Benefits of technology
[0028] The foregoing and other features and advantages of the invention will become more readily apparent from the following
Problems solved by technology
Unfortunately, however, this configuration has several disadvantages when used for CO2 systems, which generally have smaller valves.
Because of this, the on / off valve 100A is not sufficiently reliable.
Some problems with this embodiment, however, include the difficulty of machining an o-ring retention area in the entry port 213 of the outlet 212, and the corresponding increase in expense.
The body 202B could be formed in two halves and then secured together to reduce the complexity of the required machining, but the body 202B would then be bulkier and still more expensive.
Despite the improvements in on / off valves provided by Perry et al., existing on / off valves have not provided an integrated fill nipple, such as is used for filling high pressure compressed gas tanks.

Embodiment Construction
[0046] A preferred embodiment illustrating the present inventive principles will now be described with reference to the accompanying figures. More specifically, FIG. 12 is a schematic side view of a combination fill nipple and on / off valve 1000 according to a presently preferred embodiment of the present invention, shown connected to a paintball gun 50. FIG. 13 is a schematic perspective view of the combination fill nipple and on / off valve 1000 of FIG. 12, shown connected to a compressed gas tank 60. In FIG. 13, the valve body 1001 is shown transparently to permit viewing of a fill nipple and valve spool 1010. FIGS. 14 and 15 are enlarged perspective views of the fill nipple and on / off valve 1000 shown in the “off” and “on” positions, respectively. And finally, FIG. 16 is a cross-sectional view of the integrated on / off valve and fill nipple 1000 of FIG. 13.
[0047] Referring to FIGS. 12-16, according to a preferred embodiment of the present invention, an on / off valve and integrated f...

An integrated fill nipple and on / off valve for a paintball gun preferably includes a body. The body preferably includes a gas inlet to receive a gas from a compressed gas source and a gas outlet to transmit the gas to the paintball gun. The body also preferably contains a plug cavity for receivingly engaging a plug. The plug preferably includes a flow aperture for transmitting the gas from the inlet aperture to the outlet aperture. An actuator preferably controls the plug position and, hence, a supply of gas through the flow aperture. A fill nipple is also preferably arranged on the plug. Movement of an actuator between an “on” position and an “off” position can be configured to open and close the on / off valve. In an open position, the flow aperture is preferably positioned in communication with the inlet aperture to permit a flow of gas from the inlet aperture to the outlet aperture. Conversely, in a closed position, gas flow between the gas inlet and the gas outlet is preferably prevented. Filling of the compressed gas tank through the fill nipple can be permitted in either position or in only one of the positions.
Description
RELATED APPLICATION DATA [0001] This application claims priority from U.S. Provisional Patent Application Ser. No. 60 / 498,917, filed Aug. 28, 2003, which hereby incorporates by reference.BACKGROUND OF THE INVENTION [0002] This invention relates generally to paintball guns. More specifically, this invention relates to a paintball gun on / off valve and fill nipple for selectively controlling a supply of gas from a compressed gas source to a compressed gas storage tank and from a compressed gas storage tank to a paintball gun. [0003] A reliable on / off valve for selectively supplying a flow of compressed gas to a paintball gun from a compressed gas tank is shown and described in U.S. Pat. No. 6,260,821 B1 (the contents of which are incorporated herein by reference in their entirety), which issued Jul. 17, 2001 to Perry et al., and was assigned to Smart Parts, Inc. In particular, the on / off valve shown and described in Perry et al. overcame reliability problems with preexisting on / off val...
