Abstract
An improved paintball gun uses a low-pressure 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.
Claims28
A compressed gas driven gun comprising;
- a cylinder comprising a piston and a valve pin slidable coaxially therein;
- compressed gas at a first pressure that biases the piston in a first direction;
- compressed gas at a second pressure that biases the piston in a second direction, and overcomes a force exerted by the first pressure biasing the piston in the first direction so that the piston moves in the second direction;
- and
- a valve that, in response to a signal, decreases the second pressure enough to allow the compressed gas at a first pressure to bias the piston in the first direction, which in turn releases the compressed gas at a first pressure to fire a projectile from the gun.
A compressed gas driven gun comprising;
- a bolt slidable within a cylinder in a first direction under a first pressure exerted by compressed gas, and slidable within the cylinder in a second direction under a second pressure exerted by the compressed gas, wherein the first pressure acts on a first surface area smaller than that of a second surface area acted on by the second pressure;
- and
- wherein when the bolt moves in one of the two directions, a paintball is driven from the gun by the compressed gas.
A compressed air driven gun comprising a power switch that controls electricity driven functions within the gun including the signal, said switch located within a recess within the gun.
