear and rotary manner in a fixed hollow shaft (1) is provided with a wax-supply borehole (10). This borehole is provided with the same cross-section in terms of shape and size as the two through-boreholes (6) of the hollow shaft (1) arranged spaced apart from one another. The spacing of the two through-boreholes (6) of the hollow shaft (1) correspond to the possible linear path of the control piston (2). The hollow shaft (1) is provided with a residual wax discharge (7) in the region outside the wax deposit assembly (4). Two wax flooding discharge boreholes (8) arranged opposite one another in an offset manner are arranged on the hollow shaft (1), upstream and downstream of the residual wax discharge (7), which wax flooding discharge boreholes are connected to the wax flooding connecting pieces (9.1 and 9.2) arranged on the outer wall of the hollow shaft (1).
