摘要

The device (10) has a feed pipe (20, 22, 24) with a section (46), which is guided to an intermediate container (48), where the section has an outlet aperture (88) arranged at a base of the intermediate container above an outlet (90) of the intermediate container. The feed pipe has another section (50), which is attached to the outlet aperture, and the intermediate container is provided with a ventilating valve (80) at its upper end. A leakage pipe re-circulates the washing liquid, which leaks from the valve, to a collecting container (84), and starts from the valve.
