Compressed Air Processing System Regeneration Sequence Valve Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing compressed air processing systems for commercial vehicles face inefficiencies in regenerating compressed air, leading to decreased regeneration efficiency due to high-pressure air remaining in the supply line and potential valve damage from sudden pressure changes, along with increased manufacturing costs from complex control logic and potential losses during regeneration.
Innovation Solution
A compressed air processing system that employs a regeneration sequence valve and an unloader valve, where the unloader valve is opened before the regeneration line, delaying the opening of the regeneration line until a preset pressure is reached, and allowing for controlled valve switching to minimize pressure shocks and optimize regeneration efficiency without additional control logic or parts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If regeneration is performed immediately without delaying the regeneration line opening, then regeneration process starts quickly, but high-pressure air remains in the supply line causing decreased regeneration efficiency
Solution Approach 1:
The unloader valve is opened before the regeneration line to preliminarily discharge high-pressure air from the supply line. This preliminary action removes the harmful high-pressure air that would otherwise decrease regeneration efficiency, allowing the drying agent to effectively remove moisture without competition from compressed air pressure.
Solution Approach 2:
The unloader valve acts as an intermediary component between the supply line and the regeneration line. It mediates the pressure transition by first discharging high-pressure air before allowing the regeneration line to open, thus protecting the regeneration process from the adverse effects of high-pressure air while maintaining system connectivity.
2Reliability
If the regeneration line opens immediately with high-pressure air, then air supply is maintained, but sudden pressure changes cause valve damage and reduced durability
Solution Approach 1:
The unloader valve opens in advance to preliminarily discharge high-pressure air before the regeneration line opens. This preliminary pressure relief action prevents sudden pressure changes that would damage valves, thereby improving valve durability without requiring complex control sequences.
Solution Approach 2:
The unloader valve provides beforehand cushioning by discharging high-pressure air before the regeneration process begins. This cushioning effect protects the regeneration line and associated valves from sudden pressure shocks, extending their service life while maintaining simple control logic.
3Productivity
If additional control logic and parts are added to optimize regeneration timing, then regeneration efficiency improves, but manufacturing costs increase
Solution Approach 1:
The unloader valve automatically performs the function of discharging high-pressure air before regeneration based on its inherent pressure-responsive operation. This self-service mechanism eliminates the need for additional control logic or parts, achieving improved regeneration efficiency while keeping manufacturing costs low.
Solution Approach 2:
The unloader valve serves multiple functions: it acts as both a pressure relief device and a regeneration timing control mechanism. By making this existing component multi-functional, the system achieves optimized regeneration efficiency without adding extra parts or increasing manufacturing complexity.

Function Achieved in This Case
This approach enhances regeneration efficiency by ensuring sufficient removal of high-pressure air, improves valve durability, simplifies control logic, reduces manufacturing costs, and minimizes air loss during regeneration, while effectively discharging foreign substances through the sep-cooler.
Implementation Method 1
a regeneration sequence valve configured to open a regeneration line by receiving control inputs through a first electronic control valve and a second electronic control valve, in which the regeneration sequence valve is configured to open the regeneration line late by a delay until reaching a preset pressure
Implementation Method 2
since the system is implemented such that the unloader valve is opened before the regeneration line is opened, there is an effect that it is possible to prevent overpressure from being generated in the compressed air supply line
Implementation Method 3
a drier unit including a filter cartridge filled with a drying agent is included in a compressed air processing system. Such a dryer unit is installed on a supply line of compressed air to discharge dry and clean air by not only filtering out oil, but removing water contained in compressed air
Implementation Method 4
Compressed air at high pressure is required to drive such pneumatic systems. Such compressed air is produced through a compressor, which is driven by an engine or a driving motor

AI summary
The present disclosure provides a compressed air processing system of which the operation of supplying compressed air and the regeneration operation can be efficiently controlled by an electronic control unit. In particular, the present disclosure is characterized in that the pressure of a regeneration sequence valve installed in a regeneration line is increased over a set pressure by controlling a valve, which is electronically controlled, to switch, so the opening time of the regeneration line is delayed in comparison to the opening time of an unloader valve, whereby regeneration efficiency is improved.
