Metering system

Abstract

The invention relates to a metering system () for metering a metered medium comprising a frame housing unit () and a lever mounting unit () which his supported on the frame housing unit () comprising a lever mount (). The invention further comprises a, preferably asymmetrical lever () which is supported rotatably by means of the lever mount () about a tilt axis (R) comprising a two-sided lever arm () extending substantially in a longitudinal direction (L) of the lever (), wherein one lever arm side (), preferably the longer lever arm side (), has a first actuator engagement point () close to the tilt axis and is in contact remotely from the tilt axis at an end portion () with an ejection element (), preferably a ram (), and wherein the other lever arm side (), preferably the shorter lever arm side (), has a second actuator engagement point () close to the tilt axis. The invention further comprises two actuators (), which, during operation, exert a tilting moment in opposite directions on the lever () at the first and second actuator engagement point (), wherein the actuators () are placed obliquely to one another. Together, the lever mounting unit (), the lever (), and the two actuators () thereby form a movement mechanism (), which is braced on the frame housing unit () by means of at least one spring element (), preferably a disc spring set (), wherein the spring element () is preferably arranged so that it braces the lever mounting unit () against the frame housing unit () via the lever () as well as via the two actuators ().
