20090056693 | PROJECTILE LAUNCHING APPARATUS - Disclosed is a projectile launching apparatus capable of launching a projectile, such as a pellet, a BB, an arrow, a dart and a paintball. The projectile launching apparatus includes a motor driven linear motion converter, a cylinder, a breech assembly and a compression valve arrangement. The linear motion converter converts a rotational movement of a motor into a linear movement of a piston by a gear reduction mechanism. The linear movement of the piston within the cylinder compresses a gas with a high compression exponent. The compressed gas is further released into a barrel of the breech assembly through the compression valve arrangement. The compressed gas expands in the barrel causing a projectile to be launched from the barrel with a force of the compressed gas. | 03-05-2009 |

At the predetermined pressure, the valve arrangement assumes an open position for communicating the compressed gas to the second cylinder, thereby causing the second piston to move linearly and enabling the anvil to drive the fastener into the workpiece. During a return stroke, at a predetermined position of the first piston in the first cylinder, the valve arrangement assumes the open position for communicating a vacuum created in the first cylinder to the second cylinder and thereby causing the second piston and the anvil to retract to their initial positions. | 08-26-2010 |
