Abstract
A tubular element (100) which is inserted into a liquid-conducting conduit (10) includes an annular chamber (25) that is delimited radially towards the inside by a tubing section (30) made of a material with an elastically flexible surface. The tubular element (100) serves as a flexible damping conduit section, or, if the annular chamber (25) is connected with a partial vacuum chamber at a connector (21), and the tubing section (30) is inflated into the annular chamber (25), as a means for temporarily holding an amount of liquid, for example in order to withdraw a dye bath from the exit slit of an application device for dyeing textile webs.
Claims6
A device for applying a fluid for applying a fluid processing agent to a web comprising:
- an application head for applying the fluid to the web;
- means for transporting the web past the application head;
- a feed line for supplying the fluid processing agent to the application head, the feed line having an inner diameter;
- a pressure accumulator arranged in the fluid feed line;
- the pressure accumulator comprising:
- a tubular housing the housing forming an annular chamber with an inner diameter, the inner diameter of the annular chamber being larger than the inner diameter of the feed line;
- an elastic sleeve, the diameter of the elastic sleeve being substantially the same as the inner diameter of the feed line, the elastic sleeve sealingly fastened to the housing to form a fluid passageway and separate the passageway from the annular chamber;
- a control valve in fluid communication with the annular chamber, a vacuum source and a pressure source, wherein the control valve selectively applies either a vacuum or pressure to the annular chamber.
