System for feeding with pressurised fluid an ejection piston of a launching tube of a weapon on a submarine

摘要

The system has a launching valve interposed between a pressurized fluid source and a rammer. The valve includes a valve body (5) in which a removable valve (6) is mounted during launching of a weapon by a control unit between a closing position and an opening position of the valve to supply pressurized fluid to the rammer. The removable valve is associated with a braking unit (8) including a fluidic speed reducer with two fluid chambers (9, 10) connected together by a diaphragm unit for controlling the fluid. The diaphragm unit is variable according to the position of the removable valve.
