Regulator Assembly Apertures Engine Lubrication Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current lubrication systems for engines, such as turbochargers, require complex and costly circuitry to actively control lubricant supply parameters like pressure and flow rate, which complicates efficient operation across varying engine speeds.
Innovation Solution
A regulator assembly with a main body, valve element, and spring element is integrated into the fluid line, allowing for adjustable fluid communication through apertures and passages to control lubricant flow based on engine conditions, simplifying the system and reducing complexity and cost.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If complex circuitry and components are used to actively control lubricant supply parameters, then the lubrication system can maintain required supply parameters across varying engine speeds, but the system cost and complexity increase substantially
Solution Approach 1:
The regulator assembly uses the lubricant's own pressure to automatically control the valve element position. The spring element and valve element work together to create a self-regulating system that adjusts flow based on pressure differential without external control signals or complex circuitry.
Solution Approach 2:
The invention uses hydraulic principles where the lubricant pressure acts on the head portion of the valve element to move it between positions. The spring element provides mechanical counterforce, creating a purely mechanical-hydraulic control system that eliminates the need for electrical circuitry.
2Productivity
If a valve element with multiple apertures is used to control lubricant flow, then flow rate can be precisely regulated, but the device complexity increases
Solution Approach 1:
The valve element provides multiple flow control states by switching between different aperture configurations (fully open with all apertures, partially open with some apertures blocked, fully closed). This allows precise flow rate regulation using a single component with fixed geometric features rather than complex adjustable mechanisms.
3Quantity of substance
If direct fluid communication is maintained between passages, then lubricant flow rate is high, but pressure control becomes difficult
Solution Approach 1:
The system dynamically switches between different flow states by moving the valve element between positions. The valve element can be in a first position allowing full flow, a second position blocking some apertures for partial flow, or a third position blocking all apertures for closed state, enabling adaptive control of both flow rate and pressure.
