An adaptor assembly including an adapter body having a fluid passage extending therethrough with a poppet valve movable between open and closed positions. The poppet valve is supported on a valve stem having a gear rack thereon. A shaft extends into the adapter body and supports a manually movable handle exteriorly of the adapter body. A pinion engaging the gear rack is supported on the shaft through a lost motion connection so that the poppet valve may automatically open as the pinion rotates independently of the shaft yet may be opened as the pinion is rotated by the shaft.
