Abstract

A pump is provided which is capable of delivering measured doses of a liquid, the pump comprising a body having a longitudinal passage, and a pair of opposed pistons slidingly received in said longitudinal passage, cross passages in said body which communicate with the longitudinal passage and constitute respectively an inlet port and an outlet port, means for moving the pistons in unison between the inlet port and outlet port while their opposed faces are spaced by a distance defining the liquid dose and means for closing the gap between the pistons while the pistons are in the region of the outlet port so as to deliver a measured dose of liquid through the outlet.
