Abstract (en)
[origin: US5782617A] A capsule-type dosing pump wherein the minimum volume of the pump capsule is reduced substantially to zero through use of a stationary capsule wall which is shaped so as to complement, i.e., to conform to, the bulged-out shape of the capsule diaphragm when in its most forward position, and wherein means are provided for ensuring that the capsule diaphragm, when in its most forward position thereof, will lie flush against the complementary surface of the stationary capsule wall so as to prevent pockets of liquids from forming therebetween.
