Firearm Gas Redirection Assembly Using Jet Nozzle
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing firearm gas redirection systems require massive and bulky gas chambers and gas pistons to manage recoil, which are inefficient and cumbersome.
Innovation Solution
A firearm gas redirection assembly that directs discharged gases from the barrel towards a jet nozzle edge, using the energy to force the bolt frame rearwardly, eliminating the need for a massive gas chamber and gas piston by integrating a jet nozzle with the bolt frame and forming a gas space that communicates with the bolt, allowing high-velocity gases to displace the bolt frame.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a massive gas chamber and gas piston are used to manage recoil, then recoil management is effective, but the firearm becomes bulky and complex
Solution Approach 1:
The patent extracts the gas management function from a separate bulky gas chamber and piston system, and integrates it directly into the barrel structure through gas vents and the jet nozzle assembly. This extraction eliminates the need for dedicated gas storage components while maintaining recoil management effectiveness.
Solution Approach 2:
The patent merges the gas redirection function with the existing barrel and jet nozzle structures. The gas vents are formed in the barrel, and the jet nozzle is positioned to receive gases directly from the barrel, combining multiple functions (barrel, gas redirection, recoil management) into an integrated assembly.
2Reliability
If a massive gas chamber and gas piston are used to manage recoil, then recoil management is effective, but the firearm size increases
Solution Approach 1:
The patent removes the need for a separate gas chamber by extracting the gas management function and embedding it within the barrel structure. The gas vents and jet nozzle assembly occupy minimal space compared to a dedicated gas chamber, significantly reducing the overall firearm volume.
Solution Approach 2:
The jet nozzle is positioned concentrically around the barrel, with the gas flow path nested within the existing barrel-jet nozzle assembly. This nesting arrangement allows gas redirection components to occupy space that would otherwise be empty or require additional external structures.
3Volume of moving object
If gas redirection is achieved without a gas chamber and piston, then the firearm is more compact, but the mechanism for directing gases must be integrated into existing structures
Solution Approach 1:
The patent combines the gas redirection function with the barrel and jet nozzle structures. The gas vents are formed directly in the barrel, and the jet nozzle is positioned to receive gases directly from the barrel, merging gas redirection with existing components rather than adding separate mechanisms.
Solution Approach 2:
The jet nozzle serves multiple functions: it directs the projectile path, manages gas flow, and contributes to recoil management. This multi-functionality eliminates the need for dedicated gas redirection components, simplifying the overall structure while maintaining compactness.
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
This solution enables efficient bolt frame and bolt action without the need for a massive gas chamber or gas piston, providing a more compact and efficient mechanism for recoil management in firearms.
Implementation Method 1
discharge of the firearm forces a high velocity gas through from the at least one gas vent against the jet nozzle edge through the gas space, so as to displace the bolt frame rearwardly
Implementation Method 2
use the energy from the discharged powder gases to force the bolt frame rearwardly

AI summary
A firearm gas redirection assembly directionally directs discharged gases from a barrel towards a bolt frame, and uses the energy from discharged gases to force a bolt rearwardly in an action. The barrel has an elongated body, an inner barrel sidewall, an outer barrel sidewall, a rear end, and a forward end. The forward end of barrel forms gas vents. The barrel is fixed motionless on the frame of the weapon. A jet nozzle concentrically couples around the barrel and integrates with a bolt frame. The jet nozzle has inner and outer jet sidewalls and a jet nozzle edge. The inner jet sidewall and outer barrel sidewall form a gas space that is in communication with the bolt frame. Discharge of firearm forces high velocity gas through gas vents that form in the barrel, through gas space, and finally against the jet nozzle edge. This forces bolt frame rearwardly.
