Gas spring for a revolver cannon or breech cannon
The characteristic of one or more of the gas springs themselves used in a revolver cannon or breech cannon is adjusted while the system is in operation. This is done by a separate, self-contained system, which can adjust the gas spring from hard to soft, for example, and back to harder/hard and can thus adjust the characteristic of the gas spring without the loss of gas. In the simplest embodiment, this system has two additional elements, preferably a reserve tank and a connecting line that connects the reserve tank to the gas spring via a valve.
1. A gas spring for a revolver cannon or a breech cannon, comprising:
a cannon;
a piston/cylinder arrangement; and
an additional gas system integrated with the piston/cylinder arrangement so as to be useable to adjust the spring characteristic of the gas spring during operation of the cannon, the additional gas system being operative to automatically regulate a rate of fire of the cannon, whereby the spring characteristic of the gas spring is adjusted from hard to soft and back to hard so that the spring characteristic of the gas spring is adjusted without gas losses based on the rate of fire of the cannon.
2. The gas spring according to claim 1 , wherein the additional gas system has at least one reserve tank which is connected to the gas spring by a valve and a connecting line.
3. The gas spring according to claim 2 , wherein the system supports charging, and the reserve volume of the reserve tank being connected to the system for charging.
4. The gas spring according to claim 2 , having a single reserve tank.
5. The gas spring according to claim 1 , wherein the system is switchable between two operating modes.
6. The gas system according to claim 5 , wherein the system supports two different operating modes during firing, where the first operating mode is settable for a lower rate of fire, and the second operating mode is settable for a higher rate of fire.
