Title of Invention

A LIQUID METERING DEVICE

Abstract The present invention relates to a liquid metering device. The liquid metering device comprises a housing having an inlet and an outlet for allowing flow of liquid, said housing made of cylinder accommodating a piston assembled on a connecting rod and performing a linear motion; a crank shaft having an eccentric portions performing a rotary motion and a roller/s incorporated on the eccentric portion of the crank shaft providing operational contact between the crank shaft and the connecting rod; and a stopper provided on the housing for each cylinder such that the stopper restricts the movement of the connecting rod before the connecting rod butts against the roller completing the stroke. This results in increase life of the liquid metering device and also delivers set value of the volume for a long duration.
