摘要

Respiratory training apparatus comprises an outer casing with a (2) respiratory duct that is removably coupled to the (1), the mouthpiece (3), bladder (5), control devices (14). The valve device (2) in addition the piston valve is integrated into the respiratory duct. The piston valve includes a valve body, the valve element is freely movable, is not fixedly connected respiratory duct (2). The casing of the valve device or / and the casing part (1), means for generating a force is provided to hold the sealing position of the valve body, the means to determine the required opening force of the valve.
