Abstract

A liquid charging and discharge cycle control mechanism in the form of a cistern water wastage control mechanism (10) comprises a displaceably mounted flow control member in the form of a conventional cistern water supply regulation piston (12) forming part of a piston and cylinder assembly (16) buoyancy providing means as provided by a buoyancy sphere (18) that interacts ball cock fashion with the piston (12) and a releasable locking device in the form of a spring biased finger-like formation (22) that is releasably engageable with a element receiving location in the form of a bore (24) into the piston (12). Except when a cistern fitted with the mechanism (10) is triggered to perform a flushing action the formation (22) locks the mechanism (10) against a continuous upstream refilling action in the case of cistern leakage.
