<p>PURPOSE:To obtain a by-pass flow channel having a tube length sufficiently long for removing pulsations of excessive frequency, by buring a metallic by-pass tube having an inlet and an outlet each opened to a main flow channel in a tube wall so as to run in parallel with the main flow channel. CONSTITUTION:A main flow channel 2 is surrounded by a thickened tube wall made of a resilient material. An inlet main tube 19 and an outlet main tube 19' have an inlet and an outlet 4' opened therethrough respectively. One inlet 4 and one outlet 4' are connected therebetween by means of a by-pass tube channel 20 which is constituted in a predetermined shape such as a spiral by bending a copper or aan aluminum pipe, the by-pass tube channel 20 being integrated with these inlet and outlet by applying a brazing and the like. Other inlet 4 and other outlet 4' are likewise connected therebetween by means of other by-pass tube channel 20. In this manner, the inlet 4 and the outlet 4' are connected therebetween by means of a plurality of by-pass tube channels 20, and thereby forming a by-pass core.</p> |
