Abstract

A dosing pump, in particular a microdosing pump, has a pump chamber in which a fluid inlet is provided at a first valve seat and a fluid outlet is provided at a second valve seat. A control element is coupled to an actuator to move the control element in order to vary the pump chamber in terms of volume. The control element is movably mounted by means of a flexure hinge.
