Abstract:
1. A micro-dosing pump comprising: a pump chamber substrate having a pump chamber; a flexible membrane provided on a first side of the pump chamber substrate such that it covers the pump chamber in a fluid-tight manner; at least one fluid line provided on a second side of the pump chamber substrate such that a fluid can enter and leave the pump chamber; a rotatable valve disk having at least one fluid through-opening, the valve disk arranged inside the pump chamber and configured to close the fluid line by a rotation and to open it via the fluid through-opening; a permanently magnetized or magnetizable actuator disk coupled to the valve disk via at least one resiliently elastic element such that rotating the actuator disk rotates the valve disk, wherein the resiliently elastic element is configured to press the valve disk and the actuator disk away from each other; and a drive unit having a magnetic pump plunger configured to move the membrane for suction or ejection of the fluid and configured to rotate the permanently magnetized or magnetizable actuator disk.
