ABSTRACT:
There is disclosed a metering device having a mechanism for incrementally moving a piston rod in one direction only, until a reset mechanism is actuated to automatically return the piston rod to its initial position. A one-way locking device prevents the piston rod from returning before the reset mechanism is actuated. The device is constructed to meter liquid from a container supported relative to the piston rod.
