摘要

The siphon (U) has a variable-position discharge pipe. The unit has an enclosed housing (1) with an inlet (2) positioned over an outlet (3, 3'). The housing encloses a canal labyrinth which holds a liquid forming an odour barrier. During the in-flow of a large quantity of fluid, the barrier triggers suction discharge. The lower part of the housing (1) has esp. two apertures pointing in different directions. One of the apertures is presented to the discharge tube as selected. The other outlet serves as a maintenance/cleaning aperture in conjunction with the cap (5).
