Abstract
An air gun includes an air pump with a pumping piston mounted to reciprocate within a pump cylinder, which is mounted on the barrel of the gun to pivot about an axis transverse to the longitudinal axis of the barrel so that as the pump cylinder is moved back and forth around the pivot, the cylinder and piston reciprocate relative to each other to pump air into a high pressure housing carried by the pump cylinder. A discharge conduit is also provided for releasably connecting the high pressure to the breach end of the barrel when the pump is moved toward the barrel. A firing valve in the discharge conduit releases air from the high pressure housing in to the breach end of the barrel.

An air gun comprising:
- a barrel with a breech end and a muzzle end;
- an air pump including a pump cylinder and a pumping piston mounted to reciprocate within the cylinder, the pump cylinder being mounted on the barrel to pivot about an axis transverse to the longitudinal axis of the barrel, so that as the pump cylinder is moved back and forth around the pivot, the cylinder and piston reciprocate relative to each other to pump air into a high pressure housing carried by the pump cylinder;
- a conduit for releasably connecting the high pressure housing to the breech end of the barrel when the pump is moved toward the barrel;
- and
- a firing valve in the conduit for releasing air from the high pressure housing into the breech end of the barrel.
An air gun comprising:
- a barrel with a breech end and a muzzle end;
- an air pump including a pump cylinder and a pumping piston mounted to reciprocate within the cylinder, the pump cylinder being mounted on the barrel to pivot about an axis transverse to the longitudinal axis of the barrel between a first position with the pump cylinder substantially parallel to the barrel and a second position with the pump cylinder transverse to the barrel, so that as the pump cylinder is moved back and forth around the pivot, the cylinder and piston reciprocate relative to each other to pump air into a high pressure housing carried by the pump cylinder;
- a conduit for releasably connecting the high pressure housing to the breech end of the barrel when the pump cylinder is moved toward the barrel to the first position;
- a firing valve in the conduit for releasing air from the high pressure housing into the breech end of the barrel;
- a bolt mounted on the gun at the breech end of the barrel to slide longitudinally between a loading position and a firing position;
- and
- a lock on the gun responsive to the movement of the bolt to the firing position to lock the pump cylinder in the first position.
