Title:
PROJECTILE FIRING DEVICE
Document Type and Number:
WIPO Patent Application WO/1995/011724
Kind Code:
A1
Abstract:
The proposed projectile firing device comprises a reservoir (1) for compressed gas and an outlet chamber (2) connected to the reservoir (1) via a primary fast response valve (3) controlled by a trigger valve (17) which is provided with a hammer device (5). The primary valve (3) contains a seat (6) provided with at least two annular ledges (7, 8) separated by a space and forming an annular flow-through duct (9) between the reservoir (1) and the outlet chamber (2), the said duct narrowing towards the latter; a hollow cylindrical body (13) provided with an outlet aperture (15) on the same side as the flow-through annular duct (9) and coaxial with it; and a displaceable splitter (10) mounted telescopically on the cylindrical body (13) on the same side as the outlet aperture (15). The trigger valve (17) comprises a first chamber (18) which communicates with the hollow space inside the cylindrical body (13) of the primary valve (3); a second chamber (19) which communicates with the atmosphere; a flow-through annular duct (20) between chambers (18) and (19), tapering in the direction from the first chamber (18) towards the second chamber (19), and provided with at least two annular ledges (28 and 29) separated by a space, the said ledges forming a seat (30); a hollow cylindrical body (24) which is mounted in the first chamber (18), connected via a reduction valve (35) to the compressed gas source and via the hammer device (5) to the atmosphere, and provided with an outlet aperture (26) and a displaceable splitter (21) mounted telescopically on the cylindrical body (24) on the same side as the outlet aperture (26).
