The present invention relates to an individual subaquatic diving apparatus with self-contained recharging. This apparatus is constituted of a bottle pressurized with air by means of a manual pump integrated into the bottle or of a filler valve. This apparatus comprises a retention assembly that adapts to the back of the diver. The air under pressure in the bottle is transmitted to the diver via a hose and a single-stage pressure reducing valve that adjusts the suction pressure to the ambient pressure of the water. The pump integrated into the bottle is a high performance pump that makes it possible to reach a recharging capacity of several tens of bars without undue efforts. This manual pump with two chambers considerably improves the ratio between pressure, air flow, and the force exerted on the handle of the pump with respect to a conventional single-body pump.
Subaquatic self-contained breathing apparatus (15) including a bottle (1) and a carrying system adapted to fit in particular on the back of a diver, characterized in that it comprises a manual pump system integrated into the bottle (1).
Subaquatic self-contained breathing apparatus, characterized in that the primary chamber (CP) and the secondary chamber (CS) are functionally arranged in series.
Subaquatic self-contained breathing apparatus (15) according to any one of the preceding claims, characterized in that it comprises a charge and discharge valve (8).
Subaquatic self-contained breathing apparatus (15) according to any one of the preceding claims, characterized in that it comprises a system of telescopic or foldable feet (13) and (14).
Subaquatic self-contained breathing apparatus (15) according to any one of the preceding claims, characterized in that it comprises a system (30) for locking the pump.
Underwater self-contained breathing apparatus (1) according to any one of the preceding claims, characterized in that it includes an air supply hose (10) connected to the bottle (1) by a quick coupler (9), and in that the hose (10) is coupled to a pressure reducing valve (12) at its other end.
Underwater self-contained breathing apparatus (1) according to any of the preceding claims, characterized in that it includes an instrument (7) for measuring the internal pressure of the bottle.
