Electromagnetic Fluid Valve Flow Guide Bolt
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electromagnetic fluid valves experience turbulent flow conditions due to multiple radial inlet openings, leading to fluctuating flow forces that destabilize the fluid flow, making it difficult to maintain a laminar flow.
Innovation Solution
A bolt with a special outer contour, such as conical, pyramid-shaped, or hyperboloid-shaped, is inserted into the flow channel to deflect the pressure medium towards the outlet opening, ensuring a targeted and stable flow path.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If multiple radial inlet openings are provided in the housing, then the pressure medium can be supplied to the valve, but turbulent flow occurs leading to fluctuating flow forces
Solution Approach 1:
A flow guide element is introduced as an intermediary component between the radial inlet openings and the valve slide. This flow guide element redirects the pressure medium from the radially inward flow direction to a direction parallel to the valve slide, preventing direct collision of fluid streams and eliminating turbulence while maintaining effective pressure medium supply to the valve.
2Adaptability or versatility
If a movable slide is used to regulate flow, then the valve can control pressure medium flow, but fluctuating flow forces arise due to turbulence
Solution Approach 1:
The flow guide element serves as a mediator that separates the pressure medium supply function from the flow regulation function. By redirecting the pressure medium before it reaches the valve slide, the flow guide element eliminates turbulent flow forces that would otherwise act on the movable slide, allowing stable flow regulation without fluctuating forces.
3Quantity of substance
If the pressure medium flows towards each other inside the housing, then the inlet openings can be utilized, but turbulence is generated
Solution Approach 1:
The flow guide element acts as an intermediary structure that intercepts the pressure medium from multiple radial inlet openings and redirects it in a coordinated manner. This prevents the harmful effect of fluid streams colliding and generating turbulence, while still utilizing all inlet openings for pressure medium supply.
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
This configuration prevents turbulence and ensures a laminar flow within the valve, reducing fluctuating flow forces and stabilizing the fluid flow, thereby improving the operational efficiency of the valve.
Implementation Method 1
the valve slide (30) is moved in a manner known per se via an electromagnet by energizing the coil (14)
Implementation Method 2
the outer contour of the bolt (50) is designed in the area of the openings (12, 22) in such a way that the pressure medium is selectively deflected from the inlets (12, 22) to the outlet (A)

AI summary
The valve has housing portions (10, 20) comprising inlet apertures (12, 22) that are arranged opposite to each other. An outflow hole (A) is located between the inlet apertures by an axial movable slider (30) i.e. inner slider, for flow control of a print medium. A bolt (50) is provided for a flow guide with an outer contour i.e. twin cone or univalve Hyperboloids, so that a print medium is flowed from the inlet apertures that strike the outer contour of the bolt. The print medium is turned back toward the outflow hole.
