FIELD: diving technology.
SUBSTANCE: invention relates to diving equipment, devices of forced gas supply into a diving breathing apparatus. The oxygen supply valve of a diving breathing apparatus consists of a hollow rod with holes and a base with an insert made of soft material ensuring its tight fit to the valve seat located in the pipeline. A core and spring are mounted on the top of the valve base. When the valve is in the closed state, through a nozzle integrated into the hollow rod, there is a constant supply of oxygen into the breathing circuit of the diving breathing apparatus, and if it is necessary to increase the flow of oxygen, the valve is retracted from the seat to a fixed tip with a shock-absorbing seal by the electromagnetic field generated by the solenoid coil.
EFFECT: reduction in energy consumption and an increase in the service life of normally closed electromagnetic valves used in diving breathing apparatus.
