Abstract

An apparatus for delivering measured liquid volumes comprises a dosing piston pump (13) having an outlet (53/54) for the measured liquid volumes, and a liquid accumulating device (12) including an accumulator chamber (17) having an inlet for liquid to be dispensed. The accumulator chamber (17) communicates with the pump chamber (30) of the dosing piston pump through a transfer passage (31) having a valve (14) for controlling the transfer of liquid from the accumulator chamber to the pump chamber. The accumulator chamber (17) is expandable to accommodate constantly inflowing liquid through the inlet when the transfer passage (31) is blocked and is contractable as a result of the displacement of a movable wall member (18) so as when the transfer passage is open to transfer accumulated liquid to the dosing piston pump while inflowing liquid flows direct to the dosing piston pump.
