Abstract
System for a delayed-opposed-piston gas action assembly. Specifically, the system is comprised of a bolt, a bolt carrier, a gas block, a bolt piston, and a vent piston. Each piston will have a corresponding piston cup that will act on the piston from the gas discharged from the round. Each piston will also have a corresponding spring to bring the piston back to its original position after the gas has dissipated from the system. During the process of the firearm being discharged, the two pistons will act on the bolt carrier, causing the casing of the round to be ejected from the firearm, and a new round to be loaded into the firearm, so that the firearm can be discharged again.

(10) In the following description, and for the purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding of the various aspects of the invention. It will be understood, however, by those skilled in the relevant arts, that the present invention may be practiced without these specific details. In other instances, known structures and devices are shown or discussed more generally in order to avoid obscuring the invention. In many cases, a description of the operation is sufficient to enable one to implement the various forms of the invention, particularly when the operation is to be implemented in software. It should be noted that there are many different and alternative configurations, devices and technologies to which the disclosed inventions may be applied. The full scope of the inventions is not limited to the examples that are described below.
(11) In FIG. 1A through FIG. 1E, a non-limiting embodiment of the delayed-opposed-piston gas action assembly is shown. The embodiment shows two serial pistons: the bolt piston 7 and the vent piston 9. FIG. 1A shows the state of the assembly before the firearm is discharged. The bolt carrier 1 has already loaded the round 3 in the chamber 2. Once the firearm is discharged, as shown in FIG. 1B, the gas will move from the barrel 6 through the gas port 5 inside the gas block 4 and act on the bolt piston 7 via the bolt piston cup 8, and the vent piston 9 via the vent piston cup 10. When the bolt piston 7 is acted on, the bolt piston spring 26 is compressed. When the vent piston 9 is acted on, the vent piston spring 27 is compressed. Once pushed back, the bolt piston 7 will lock into place via the lock 16. Once all of the gas has been vented through gas vent 11, the vent piston spring 27 will act on the vent piston 9, moving the vent piston 9 towards the bolt carrier 1. The vent piston 9 will couple via latch 14 to the bolt carrier 1 and act on the bolt carrier 1, causing the casing 12 of the discharged round to be ejected from the firearm. This is shown in FIG. 1C. The latch actuator 15 will act on the latch 14 to uncouple the vent piston 9 from the bolt carrier 1. The vent piston 9 will then act on lock 16 to unlock the bolt piston 7 as shown in FIG. 1D. At this point the vent piston 9 is back in the starting position. Once unlocked, the bolt piston 7 is then acted on by the bolt piston spring 26, which moves the bolt piston 7 back into the starting position. When the bolt piston 7 is acted on by the bolt piston spring 26, this acts on the bolt carrier 1 bringing it back to the bolt carrier's 1 starting position, as well as loading a new round 13 into the firearm. Once everything is complete, the firearm is ready to be discharged again, as shown in FIG. 1E. The non-limiting embodiment shown in FIG. 1A through FIG. 1E would be the optimal embodiment for the delayed-opposed-piston gas action assembly.
(12) In FIG. 2, a non-limiting embodiment of the delayed-opposed-piston gas action assembly is shown. This embodiment shows two opposed pistons: the long stroke bolt piston 21 and the long stroke vent piston 23. In this embodiment, both pistons will be acted on by the discharged gas at the same time, instead of in serial as in FIG. 1A through FIG. 1E. In this embodiment, there is the long stroke bolt piston cup 22 and the long stroke vent piston cup 24. FIG. 2 shows the state of the assembly before the firearm is discharged. The bolt carrier 1 has already loaded the round 3 in the chamber 2. Once the firearm is discharged, the gas will move from the barrel 6 through the gas port 5 inside the gas block 4 and act on the long stroke bolt piston cup 22 and the long stroke vent piston cup 24. Both piston cups are acted on at the same time. The long stroke bolt piston cup 22 will then act on the long stroke bolt piston 21, at the same time the long stroke vent piston cup 24 will act on the long stroke vent piston 23. When the long stroke bolt piston 21 is acted on, the bolt piston spring 26 is compressed. When the long stroke vent piston 23 is acted on, the vent piston spring 27 is compressed. Once pushed back, the long stroke bolt piston 21 will lock into place via the lock 16. At the same time, the vent piston spring 27 will act on the long stroke vent piston 23, moving the long stroke vent piston 23 towards the bolt carrier 1. The long stroke vent piston 23 will couple via latch 14 to the bolt carrier 1 and act on the bolt carrier 1, causing the casing of the discharged round to be ejected from the firearm. The latch actuator 15 will act on the latch 14 to uncouple the long stroke vent piston 23 from the bolt carrier 1. The long stroke vent piston 23 will then act on lock 16 to unlock the long stroke bolt piston 21. At this point the long stroke vent piston 23 is back in the starting position. Once unlocked, the long stroke bolt piston 21 is then acted on by the bolt piston spring 26, which moves the long stroke bolt piston 21 back into the starting position. When the long stroke bolt piston 21 is acted on by the bolt piston spring 26, this acts on the bolt carrier 1 bringing it back to the bolt carrier's 1 starting position, as well as loading a new round into the firearm. Once everything is complete, the firearm is ready to be discharged again.
