Abstract (en)

A pneumatic firing device (90) includes a rear section (20) engaging a cylinder (10), a solenoid valve (25) engaging the rear section (20) from under, an adjusting element (30) disposed inside the rear section (20), a piston (40) disposed inside the cylinder (10) to form a first chamber (10a) and a second chamber (10b), an airflow guiding element (50) engaging the cylinder (10) at the front thereof, a moving rod (60) having a tail end engaging the piston (40) and a front end stretching through the cylinder (10) into the airflow guiding element (50) for operation control of the airflow guiding element (50), and a front section (70) engaging the front of the airflow guiding element (50). The solenoid valve (25) holds control of the operation of a pressure release channel (32) to change the pressure difference between the first and second chamber (10a), (10b), making the pressured air (A) entering a first passage (53) from a first guiding hole (512) of the airflow guiding element (50), pushing the delivery tube (80) to a firing position, flowing into a second passage (54) from a second guiding hole (513), and then firing a pellet (102) with strong airflow.
