A semi-closed circuit gas recycling scuba diving breathing apparatus having a breathing loop. The breathing loop has a breathing bag to be supplied by at least one gas tank and a recycling chamber. The gas tank is connected to an inlet of the breathing bag by a first duct and a second duct having respectively a demand regulator and a fixed nozzle configured to deliver respectively a first gas input and a second gas input to the breathing bag. Advantageously, the apparatus has a third duct having a gas flow regulator configured to deliver at a variable mass flow, a third gas input to the breathing bag, and a diving condition sensor, configured to measure a physiological parameter of the diver or the depth. The apparatus is advantageously configured to make the variable mass flow vary according to data of the sensor to optimise the consumption of gas.

Breathing apparatus for scuba diving with semi-closed circuit gas recycling

Device comprising a demand valve () for delivering breathable gas to a diver and a fluidic connector () that can be selectively connected to the demand valve (), the demand valve () comprising a breathable gas supply inlet (), characterized in that the demand valve () and/or the fluidic connector () comprise a blocking device () for selectively blocking the connector () on the demand valve () when the connector () is fastened to the demand valve () via the catching members (), the blocking device () being selectively moveable and/or deformable between a first configuration of blocking relative movement between the demand valve () and the connector (), and a second configuration of unblocking, allowing relative movement between the demand valve () and the connector ().

Demand valve device for use by diverse and selectively connectable fluidic connector

Device for supplying breathing gas, particularly for a mouthpiece of a diver, including a casing incorporating, between an inlet orifice for the supply gas and an orifice or the outlet of the gas for the purpose of breathing: a pressure-reducing valve system having a member for controlling the force necessary to open the valve, a member for controlling the flow rate of the gas let into the outlet orifice, the supply device also including a manually actuatable control element capable of interacting with the control member in order to adjust the force necessary to open the valve, characterized in that the control element is capable of interacting also with the member for controlling the flow rate of gas in order to ensure both the adjustment of the force for opening the valve and the adjustment of the flow rate of outlet gas.

Device for supplying breathing gas, particularly for mouthpiece of a diver

A reducing valve, which includes a water trap, especially useful in diving.

Breathable pressurized-gas reducing valve

The body of the valve has two outlets whose axes are offset in the direction of the axis of the mounting base by a distance greater than 5 mm, typically between 20 and 60 mm, the spacing between the outlet axes being greater than 60 mm and typically less than 130 mm. This arrangement avoids problems of positioning and collision between the upstream circuitry connected to the outlets in the use configuration of the valve on a dive tank.
