Abstract
A liquid propellant gun having a chamber adapted to receive a projectile liquid propellant and having a breech area containing a fuel injection system and a valve internally thereof and a bolt which is chambered within said valve and adapted to move from a projectile load to a fire position. The movement of the bolt from projectile load to fire position is done in one movement and this is possible in that the valve is able to hold high-pressure, making unnecessary a forward jogging of the bolt before firing.
