TUBE FOR A PINCH VALVE, PINCH VALVE AND POWDER GAS JET DEVICE HAVING SUCH A TUBE AND METHOD FOR PRODUCING SUCH A TUBE FOR A PINCH VALVE

摘要

A tube (10) for a pinch valve (1), in particular incorporated into a powder gas jet device (100), the tube (10) having an inner channel (11) for transporting a medium under pressure in an operation mode along a transport direction (T), the tube (10) having an inner curvature delineating the circumference of the inner channel (11) in a cross section of the tube (10) along a plane perpendicular to the inner channel (T), a shape of the tube (10) being configured such that the inner curvature (13) presents at least a contraction section, which, in the operation mode, undergoes deformation forces that tend to contract the contraction section of the inner curvature (13).
