Abstract
A projectile launching device has a knock-open valve that is opened when forced by a hammer to release compressed air and launch a projectile from the device. The projectile launching device has a force control device between the hammer and the knock-open valve that is configured and positioned to provide force translation and control, allowing forces acting on a knock-open valve to be manipulated independently of the speed profile and mass of the hammer. A bolt is used to load a projectile into the barrel before it is launched. Where the hammer is configured to move with the bolt, the force control device allows forces acting on a knock-open valve to be manipulated independently of the speed profile and mass of the hammer and the bolt. The force control device can be a cam surface or a lever, or a lever having a cam surface.
