CONDUIT CLEANING APPARATUS

摘要

An apparatus (1) for controlling the flow of fluid in a conduit comprises a main body (2) including a bore, having a first open end (3) and a second end (5), a fluid inlet for coupling said first open end (3) of said main body to a source of fluid, a fluid outlet (19) adapted to direct at least a portion of the fluid entering via the fluid inlet in a direction so as to propel the apparatus through the interior of the conduit. The apparatus comprises a control element (15) movable between (a) a first position in which at least one fluid path exists between at least one said fluid inlet and at least one said first fluid outlet (19); and (b) a second position in which at least one fluid path exists between at least one said fluid inlet and at least one said second fluid outlet (17). The fluid paths formed comprise at least one curvilinear portion.
