<p>Pulsations in a pressurized fluid flowing through a conduit pipe is prevented by changing the inner volume of the pipe by changing the cross-sectional area of a flexible pipe portion in dependence upon the pressure of the flowing fluid without changing the peripheral length of the cross-section of the pipe portion thereby absorbing any pressure changes. For this purpose the apparatus comprises a tube or a hollow substantially spherical body having flexibility in at least one cross-section thereof, and a member operating as an elastic body for resiliently regulating the cross-sectional area of the inner bore of the tube or the substantially spherical body to a cross-sectional area less than the maximum cross-sectional area thereof.</p> |
