Gas flow control device for breathing apparatus for living beings

摘要

A gas flow conductor (2) for conducting a gas flow (G) is proposed, marked by a ring body (10),which is trained to guide the gas flow (G) and which extends along an axial axis (A) with a ring length (L) from a first ring end (11) to a second ring end (12), the ring body (10) at the first ring end (11) having a first pass opening (11a) and at the second ring end (12)has a second aperture (12a) between which a ring canal (13) is located within the ring body (10), with an inner cloak (14) of the ring head (10) limiting the ring canal (13) from the axis (A) in a radial direction (r) along the axis (A),and a control unit located within the ring canal (13) to control the gas flow through the ring body (10);where the control unit (20) comprises at least one first control element (21, 23), with at least one first control element (21, 23) along the axis (A) with a first control element length (L1, L1',L1'') extends from a first control element (21a) to a second control element (21b) in a radial direction (r) with a first control element height (H1, H1',H1') from a first base (F1) to a first base (S1, S1',S1'') and in the circumference direction (U) a first control element thickness (D1, D1',(D1') is available.
