Abstract (en)
What shall be described is a demand-valve (1) for delivering air into a compressed-air breathing apparatus that comprises a substantially cylindrical chamber (3), a first entry-gate (14) for admitting air into the chamber, that presents a passage-opening - controlled by intercepting-means which comprise a blocking-element (20) that is mechanically connected to a deformable membrane (7), and a second entrygate (15) predisposed for feeding-in said air. The device is characterized by the fact that, the axis (a1) of said first entry-gate forms a first angle ( alpha ) with the bottom-surface (8) of said chamber, and that the axis (a2) of said second exit-gate forms a second angle ( beta ) with the lateral-surface (4) of the chamber; said two axes lying substantially on the same diametrical plane of said chamber.
