Abstract

The invention relates to a reduction valve for respiratory apparatus in particular, which reduction valve is actuated by means of subatmospheric pressure and has at least one actuating leaf spring (1) in a bag (2) made of an elastic material. One end of the leaf spring (1) is fastened to the valve gate (5) and its other end (3) is fastened to a holder (6). The holder is fixedly connected to the valve face (7), the bag (2) being connected to the valve base (7) in a gastight manner and the inner volume (8) of the said bag (2) is connected to the reduced-pressure outlet (9). <IMAGE>
