Valve Stopper Prevents Vibration Leakage in Work Machine Pressure Chamber
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing driving machine experiences gas leakage from the pressure chamber due to vibration during operation, which requires periodic maintenance to prevent leakage, reducing the machine's workability.
Innovation Solution
The driving machine incorporates a pressure storage container with a communication passageway and a valve mechanism, including a switching inhibition mechanism such as a valve stopper, to maintain the valve in an inactive state and prevent gas leakage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the valve is made movable to allow gas replenishment, then the functionality of the pressure storage container is improved, but the valve becomes susceptible to vibration-induced movement and gas leakage
Solution Approach 1:
A vibration absorbing member is introduced as an intermediary element between the valve and the pressure storage container. This mediator absorbs vibration energy, preventing direct transmission to the valve and its sealing components, thereby maintaining seal integrity while preserving valve functionality.
Solution Approach 2:
The vibration absorbing member is installed in advance to cushion against future vibration impacts. By providing preemptive vibration absorption, the system prevents vibration-induced valve movement and sealing failures before they can occur.
2Reliability
If periodic maintenance is performed to prevent gas leakage, then the reliability is improved, but the workability and productivity of the driving machine are reduced
Solution Approach 1:
The vibration absorbing member enables the system to self-protect against vibration-induced leakage without requiring external maintenance intervention. The automatic vibration absorption function eliminates the need for periodic valve maintenance, allowing the driving machine to maintain gas tightness continuously during operation.
3Reliability
If the valve is securely fixed to prevent movement, then the seal integrity is improved, but the ease of operation for gas replenishment is reduced
Solution Approach 1:
The vibration absorbing member acts as a flexible intermediary that allows the valve to remain securely positioned while accommodating operational movements. The vibration absorption capability provides a buffer that maintains stability during normal operation while allowing controlled access when gas replenishment is needed.
Applied Scientific Principles

Function Achieved in This Case
The implementation of the switching inhibition mechanism effectively inhibits the valve from switching to a communication state due to vibration and air pressure, thereby reducing the need for frequent maintenance and improving the machine's workability.
Implementation Method 1
a striker that strikes a fastener by moving due to a pressure of the gas in the pressure chamber
Implementation Method 2
a vibration absorbing member provided between the communication passageway and the attachment member to absorb vibration received by the valve

AI summary
The present invention improves workability. In a driving machine, a valve mechanism is provided at a top wall of a pressure storage container. The valve mechanism has a valve for replenishing air in a pressure chamber. The valve is inserted from an upper side into a communication passageway formed in the pressure storage container and is attached to a valve attaching portion of the communication passageway. The valve mechanism has a valve stopper, and the valve stopper is disposed at the upper side of the valve and presses a valve core downward. In other words, the valve stopper regulates upward movement of the valve core (valve). Therefore, the attachment state of the valve can be favorably maintained, and the workability of the driving machine can be improved.
