An infusion pump for the dosed administration of a liquid includes a liquid conveying device, for example a pressure spring permanently impinging a piston tappet with pressure, and a distribution control device, for example a stop valve, for dosing the liquid distribution. The liquid conveying device impinges the liquid at the inlet of the distribution control device with pressure and the liquid conveying means is decoupled from the distribution control device. Exactness of dosage thus depends on the work tolerances of the liquid conveying means and is substantially only controlled by the exactness of the distribution control device which can be suitably adjusted. The invention encompasses a control method, a control program and a micro-processor component, and is suitable for mobile infusion pump systems, for example in the long-term administration of micro-doses of insulin to diabetes patients.
