摘要： A mechanical drive system for providing a maximum limit on the magnitude of unidirectional output motion in response to reciprocating input motion, including: an output member moveable in a first direction; a unidirectional drive for driving said output member in said first direction; limiter chain for limiting the motion of the unidirectional drive in the first direction to define a limit position; and an override drive mechanism responsive to the reciprocating input motion occurring in one direction to move the unidirectional drive to a rest position and to the reciprocating input motion occurring in the opposite direction to move the unidirectional drive in the first direction from the rest position no further than the limit position, irrespective of the extent of the reciprocating input motion to the override drive mechanism; and a periodically actuated fluid dispenser unit utilizing such a drive mechanism.
