Patent abstract
A metering device for producing a precisely metered volumetric flow is provided. The metering device comprises two displacement devices that are operated in phase opposition. In this case, the shifting speeds of the volumes of the displacement devices are adjusted such that no compensation flow takes place. In this state, the volumetric flow delivered to the device to be tested is identical to the volumetric flow taken in by the other displacement device from the pressure source.
