Device for shutting off and/or control and/or regulating of air flow in pipe has elastically deformable pipe section located in pressure chamber charged with operating pressure acting upon pipe section

摘要

The device (01) for the shutting off and/or control and/or regulating of an air flow (02) in a pipe (03) has an operating component to change the resistance in the pipe. The operating component is an elastically deformable pipe section (04) which is integrated pressure tight in the pipe, whereby this section is located in a pressure chamber (06) which is charged with an operating pressure acting upon the pipe section. An adjusting component to change the operating pressure in the pressure chamber is provided between the pressure connection (08) of the device and a compressed air source.
