Abstract
An airgun for use with a projectile supply is described. A cam surface of the airgun and a bolt positioner of the airgun are configured so that rotation from a firing position to a reloading position causes a cam surface of the airgun to drive the bolt positioner through a passageway of the projectile supply to drive a projectile in the passageway to a position where pressurized gas in the firing location will thrust the projectile through the bore.
Claims18
An airgun comprising:
- a multi-shot projectile supply having:
- a housing defining a passageway extending along a supply axis configured to receive a projectile;
- and
- a carousel defining a plurality of projectile holders positioned about a central axis, a projectile holder of the plurality of projectile holders aligned with the passageway, wherein at least a portion of an edge of the carousel protrudes through an opening in the housing;
- and
- an air system having:
- a compression tube;
- and
- a compression piston having a piston surface and a compression seal with a mounting surface configured for mounting substantially about a perimeter of the compression piston and a seal face facing a transfer tube,
- wherein the compression piston compresses a gas in the compression tube from an initial volume to a reduced volume in response to firing the airgun and causes a pressure of the gas to reach a level sufficient to overcome a static and dynamic friction holding force acting to hold the projectile in a bore.
7 more elements
A multi-shot projectile supply comprising:
- a cover configured to prevent projectiles loaded in the multi-shot projectile supply from being loaded and unloaded at positions other than a firing position;
- and
- a carousel positioned within the cover, wherein at least a portion of an edge of the carousel protrudes through an opening in the cover, the carousel defining:
- a plurality of projectile holders positioned about a central axis;
- and
- a stop gap defined within the plurality of projectile holders;
- a stop positioned proximate a loading position of the multi-shot projectile supply, the stop configured to prevent rotation in a first direction of the carousel when a projectile is loaded in one of the plurality of projectile holders and to allow rotation in the first direction of the carousel when the plurality of projectile holders are empty;
- and
- a rotation spring configured to rotate the carousel in the first direction.

A multi-shot airgun comprising:
- a multi-shot projectile supply having:
- a cover configured to prevent projectiles loaded in the multi-shot projectile supply from being loaded and unloaded at positions other than a firing position;
- a carousel positioned within the cover and defining:
- a plurality of projectile holders positioned about a central axis;
- and
- a stop gap defined within the plurality of projectile holders;
- a stop positioned proximate a loading position of the multi-shot projectile supply, wherein the stop is configured to prevent rotation in a first direction of the carousel b the stop gap being blocked when a projectile is loaded in one of the plurality of projectile holders and to allow rotation in the first direction of the carousel when the plurality of projectile holders are empty;
- and
- a rotation spring configured to rotate the carousel in the first direction;
- and
- an air system comprising:
- a compression tube;
- and
- a compression piston having a piston surface and a compression seal with a mounting surface configured for mounting substantially about a perimeter of the compression piston and a seal face facing a transfer tube,
- wherein the compression piston compresses a gas in the compression tube from an initial volume to a reduced volume in response to firing the multi-shot airgun and causes a pressure of the gas to reach a level sufficient to overcome a static and dynamic friction holding force acting to hold the projectile in a bore.
