Abstract

L'invention est du domaine des appareils respiratoires. Elle vise plus précisément un appareil de pompage de gaz respiratoire pour la plongée qui comprend un certain nombre de cylindres de pompe à piston alternatif, un collecteur commun pour recevoir le gaz respiratoire refoulé par chacun desdits cylindres de pompes et une source de force motrice pour actionner les pistons des pompes, cet appareil étant caractérisé par le fait qu'il comporte au moins quatre pistons opérant successivement avec des déphasages mutuels se recouvrant partiellement entre deux refoulements successifs de gaz par les pistons. Cet appareil est capable d'alimenter le plongeur avec un courant regulier de gaz respiratoire.The invention relates to the field of breathing apparatus. It relates more specifically to a breathing gas pumping apparatus for diving which comprises a certain number of reciprocating piston pump cylinders, a common manifold for receiving the respiratory gas delivered by each of said pump cylinders and a source of motive force for actuating the pistons of the pumps, this apparatus being characterized by the fact that it comprises at least four pistons operating successively with mutual phase shifts partially overlapping between two successive discharges of gas by the pistons. This device is capable of supplying the diver with a steady stream of respiratory gas.
