<p>The dosing pump of plastic for the dosed dispensing of a paste-form medium has a pump component consisting of a spring elastic bellows installed between fixed cylindrical lower housing section and an axially movable upper housing section. A rotatable sleeve (30,30/1) is rotatably mounted in the lower housing section between the lower and upper housing sections and engages with the axially movable housing section via thread-like engagement elements which convert the rotational movements of the sleeve into axial lift movements of the upper housing section.</p> |
