Cost effective paintball gun system
View Patent ↗A paintball gun system comprises a bolt defining a propellant passageway and a gun body defining the following elements: a receptacle for receiving the bolt, a firing charge storage chamber adjacent to but separate from the bolt receptacle, a gas inlet port, a first passageway between the storage chamber and the receptacle, a second fixed passageway between the gas inlet and the receptacle. The first passageway communicates with a first flow opening into the receptacle and the second passageway communicates with a second flow opening into the receptacle. The bolt is axially movable between a chargeup position and a firing position. In the chargeup position, the bolt and the body together define a confined flow circuit between the first opening and the storage chamber. In the firing position, the bolt and the body together define a confined flow circuit between the storage chamber and the discharge inlet.
1. A paintball gun system comprising:
a bolt having a proximal end and a distal end and defining a firing passageway from a discharge inlet in the proximal end to a discharge outlet in the distal end;
a body defining a receptacle for receiving the bolt, a firing charge storage chamber adjacent to but separate from the bolt receptacle, a gas inlet port, a first passageway between the storage chamber and the receptacle such that the storage chamber communicates with a first fluid opening into the receptacle, a second passageway between the gas inlet and the receptacle such that the gas inlet communicates with a second flow opening into the receptacle;
wherein the bolt is axially movable within the receptacle between a chargeup position in which the bolt and the body together define a confined flow circuit between the first fluid opening and the storage chamber, and a firing position in which the bolt
and the body together define a confined flow circuit between the storage chamber and the discharge inlet.
2. The paintball gun according to claim 1 wherein the storage chamber has an adjustable volume.
3. The paintball gun according to claim 1 wherein the storage chamber has an adjustable volume provided by a movable wall partially defining the storage chamber.
4. The paintball gun according to claim 1 wherein the receptacle has an open end and a closed end, the bolt is biased towards the closed end with a spring mechanism and the spring mechanism includes a compression level adjustment.
5. The paintball gun according to claim 1 wherein the receptacle has an open end and a closed end portion and the bolt is biased towards the closed end portion with a spring housed in the closed end portion.
6. The paintball gun according to claim 5 wherein the closed end portion has a threaded cap linked to the spring for adjusting the compression level of a spring.
7. The paintball gun according to claim 1 wherein the gun body defines a third passageway between the storage chamber and the receptacle terminating in a third flow opening into the receptacle.
8. The paintball gun according to claim 1 wherein the confined flow circuit defined in the chargeup position includes the first flow opening.
9. The paintball gun according to claim 1 the gun body defines a third passageway between the storage chamber and the receptacle terminating in a third flow opening into the receptacle, and the confined flow circuit of the discharge position includes the third passageway.
