<p>The fitting has a telescopic outflow conduit system with a throughflow tube (43) that is retained on a base unit and an outflow tube (45) that is longitudinally moved in relation to the throughflow tube, where one tube is an inner tube and the other tube is an outer tube. A resultant hydraulic force acting in a longitudinal direction is compensated for by frictional forces acting between the throughflow and outflow tubes.</p> |
