Abstract
A breech system for a firearm exhibits a breech which can be locked in its movement in the barrel block by at least one locking element, which is pressed against the rear end of the barrel by means of a breech spring surrounding the rigid barrel of the weapon, the barrel being enclosed with the exception of the front and rear apertures, whereby the breech spring is supported at the rear section of the barrel and at least one link element subjected to tension connects the front end of the breech spring and the breech. In order to guarantee precise function and in a manner which is safe for the user, by means of a simple arrangement which is reproducible in manufacture, a purely mechanical delay element is inserted in the link between the breech (10) and the breech spring (9).
Claims8
A breech system for a firearm, comprising:
- (a) a rigid barrel having a front section and a rear section and a front aperture and a rear aperture;
- (b) a barrel block having a front face and a rear face, a breech spring, a delay spring, a support bolt and a delay block having a front face and a rear face;
- (c) at least one locking element and at least one link element;
- and
- (d) a support bolt supported by a support bolt nest mount located on said barrel block;
- whereby said at least one locking element, is pressed against said rear section of said rigid barrel by said breech spring surrounding said rigid barrel, said breech spring being supported at said rear section of said rigid barrel;
- and
- whereby said at least one link element is subjected to tension and thereby connecting said front end of said breech spring and the breech, creating mechanical delay between said at least one link element between the breech and said breech spring;
- and
- the breech system further including said mechanical delay comprising said delay spring said support bolt, and said delay block,
- whereby said support bolt supported in said support bolt nest mount of said barrel block, wherein said rear face of said barrel block together with said front face of said delay block creates a V-shaped mounting open towards said rigid barrel, and further whereby said delay block is moved towards said rigid barrel by said delay spring supported at the breech.
