20100282232 | PNEUMATIC PAINTBALL GUN WITH VOLUME RESTRICTOR - A volume restrictor can be provided for a pneumatic paintball gun to reduce the volume of compressed gas available within a compressed gas storage area for a firing operation of the paintball gun. In one embodiment, the volume restrictor includes a body having a forward end and a rearward end. A forward sealing member can be arranged on the forward end to seal around a bolt of the paintball gun. A rearward sealing member can be arranged on the rearward end of the body to seal against a rearward endwall of the compressed gas storage area. By placing the volume restrictor within the compressed gas storage area of the paintball gun, the volume of compressed gas available for a firing operation is reduced, thereby requiring an increased operating pressure to achieve the same paintball velocity. The increased chamber pressure can result in a shorter recharge time and less velocity drop off in successive shots. A set of volume restrictors can be provided to permit a user to selectively adjust the available volume of compressed gas in the compressed gas storage chamber. Other configurations of volume restrictors are also contemplated within this invention, for example, such as non-sealing volume restricting rings having various wall thicknesses. | 11-11-2010 |
20140096758 | PNEUMATIC GUN HAVING MECHANICALLY-ACTUATED PNEUMATIC VALVE - According to principles of the present inventive concepts, a mechanically-actuated pneumatic valve can comprise an input port receiving compressed gas from a compressed gas regulator and one or more output ports. A face seal can be arranged in the valve body and be configured to move between two positions. In a first position, the face seal can permit compressed gas from the input port to be supplied to a first output port. In a second position, the face seal can vent compressed gas from the valve body through an exhaust port. An actuator, such as a pin or pin-shaped actuator, for example, can be configured and arranged to move the face seal from the first position to the second position, such as during a trigger pull. A contact surface could be configured to physically contact a surface of the pin-shaped actuator (either directly from the trigger or through one or more other components or mechanisms) and drive the face seal to its second position during actuation of the trigger. | 04-10-2014 |
