Firearm Suppressor Valve Action for Gas Flow Metering
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current suppressor systems are inadequate in effectively controlling the flow of gas produced by firearm discharge, leading to excessive noise and recoil, as they fail to provide sufficient metering of the gas flow.
Innovation Solution
A suppressor system comprising a core with a radially dispersed hole configuration, a main can with a baffle structure, and a spring that axially biases the main can relative to the core, facilitating a valve action to control the gas flow by altering pathways for the gas to escape, thereby reducing noise and recoil.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If the volume of gas is allowed to exit the barrel at high speed, then the propulsion force is maximized, but the noise and recoil increase significantly
Solution Approach 1:
The suppressor divides the gas flow control into multiple stages through segmented baffle structures and multiple apertures arranged in concentric circles. The first baffle with first apertures and the second baffle with second apertures create sequential flow restriction zones, progressively reducing gas velocity while maintaining propulsion efficiency.
Solution Approach 2:
The suppressor introduces intermediary baffle structures between the barrel and the external environment. These baffles act as mediators that intercept and redirect the high-velocity gas flow, forcing it to pass through controlled apertures rather than exiting directly, thereby reducing noise and recoil while preserving propulsion.
2Object-generated harmful factors
If conventional suppressors are used to control gas flow, then some noise reduction is achieved, but the gas flow metering is insufficient
Solution Approach 1:
The suppressor employs local quality variations through apertures of different sizes arranged in concentric circles on multiple baffles. The aperture dimensions and spacing are precisely controlled to create specific flow restriction zones, enabling precise metering of gas flow at different stages of expansion.
Solution Approach 2:
The suppressor transitions from simple axial flow control to multi-dimensional flow management by arranging apertures in concentric circular patterns on multiple baffles at different axial positions. This creates three-dimensional flow paths that provide precise control over gas expansion and velocity profiles.

Function Achieved in This Case
The suppressor system effectively dampens the sound and reduces recoil by metering the gas flow, improving the overall performance of the firearm by controlling the speed of gas escape and utilizing adjustable components for customizable performance.
Implementation Method 1
a spring configured to axially bias the main can with respect to the core
Implementation Method 2
The suppressor may be configured to control a flow of a volume of gas, produced by the discharge of the firearm

AI summary
Suppressor systems and apparatuses for use with firearms are provided. A suppressor includes a core, a main can, and a spring. The core defines a first channel that intersects a radially dispersed hole configuration and is configured to be coupled to a firearm. The main can is disposed around the core and includes a baffle structure. The baffle structure includes a plurality of baffles that define a second channel and a plurality of chambers intersecting the second channel. In various configurations, the core and/or the main are either a unitary piece or each formed from a plurality of components. The spring is configured to axially bias the main can with respect to the core, thereby providing for a valve action that controls a flow of a volume of gas produced by a discharge of the firearm.
