ABSTRACT:
A toilet, particularly adapted for handling liquid and solid bodily waste in a zero gravity environment, including a housing with a main wall having a central waste-receiving opening therein, and a plurality of toroidal elements in close stacked relationship in a coaxial array that extends inwardly of the housing from the central opening, and a flexible, resilient inner wall of each element being inwardly expandable and retractable, and air compression and suction means in flow communication with each element for pneumatically expanding and contracting the flexible wall of each element. A flexible bag has an open end that mounts about the central opening, an elongated neck portion that is embraced by the toroidal elements, and another portion for accumulating waste material. The bag is porous to gases and impervious to solids and liquids. Spray means can inject a water spray at the central opening, and housing exhaust means can cause airflow into the open end of the bag and out through its porous walls. Control means for the air pressure and vacuum sources cause the elements of the toroidal array to contract sequentially across the neck of the bag in an inwardly moving peristaltic-like wave.
