Abstract : A self-actuating slide valve system for launching a device in a fluid environment is provided. An interior channel, in which the device is positioned, is provided with first and second openings in its radial walls for allowing the passage of pressurized fluid into the interior channel. The first opening is located at least partially behind a tail end of the device and the second opening is located forward of the first opening. A sleeve is slidably fitted within a portion of the interior channel and around at least a portion of the device. The sleeve is movable between at least a first and second position. In the first position, the sleeve prevents the pressurized fluid from entering the interior channel through the first opening. In the second position, the sleeve allows the pressurized fluid to enter the interior channel through the first opening whereby the pressurized fluid can act on the tail end of the device to launch same through an axial opening of the interior channel.
