Filling Connection With Automatic Screw-Actuated Venting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing filling connections for compressed air or gas bottles require separate manual operation of pressure relief devices, which can lead to accidents due to forgotten operation during screwing in and out.
Innovation Solution
Integration of an internal automatic venting device that activates when the screw ring is operated, relieving pressure during screwing-in and screwing-out movements, eliminating the need for separate manual operation of pressure relief devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate manual pressure relief devices are provided on the filling connection, then pressure can be relieved, but the operation can be forgotten leading to accidents
Solution Approach 1:
The patent combines the pressure relief function with the screw ring actuation mechanism. The screw ring serves dual purposes: connecting the filling connection to the cylinder and automatically actuating the pressure relief device through its rotational movement. This merging eliminates separate manual pressure relief operations while maintaining safety.
Solution Approach 2:
The pressure relief device is designed to activate automatically during the screwing-in process before the connection is fully tightened. The initial rotation of the screw ring triggers the pressure relief mechanism in advance, ensuring pressure is relieved before any potential overpressure damage can occur, making manual intervention unnecessary.
2Reliability
If separate pressure relief devices are provided on the filling connection, then pressure relief is possible, but additional components increase device complexity
Solution Approach 1:
The pressure relief valve is integrated into the screw ring assembly rather than being a separate component. The screw ring's rotational movement directly actuates the valve mechanism, combining two functions (connection and pressure relief) into a single integrated component, thereby reducing overall device complexity.
Solution Approach 2:
The screw ring is designed with multi-functionality: it serves as both the connecting element for attachment to the cylinder and as the actuating mechanism for the pressure relief device. This universal design eliminates the need for separate dedicated pressure relief components, simplifying the overall device structure.
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
Prevents accidents by ensuring automatic pressure relief during connection and disconnection, reducing the risk of damage and operational errors, as the filling connection vents automatically with the screw ring's movement.
Implementation Method 1
the interior of the filling connection is vented by means of an internal venting device (70, 80) which is actuated automatically when the screw ring (30) is operated by an operator

AI summary
The filling connector has an internal ventilation unit which is actuated with the operation of a screwed ring (30) by an operator in an automatic manner. The filling connector is provided with a check valve at its end. The internal ventilation system has a releasing or venting valve and a bolt. A unit is provided for limiting the swiveling angle.