(13) In FIG. 3, a non-limiting embodiment of the delayed-opposed-piston gas action assembly is shown. This embodiment shows two opposed pistons: the short stroke bolt piston 17 and the short stroke vent piston 19. In this embodiment, both pistons will be acted on by the discharged gas at the same time, instead of in serial as in FIG. 1A through FIG. 1E. In addition, these pistons are short stroke. This means that the piston cups are separate pieces than the pistons themselves. When the firearm is discharged, the pistons cups will throw the pistons into the correct position, rather than act on them as one solid piece. As such, in this embodiment, there is the short stroke bolt piston cup 18 and the short stroke vent piston cup 20. FIG. 3 shows the state of the assembly before the firearm is discharged. The bolt carrier 1 has already loaded the round 3 in the chamber 2. Once the firearm is discharged, the gas will move from the barrel 6 through the gas port 5 inside the gas block 4 and act on the short stroke bolt piston cup 18 and the short stroke vent piston cup 20. Both piston cups are acted on at the same time. The short stroke bolt piston cup 18 will then throw the short stroke bolt piston 17, at the same time the short stroke vent piston cup 20 will throw the short stroke vent piston 19. Once thrown back, the short stroke bolt piston 17 will lock into place via the lock 16. At the same time, the vent piston spring (not shown in this figure) will act on the short stroke vent piston 19, moving the short stroke vent piston 19 towards the bolt carrier 1. The short stroke vent piston 19 will couple via latch 14 to the bolt carrier 1 and act on the bolt carrier 1, causing the casing of the discharged round to be ejected from the firearm. The latch actuator 15 will act on the latch 14 to uncouple the short stroke vent piston 19 from the bolt carrier 1. The short stroke vent piston 19 will then act on lock 16 to unlock the short stroke bolt piston 17. At this point the short stroke vent piston 19 is back in the starting position. Once unlocked, the short stroke bolt piston 17 is then acted on by the bolt piston spring (not shown in this figure), which moves the short stroke bolt piston 17 back into the starting position. When the short stroke bolt piston 17 is acted on by the bolt piston spring (not shown in this figure), this acts on the bolt carrier 1 bringing it back to the bolt carrier's 1 starting position, as well as loading a new round into the firearm. Once everything is complete, the firearm is ready to be discharged again.
(14) In FIG. 4, a non-limiting embodiment of the delayed-opposed-piston gas action assembly is shown. This embodiment shows two serial pistons: the bolt piston 7 and the vent piston 9. In this embodiment, the bolt piston 7 will not lock in place after a discharge but will have more mass in the form of a weighted bolt piston head 25, such that the bolt piston 7 is starting to return after the vent piston 9 has finished its cycle and decoupled from the bolt carrier 1. FIG. 4 shows the state of the assembly before the firearm is discharged. The bolt carrier 1 has already loaded the round 3 in the chamber 2. Once the firearm is discharged, the gas will move from the barrel 6 through the gas port 5 inside the gas block 4 and act on the bolt piston 7 via the bolt piston cup 8 and the vent piston 9 via the vent piston cup 10. When the bolt piston 7 is acted on, the bolt piston spring 26 is compressed. When the vent piston 9 is acted on, the vent piston spring 27 is compressed. Once all of the gas has been vented through gas vent 11, the vent piston spring 27 will act on the vent piston 9, moving the vent piston 9 towards the bolt carrier 1. The vent piston 9 will couple via latch 14 to the bolt carrier 1 and act on the bolt carrier 1, causing the casing of the discharged round to be ejected from the firearm. The latch actuator 15 will act on the latch 14 to uncouple the vent piston 9 from the bolt carrier 1. At this point the vent piston 9 is back in the starting position. By this time, the bolt piston's 7 direction of travel has been reversed by the bolt piston spring 26. When the bolt piston 7 returns to the bolt piston's 7 starting position, the bolt piston 7 acts on the bolt carrier 1 bringing the bolt carrier 1 back to the bolt carrier's 1 starting position. When the bolt carrier 1 is brought back to its starting position, a new round is loaded into the firearm. Once everything is complete, the firearm is ready to be discharged again. This embodiment will not fare as well as the embodiment shown in FIG. 1A through FIG. 1E as variations in gas output between rounds can cause the timing between the pistons to be off, causing the firearm to jam.
(15) The non-limiting embodiments shown through FIG. 1A through FIG. 4 can also be permutated with each other. For example, the short stroke pistons found in FIG. 3 could be utilized in FIG. 1A through FIG. 1E, FIG. 2, or FIG. 4. Furthermore, the weighted piston found in FIG. 4 could be utilized in FIG. 1A through FIG. 1E, FIG. 2, or FIG. 3. Additionally, the opposed piston configuration found in FIG. 2 and FIG. 3 could be utilized in FIG. 1A through FIG. 1E or FIG. 4. Finally, a single short stroke piston found in FIG. 3 could replace just one of either of the pistons in FIG. 1A through FIG. 1E, FIG. 2, or FIG. 4.
