Training equipment for respiratory function and control procedure for the supply of fresh air.

摘要

Training device for the respiratory function comprising a nozzle (3), a respiratory air channel (2), which follows the nozzle (3), with an inlet / outlet (4) for the air, a bag flexible air (2), which it is connected to the respiratory air channel (5), and a valve arrangement (6) for regulating the amount of stale air leaves the respiratory air channel (2) and the amount of fresh air entering said channel (2), characterized in that the valve arrangement comprises at least one piston valve (6), wherein the piston valve (6) has a housing (22) with a space air passage (26) and a sealing surface (27) disposed on the shirt of this space air passage (26), a valve body (23) being disposed in the space air passage (26) box (22) and being this valve body (23) slidably guided in the air passage space (26) and pudiendolo Desplà czar freely elespacio air passage (26) in the direction of the flow axis (28) of air from a sealing position to a position where at least a partial section of space air passage (26) is open, this valve body (23) having a plunger (24) with an outside sealing and guide element (25) for guided sliding in the space air passage (26) is acting the sealing area of ​​the piston (24) in the sealing position of the valve body (23) together with the sealing surface (27) into the jacket space of the air passage (26), closing the cross section of the passage space air (26) and arranged force generating means (29) for positioning the valve body (23) in this sealing position.
