Abstract
A vacuum toilet system is protected against overflow of a toilet bowl by an overflow protection system that automatically generates an overflow condition signal when the toilet bowl is in a near-full condition and initiates a discharge valve operating cycle, in which the discharge valve of the toilet bowl is opened and closed independently of the flush member associated with the toilet bowl, in response to the overflow condition signal.
