Abstract

A pressure reducing system for a breathing apparatus may include a conduit and a mouthpiece. The system may also include a valve poppet operatively interposed between the conduit and the mouthpiece, the valve poppet being movable between a closed position and an open position. The conduit may include an abutment against which the valve poppet abuts in the closed position and from which the valve poppet is distanced in the open position, and the abutment may define an annular interface which in the closed position is in contact with the valve poppet. The system may also include a balancing chamber that defines a pressure balancing zone. The valve poppet may define a passage that places the conduit and the pressure balancing chamber in fluid communication and a section of said passage, in the open positions extends in the supply conduit beyond said annular interface.
