ABSTRACT:
The invention relates to a filling sluice for appliances for the treatment of infectious waste, with at least two chambers separable from on another via a rotary vane of stationary mounting and located in a sluice housing closable in a fluid-tight manner relative to the outside. For the rapid and reliable sluicing of infectious waste without a release of infectious germs, the rotary vane is arranged as a swingable partition wall between axially adjacent chambers and can be brought via an inflatable continuous sealing element to bear in a sealingly closing manner on the inner wall of the sluice housing.
