Portable electric motor driven compressed air projectile launcher

An electrically-driven compressed air gun used for firing a projectile, said gun comprising:

• a power source to power a motor;
• a sensor to obtain information corresponding to said motor;
• a control circuit for controlling the motor using said information from the sensor;
• a piston to compress air and driven by said motor;
• a cylinder in which the piston reciprocates;
• a compression valve;
• the piston being driven linearly to compress air in the cylinder against said compression valve;
• a bolt for chambering said projectile;
• a projectile inlet port;
• a second valve formed by movement of the bolt against the projectile inlet port;
• a barrel to receive the projectile;
• an air passageway interdispersed between said cylinder and said second valve;
• an apparatus to open said compression valve to allow air compressed by said piston to flow thru said compression valve and air passageway to said projectile.

An electrically-driven compressed air gun used for firing a projectile, said air gun comprising:

• a power source to power a motor;
• a sensor to obtain information from said motor;
• a control circuit for controlling the motor using information from the sensor;
• a reduction apparatus;
• a rack pinion coupled to said reduction apparatus;
• a rack which engages said rack pinion;
• a piston coupled to said rack;
• a cylinder for the piston to reciprocate to compress air;
• a barrel to receive the projectile;
• an air passageway between said cylinder and said projectile a compression valve interdisposed between said cylinder and said air passageway;
• wherein said air compression valve releases air from said cylinder while said rack is still engaged with said rack pinion.
