Power Steering Tank Baffle Rib Flow Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional power steering tank baffles experience fluid volatility and air ingestion due to high flow rates, leading to system noise and fill level accuracy issues, especially when the fluid is cold and at a low level.
Innovation Solution
A power steering tank baffle design comprising a filter member, a hood member, and a rib member, with the filter member having distinct openings and a rib member that directs fluid flow to prevent vertical exit and promote lateral dispersion, reducing fluid velocity and preventing air entry.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional baffles with round holes are used, then fluid can pass through the baffle, but fluid volatility occurs and air can be sucked into the system at high flow rates
Solution Approach 1:
The baffle is segmented into multiple functional zones: an inflow portion with first plurality of openings, an outflow portion with second plurality of openings, and a rib member that divides the openings. This segmentation allows different regions to handle different aspects of fluid flow, preventing volatility while maintaining high flow rates
Solution Approach 2:
Different portions of the baffle have different properties: the inflow portion has larger openings to handle high flow rates, the outflow portion has smaller openings to reduce volatility, and the rib member creates asymmetric flow paths. Each local region is optimized for its specific function to resolve the contradiction between flow rate and reliability
2Productivity
If fluid enters the tank at high flow rate, then productivity is improved, but geyser formation occurs causing air ingestion and system noise
Solution Approach 1:
The rib member acts as an intermediary element between the inflow and outflow portions. It directs and controls the fluid flow through the openings, preventing direct high-velocity entry that causes geyser formation while still allowing high flow rates to pass through the baffle
Solution Approach 2:
Instead of allowing fluid to flow directly upward through a single large opening, the design inverts the approach by using multiple smaller openings with a rib member that redirects flow laterally. This reverses the conventional direct-path approach and eliminates geyser formation while maintaining productivity
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 baffle design effectively reduces fluid volatility, minimizes air ingestion, and maintains laminar flow, enhancing cold start performance and reducing system noise, even at low fluid levels and high flow rates.
Implementation Method 1
The rib member being configured to direct a first portion of a fluid passing through the first plurality of openings in a first direction and a second portion of the fluid passing through the second plurality of openings in a second direction, the first direction being opposite the second direction
Implementation Method 2
maintains laminar flow, enhancing cold start performance and reducing system noise

AI summary
A power steering tank baffle includes a filter member, a hood member and a rib member. The filter member includes an inflow portion and an outflow portion, the inflow portion including a first plurality of openings and a second plurality of openings. The hood member is disposed over the inflow portion. The rib member connects the filter member and the hood member, the rib member being disposed on the inflow portion so as to separate the first plurality of openings and the second plurality of openings.
