Gas Piston Spring Plunger Recoil Bouncing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Gas-powered weapons experience energy loss and bouncing of closure parts due to the recoil of gas pistons, which can prevent cartridge ignition, especially in weapons with limited installation space.
Innovation Solution
Integration of a spring and plunger within the gas piston, where the plunger is supported in the weapon housing, allowing the gas piston to be reset by gas pressure and then returned to its starting position by the compressed spring, preventing bouncing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the gas piston recoils after the working stroke, then the gas piston can be reset for the next cycle, but the closure parts bounce and energy is lost preventing cartridge ignition
Solution Approach 1:
A buffer element is introduced as an intermediary component between the gas piston and the closure parts. This buffer absorbs the recoil impulse and prevents direct impact, thereby eliminating bouncing and energy loss while ensuring reliable cartridge ignition. The buffer acts as a mediator that decouples the harmful recoil motion from the ignition mechanism.
2Ease of operation
If a closing spring sleeve is used to return the gas piston to starting position, then the gas piston is reset, but energy is removed from advancing closure parts causing bouncing
Solution Approach 1:
The buffer element serves as an intermediary that allows the gas piston to be returned to the starting position without directly impacting the closure parts. It absorbs the recoil energy and provides a controlled return motion, preventing the harmful bouncing effect while maintaining the ease of operation for resetting the gas piston.
Solution Approach 2:
The buffer element provides beforehand cushioning by being positioned to absorb the recoil impulse before it can transfer to the closure parts. This pre-cushioning prevents the harmful bouncing effect from occurring in the first place, ensuring smooth operation throughout the reset cycle.
3Reliability
If additional components are added to prevent bouncing, then bouncing is prevented, but the weapon structure becomes more complex and installation space is reduced
Solution Approach 1:
The buffer element is merged with the existing gas piston assembly, integrating the bouncing prevention function into the current structure. This combination approach adds minimal complexity while effectively preventing bouncing, as the buffer becomes part of the gas piston mechanism rather than a separate component.
Solution Approach 2:
The buffer element is nested within the existing weapon structure, specifically integrated into the gas piston assembly. This nesting approach allows the bouncing prevention function to be accommodated within the existing installation space without significantly increasing device complexity or requiring additional space.

AI summary
The invention relates to a gas piston for a weapon, which is characterized by a spring introduced in the gas piston and a plunger, which engages on one end of the spring, wherein the spring is supported by the other end at the end of the gas piston opposite the plunger. This gas piston can be a component of a gas piston assembly having a counter piston, which is for use in a weapon. The gas piston or the plunger is supported e.g. on the weapon housing. With the special construction of the gas piston or the gas piston assembly formed with same, the gas piston can be transferred from a working position into a resting position within a weapon housing of the weapon.
