摘要:
Exemplary embodiments are disclosed of paintball makers. In an exemplary embodiment, a paintball marker generally includes a housing including a wall defining a chamber having an axis and an open end. A valve assembly is within the chamber. The valve assembly may be coaxial with the chamber. The valve assembly may be configured for rotation about the axis of the chamber. The valve assembly may be configured to seal compressed gas while at rest and configured to seal and release compressed gas while in motion. Additionally, or alternatively, the revolving valve assembly may have a start position and a stop position which is located one revolution from initial movement out of the start position.

A pneumatic assembly for a paintball gun is provided. The pneumatic assembly includes a valve stem, and a bolt slidably mounted on the valve stem. The bolt includes at least one bolt port arranged through a sidewall of the bolt. A sealing member is provided on the valve stem in communication with an inner surface of the bolt. The bolt slides from a rearward position to a forward position along the valve stem. Compressed gas flows through the bolt port and through the bolt aperture to fire a projectile when the bolt is in the forward position. A paintball gun incorporating the pneumatic assembly is also provided.

摘要:
An improved paintball gun uses a pneumatic sear to hold the firing valve closed against the high pressure gas occupying the other side of the valve. In this manner, only one operation is required between depressing the trigger and the firing of the paintball gun because a double-acting cylinder is not required as an interface between the trigger depression and actuation of the valve. The paintball gun is also substantially faster than existing electro-pneumatic paintball guns because it uses a blow forward bolt, in which higher-pressure gas is held directly behind the bolt and has only one direction to travel during the firing of the paintball gun.
摘要:
A mechanism for a gas powered gun where a tubular bolt 10 of a paintball gun communicates with a cylinder 16 through bores 17 when in a forward, firing position, allowing compressed gas from the cylinder to expel a paintball. A port 20 whereby the cylinder communicates with a source of compressed gas is occluded by the bolt 10 except when a circumferential recess 23 in the bolt is in register with the port 20. By this arrangement only gas stored in the cylinder 16 is used to fire a paintball and the source of compressed gas is not in communication with the cylinder except when the trigger is released and the bolt 10 is withdrawn.
摘要:
A fluid pulsator for a compressed gun (10) or water gun (30) is provided having a housing (604) with a fluid inlet (607) and a fluid outlet (608), an internal tube (605) reciprocally coupled to the housing, and a sealing member (606) reciprocally mounted to the internal tube. The housing and internal tube define a rearward pressure chamber (632) and a forward fluid pressure chamber (631). The fluid pulsator also has means for actuating the movement of the sealing member that can be manually manipulated to vary the actuation rate of the pulsator.
