Abstract
A vacuum toilet for use with a waste pipe maintained under partial vacuum pressure. The vacuum toilet comprises a bowl having an upper surface defining an opening and a lid supported for pivotable movement between a lowered position, in which the lid covers the opening, and a raised position, in which the lid is rotated away from the opening. An actuator has a rod connected to the lid, the rod being movable between a first position, in which the lid is placed in the raised position, and a second position, in which the lid is placed in the lowered position. A controller is operatively connected to the actuator, wherein the controller normally operates the actuator with the rod in the first position. The controller automatically operates the actuator rod to the second position during a toilet flush cycle, and subsequently returns the actuator rod back to the first position after the toilet flush cycle.
