Abstract
An apparatus wherein liquid may be continuously fed at a constant small rate includes a liquid reservoir displaceable up and down and provided at a lower portion thereof with a liquid delivery orifice block, a small liquid dropping tank displaceably supported for up and down movement and provided with a liquid dropping chute and an intake nozzle communicating with the orifice block and disposed at a location lower than the location where the liquid dropping chute is attached to the small liquid dropping tank, a photoelectric droplet counting mechanism provided facing a dropping portion of the dropping chute, and a reservoir raising/lowering mechanism and a tank raising/lowering mechanism adapted respectively to either raise or lower the liquid reservoir and dropping tank in accordance with signals from the counting mechanism. The above apparatus is particularly suitable for feeding a rated amount of the liquid such that its viscosity increases considerably when a certain magnitude of compression and shear forces are applied.
