An air reservoir system is provided that includes a switchable valve to direct input air to an air reservoir, or stored air in the air reservoir to a firing pathway. Various example embodiments of the present general inventive concept may also include an air-saver system to maintain a minimum air pressure in the air reservoir during a firing operation.

The present disclosure is directed to an apparatus and method of directing a portion of a pressurize gas flow through a port in the breech after is leaves a bolt in a projectile launching device, such as a paintball marker, to perform additional functions in parallel with launching the projectile from the launching device. For example, the additional function can be a mechanism to prevent, or free, any potential bottlenecks of projectiles at that location when using a gravity fed hopper, for example. An agitating device is at least partially disposed in the outlet of a hopper. A bolt, having key groove or gas port, is configured to bleed air to a port in the breech that is used to fire a loaded projectile, the air is provided from a pressurized air source. An actuator moves the agitating device when air is bled through the key groove and the port.

A dart delivery apparatus including a handle, trigger, barrel, and frame comprising a dart chamber, a pressure control apparatus including a gas source port, an adjustable pressure control apparatus chamber, a gun port configured to attach to the frame, an expansion chamber, an adjustable pressure regulator configured to be actuated by a user to permit pressurized gas to flow from the gas source port, through the pressure control apparatus chamber, and into the gun port and the expansion chamber, and a shot volume modification apparatus configured to change the volume of the expansion chamber into which pressurized gas may expand.

An air-soft gun includes a grip; a high-pressure air canister disposed in the grip; and a remaining compressed air release device including a channel member threadedly secured to an end of the air canister and including an axial channel and a sealing ring; a rotatable cap releasably secured to the channel member; a biasing member fastened between the cap and the channel member; a striker including a needle on a first end, an internal passageway, an inlet proximate the needle and communicating with the passageway, an outlet proximate a second end and communicating with the passageway, internal threads on the passageway proximate the second end, and a threaded fastener driven through the cap into the internal threads to secure the cap to the striker. The inlet is blocked by the sealing ring in an inoperative position.

An air flow adjusting device of air gun includes an adjusting assembly having an adjusting knob and a locking seat; a piston sleeve provided with a rod body inserted into the locking seat and threaded with the adjusting knob; a spring arranged between the locking seat and a base of the rod body. One end of the adjusting knob is locked to the locking seat. By rotating the adjusting knob, the relative locking position of the adjusting knob and the locking seat can be changed, and the total length of the piston sleeve and the adjusting assembly can be adjusted; thereby, the adjusting knob can be rotated by to defining a slot in the piston seat, and the function of adjusting the air flow rate can be achieved without using any tool, so that the operation of adjusting the air flow can be simplified, which improves the operational convenience of the device.

A blaster for shooting projectiles that includes a housing that defines a housing interior, and a variable velocity barrel assembly positioned in the housing interior. The variable velocity barrel assembly includes a barrel that defines a barrel axis and a barrel interior. The barrel includes an exit opening at a distal end thereof. At least a first opening communicates the barrel interior with an exterior of the barrel. The first opening is defined through a side wall of the barrel. A slider member that includes a cylindrical portion that surrounds the barrel is movable axially along the barrel between a maximum velocity position where the cylindrical portion covers the first opening and a minimum velocity position where the slider member does not cover the first opening.

A variable velocity pneumatic launcher including at least one chamber filled with a projectile. The launcher includes a ballast chamber filled with pressurized air selectively released to propel a projectile from the launcher's barrel. The launcher includes a firing chamber filled with ambient air and a ballast chamber filled with pressurized air. A piston rod extends between the chambers and attaches to a firing piston and a ballast piston located inside the firing chamber and ballast chamber, respectively. The rod is connected to an adjustable velocity valve which controls the amount of longitudinal movement of the rod. When the trigger is activated, a portion of the pressurized air from the ballast chamber is delivered to the firing chamber. Because the surface area of the firing piston is greater than the ballast piston's surface area, the force exerted on the firing piston is sufficient to shift or displace the ballast piston and allow pressurize air to be released into the upper chamber containing the projectile.
