działanie karabinu maszynowego Browning .50 BMG http://giant.gfycat.com/OrangeNeighboringHummingbird.gif
geopiet Nov 30, 2017:
Browning 50BMG Heavy Machine Gun (1) At the instant of firing, the bolt is locked to the barrel extension and against the rear end of the barrel by the breech lock, which is on top of the breech lock cam and in the breech lock recess in the bottom of the bolt. When the cartridge explodes, the bullet travels out of the barrel; the force of recoil drives the recoiling groups rearward. During the first three-fourths of an inch, the recoiling groups are locked together. As this movement takes place, the breech lock is moved off the breech lock cam stop, allowing the breech lock depressors (acting on the breech lock pin) to force the breech lock down, out of its recess from the bottom of the bolt. At the end of the first three-fourths of an inch of recoil, the bolt is unlocked, free to move to the rear independent of the barrel and barrel extension.

napora ryglowa

Wg wyjaśnienia fachowca:

"Analogiczna część ckm wz. 30 *) nazywała się "napora ryglowa". Podczas odrzutu sworzeń rygla trafia na skośne krawędzie napór ryglowych i one "napierają" na tenże sworzeń, powodując obniżenie się rygla i tym samym odryglowanie zamka."

____
*) Ckm wz. 30 to polski przedwojenny klon Browninga M1917, z którego pochodzą rozwiązania mechanizmów późniejszego M2. Czyli w obu występują części o analogicznej budowie i zadaniach.

CALIBER .50 BROWNING MACHINE GUN M2

Hold one hand under the back of the oil buffer group and put the other hand under the front end, with the thumb along the breech lock depressor and the forefinger under the accelerator. Lift the accelerator up and slide the depressors into their tracks in the barrel extension, holding the back of the oil buffer tube in place with your little finger. - page 10


BREECH LOCK PIN
Holds the breech lock in the barrel extension; hits the depressors on the oil buffer body to force the breech lock down during recoil. - page 29


Remove the breech lock (2) by drifting out the breech lock pin (3). The breech lock holds the bolt to the barrel extension when the gun is in battery. On recoil, the breech lock pin hits the depressors on the oil buffer body and forces the breech lock down. - page 33
