Abstract
In order to be able to exactly meter out even very small amounts, at least the outlet valve of the metering device—usually a piston metering device—is designed as a plug valve, having an axially displaceable or rotatable valve body. The inlet valve can likewise be a plug valve or also a diaphragm valve. The design comprising a displaceable valve body is preferred.
