Three-Stage Pressure Booster With Fluid Return Pressure Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional pressure boosters have complex structures due to the need for balancing pressure values between chambers, leading to inefficient energy use and increased fluid consumption, as they require mechanisms like compression springs and grooves to facilitate piston movement.
Innovation Solution
A pressure booster with a three-stage cylinder structure, where pistons are displaced without balancing pressure values, utilizing a fluid supplying mechanism and discharge return mechanisms to alternately supply and discharge fluid between pressurizing chambers, allowing for efficient pressure boosting up to three times the original pressure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If pressure balancing mechanisms (compression springs, grooves) are integrated into the pressure booster to enable piston movement, then the pressure boosting function is achieved, but the device structure becomes complicated
Solution Approach 1:
The patent extracts and removes the complex pressure balancing mechanisms (compression springs, grooves) from the pressure booster structure. Instead of integrating these mechanisms within the booster, the invention uses a external pressure control system that regulates pressure through fluid supply and discharge, thereby achieving pressure boosting without internal mechanical complexity
Solution Approach 2:
The patent applies pneumatic principles by using fluid pressure control to drive piston movement. Instead of mechanical spring-based balancing, the system uses controlled fluid supply to pressurizing chambers and discharge return mechanisms to create pressure differences, enabling piston displacement through pneumatic forces rather than mechanical balancing structures
2Reliability
If pressure balancing mechanisms are used to facilitate piston movement, then the pressure boosting function is achieved, but energy consumption increases
Solution Approach 1:
The patent implements continuous useful action through the discharge return mechanism that recycles discharged fluid back to the fluid supply source. This creates a closed-loop system where fluid is continuously circulated and reused, eliminating the need for continuous external fluid supply and reducing energy consumption associated with fluid replenishment and pressure maintenance
Solution Approach 2:
The system achieves self-service through the discharge return mechanism that automatically returns discharged fluid to the supply source without external intervention. The pressure control system self-regulates by controlling fluid supply and discharge, eliminating the need for external energy-intensive pressure balancing mechanisms
3Reliability
If pressure balancing mechanisms (compression springs, grooves) are integrated into the pressure booster, then piston movement is enabled, but fluid consumption increases
Solution Approach 1:
The patent applies the discarding and recovering principle through the discharge return mechanism that captures and returns discharged fluid to the fluid supply source. Instead of discarding used fluid, the system recycles it back into the system, significantly reducing fluid consumption and eliminating waste associated with traditional pressure balancing approaches

AI summary
When a fluid is supplied to a first pressure-boosting chamber (32a) and/or a second pressure-boosting chamber (32b) of a pressure booster (10, 10A, 10B), either a first electromagnetic valve unit (22) supplies a fluid discharged from a first pressurizing chamber (34a) to a second pressurizing chamber (34b), or a second electromagnetic valve unit(26) supplies a fluid discharged from a third pressurizing chamber (36a) to a fourth pressurizing chamber (36b).
