초록 ▼

A projectile is propelled from the gun when a valve that controls the gas storage chamber of the gun is momentarily unseated, thereby admitting a short burst or charge of gas into the space immediately behind the projectile. The barrel that confines and controls the projectile during its movement out of the gun is itself driven rearwardly by spring action to accomplish unseating of the valve through an actuating stem at the rear of the barrel, and during such rearward movement of the barrel, the projectile is carried therewith so as to reduce the volume of the space behind the projectile in which the gas may expand before acting upon the projectile. After a predetermined amount of rearward movement, the projectile is released to thereby prevent interference with its propulsion from the gun, and return movement of the barrel forwardly after valve actuation is terminated short of its fully forward position, thereby minimizing the increase in the gas expansion space created by movement of the barrel and stem forwardly during firing. Stopping such forward movement in this way also positively precludes any opportunity for the barrel and actuating stem to oscillate in a rebounding manner between the spring that drives the barrel rearwardly and the spring controlling the valve, such activity otherwise causing a series of gas discharges after the projectile has already left the gun.

In a gas-powered gun having a gas expansion space defined between a forwardly disposed projectile and a rearwardly disposed control valve with respect to the direction of projectile travel out of the gun, and further having a barrel for the projectile and a rearwardly movable actuator in said space for momentarily unseating said valve to admit a sudden projectile-propelling charge of gas into said space, the improvement comprising: means other than said barrel for moving the projectile rearwardly with said actuator during said movement of the latter whereby to decrease the dimensions of said space and thereby reduce the amount of energy loss due to wasted volumetric expansion of said charge, said means including a retainer movable with said actuator and structure for releasing said retainer only after a predetermined amount of rearward movement by the projectile. In a gas-powered gun provided with an actuator that is spring-driven by a first compression spring in a rearward direction from a cocked position a valve-opening position for releasing a sudden charge of projectile-propelling gas and is then spring-returned by a second compression spring in the opposite forward direction toward said cocked position, the improvement comprising: means other than said springs for terminating said return movement of the actuator before the actuator can re-compress said first spring and at an intermediate position substantially free from spring force in either of said directions whereby to avoid additional, unintended valve openings caused by rebounding oscillations of the actuator the forwardmost position of said actuator for said return movement being rearward of said cocked position and being said intermediate position.
