A bolt mechanism (100) that is actuated by an electro-magnetic arrangement is provided for use within a pneumatic projectile launcher or marker (10). The electro-magnetic arrangement provides for rapid movement and a high degree of control over the bolt (118). Generally, an arrangement of electro-magnetic coils (120) is provided that exert a force on ferrous materials or permanent magnets (122) thereby causing the bolt (118) to reciprocate back and forth. Several embodiments are provided that disclose configurations having varied numbers of electro-magnetic coils (120), ferrous materials and permanent magnets (122) strategically placed within the breech (114) and bolt (118) of the marker (10), wherein energizing the coils (120) produces movement of the bolt (118). Further, the electro-magnetic bolt system (100) of the present invention is equally applicable to slide bolts (118) as well as rotary bolts (518). |
