Abstract
A liquid filling apparatus comprises an apparatus body having a liquid channel connected at one end thereof to a liquid tank and at the other end thereof to a filling nozzle, a metering cylinder provided in the liquid channel between opposite ends thereof in communication with the ends for causing the liquid to be filled to flow into and out of the liquid channel by strokes of a piston housed in the cylinder, a check valve disposed upstream from the metering cylinder of the liquid channel, and valve opening-closing means for mechanically operating the check valve so as to open the valve during the inflow stroke of the piston and to close the valve during the outflow stroke of the piston.
