Pressure Booster Cylinder With Self-Switching Piston Flow Path
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pressure boosters require complex configurations due to the need for a spring-biased switching valve, which increases energy consumption and complicates the system.
Innovation Solution
A pressure booster with a cylinder main body divided into two chambers by a division wall, where a first piston and a second piston are coupled via a rod, and a biasing member biases at least one piston to simplify the configuration by using a communicating member with a communicating hole to switch between expansion and contraction states, allowing fluid to pressurize and be reused.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a spring-biased switching valve is used to switch the channel, then the pressure booster can operate, but the configuration becomes complicated
Solution Approach 1:
The patent removes the spring-biased switching valve from the system entirely. Instead, it uses a solenoid valve for channel switching and relies on the inherent pressure differential and piston mechanics to achieve the pressure boosting function, thereby simplifying the overall configuration while maintaining operational capability
Solution Approach 2:
The piston rod serves multiple functions: it transmits mechanical force between pistons, acts as a structural support element, and works in conjunction with the solenoid valve to control fluid flow paths. This multi-functionality reduces the need for separate dedicated components, simplifying the system configuration
2Ease of operation
If a spring-biased switching valve is used, then channel switching is achieved, but energy consumption increases
Solution Approach 1:
The patent replaces the spring-biased mechanical switching mechanism with an electrically actuated solenoid valve for channel switching. This substitution allows for more efficient energy usage as the solenoid only consumes energy during switching transitions rather than requiring continuous energy input to maintain the switching mechanism in a biased state
Solution Approach 2:
The system uses the fluid pressure itself and the piston motion to automatically control the flow paths and pressure boosting process. The solenoid valve controls channel switching based on operational needs, and the pressure differential naturally drives the pressure boosting function without requiring additional energy input for the switching mechanism

Function Achieved in This Case
This configuration reduces energy consumption by using the fluid to pressurize itself and simplifies the system by eliminating the need for a spring-biased switching valve, achieving efficient pressure boosting with a simpler design.
Implementation Method 1
a biasing member configured to bias at least one of the first piston and the second piston in a direction in which the first piston moves toward the pressure boosting chamber
Implementation Method 2

AI summary
A pressure booster constituting a cylinder apparatus is provided with a first piston and a second piston that are coupled to each other by a rod. A connection member provided to the second piston is configured so as to be displaceable from a connection position to a blocking position as a result of the connection member making contact with a cylinder body when the second piston is displaced in a direction where a boosting chamber contracts, and so as to be displaceable from the blocking position to the connection position as a result of the connection member making contact with the cylinder body when the second piston is displaced in a direction where the boosting chamber expands.
