AUTOMATIC FIREARM WITH INERTIAL AUTOMATIC LOADING SYSTEM

Abstract

The present invention relates to the field of military technology, and more particularly to an automatic firearm. Said firearm consists of a receiver, a barrel, a bolt carrier and a bolt, a bumper spring on the bolt carrier, a recoil spring between the bolt carrier and the rear wall of the receiver, a trigger mechanism, an ammunition feed mechanism, sighting equipment, a device for locking the bumper spring in a compressed state caused by the bolt carrier striking the front wall of the receiver or the barrel or the bolt via the bumper spring, and a mechanism for synchronizing the release of the bumper spring with the firing of a shot. Additionally, the firearm can be provided with an additional bumper spring between the bolt carrier and the rear wall of the receiver, and a lever for compressing and subsequently releasing said additional bumper spring in case the manual reloading in order to impart additional kinetic energy to the bolt carrier for the forward movement thereof, wherein said lever can be combined with a recharging handle. Additionally, the firearm can be provided with an additional device for locking the bumper spring in a compressed state caused by the bolt carrier striking the rear wall of the receiver via the bumper spring, and a lever for compressing and subsequently locking the bumper spring during the rearward movement of the bolt carrier in the case of manual reloading, wherein said lever can be combined with a recharging handle. The technical result provided by the above combination of features is the creation of a firearm having an inertial automatic loading system that functions reliably and consistently due to the increased reloading system working speeds and increased recovery of recoil energy.

Claims

1. The automatic firearm with inertial automatic reloading system, comprising a receiver, a barrel, a bolt carrier and a bolt, a bumper spring on the bolt carrier, a recoil spring between the bolt carrier and the rear wall of the receiver, a trigger mechanism, an ammunition feed mechanism, distinguished by the fact that it contains a device for locking the bumper spring in a compressed state caused by the impact of the bolt carrier to the front wall of the receiver or the barrel or the bolt via the bumper spring, a mechanism for synchronization of the release of the bumper spring with the firing of a shot.

2. The automatic firearm according to item 1, distinguished by the fact that it contains an additional bumper spring between the bolt carrier and the rear wall of the receiver.

3. The automatic firearm according to item 1, distinguished by the fact that it contains an additional device for locking the bumper spring in a compressed state, caused by the impact of the bolt carrier to the rear wall of the receiver via the bumper spring.

4. The automatic firearm according to item 1 through item 2, distinguished by the fact that it contains a lever for compressing at manual reloading of an additional bumper spring for the purpose of supplying the bolt carrier with additional kinetic power for moving forward, which may be combined with a handle for the gun reloading.

5. The automatic firearm according to item 1 through item 3, distinguished by the fact that it contains a lever for compressing at manual reloading of a bumper spring with the further locking, when the bolt carrier moves rearward, which may be combined with a handle for the gun reloading.

Description

[0014] The illustrative purposes, the FIG. 1 provides the design with the combined device for locking the bumper spring in a compressed state and the mechanism of synchronizing the release of the bumper spring with the firing of a shot, brought into operation by the simultaneous impact of the trigger to the trigger mechanism and mechanism guard.

[0015] The following is installed into a gun receiver (i. 1): a barrel (i. 2), a bolt carrier (i. 3), a recoil spring (i. 4), a trigger of a trigger mechanism (i. 5). The following is installed into a bolt carrier: a bolt (i. 6), a bumper spring (i. 7), a combined device for locking bumper spring in a compressed state and a mechanism for synchronization of the release of the bumper spring with the firing of a shot (i. 8), a pulling spring of combined device and mechanism (i. 9). The bolt is provided with a hammer (i. 10). The bullet is forced into the barrel (i. 11).

[0016] The design working order is identical to the one mentioned above.

[0017] The design of the mechanism for synchronization of the release of the bumper spring with the firing of a shot can be made under the principle of selection of a gun recoil moment.
