Pharmacological liquid reservoir filler - has piston which is advanced by turning a rotary component linked to it by rack and pinion mechanism

摘要

The filler, designed to transfer a liquid to a reservoir from a main container, has a piston (101, 102) which is advanced by turning a rotary component which is connected to it by a rack (41, 42) and pinion (43) mechanism, with the pinion (43) disengaging from the rack at the end of the piston's travel.
