Cooling apparatus for the breech region of a weapon barrel
First Claim
1. A cooling apparatus for introducing a coolant fluid into a weapon barrel through a breech end thereof for cooling internal wall faces of a loading chamber of the barrel, comprising(a) a bellows having a circumference provided with a plurality of holes;
- said bellows having a retracted state and an elongated, tubular expanded state;
said bellows being introducible into the weapon barrel in said retracted state; and
(b) coolant driving means coupled to said bellows for introducing the coolant into said bellows to place said bellows into said expanded state and to force the coolant out of said bellows through said holes.

Abstract
A cooling apparatus for introducing a coolant fluid into a weapon barrel through a breech end thereof for cooling internal wall faces of a loading chamber of the barrel. The cooling apparatus includes a bellows having a circumference provided with a plurality of holes. The bellows has a retracted state and an elongated, tubular expanded state and is introducible into the weapon barrel in the retracted state. The cooling apparatus further has a coolant driving arrangement coupled to the bellows for introducing the coolant into the bellows to place the bellows into the expanded state and to force the coolant out of the bellows through the holes.

7. A combination comprising
(a) weapon barrel having a breech-side end, inner wall faces and a loading chamber situated in said breech-side end and defined by said inner wall faces; - and
(b) a cooling apparatus for introducing a coolant fluid into said weapon barrel through said breech end thereof for cooling said inner wall faces of said loading chamber;
said cooling apparatus comprising(1) a bellows having a circumference provided with a plurality of holes;
said bellows having a retracted state and an elongated, tubular expanded state;
said bellows being introducible into and removable from said weapon barrel in said retracted state; and
(2) coolant driving means coupled to said bellows for introducing the coolant into said bellows to place said bellows into said expanded state and to force the coolant out of said bellows through said holes against said inner wall faces;
said inner wall faces and said bellows in said expanded state define an annular clearance through which said coolant is expelled.- View Dependent Claims (8)
