Abstract (en)
[origin: WO2014016388A1] The present invention relates to a metering system for metering a fluid metered medium, with a suction line that is filled with a metered medium at fluid pressure ps, and a pressure line that is filled with the metered medium at fluid pressure pd, wherein the suction line is connected to the pressure line via a metering member constructed as a metering pump, with which metered medium can be conveyed from the suction line into the pressure line, wherein the metering pump has a delivery chamber, the volume of which can be varied with the assistance of a movable displacement element in such a manner that the delivery chamber has a minimum volume Vmin in a first position of the displacement element and a maximum volume Vmax in a second position of the displacement element, wherein the delivery chamber is connected via a pressure valve to the pressure line and via a suction valve to the suction line, such that, by means of an oscillating movement of the displacement element, metered medium can alternately be drawn out of the suction line via the suction valve into the delivery chamber and metered medium can be discharged from the delivery chamber via the pressure valve into the pressure line. In order to provide a metering system and a metering pump adapted thereto which has a high efficiency, no leakage flow and is easy to construct, according to the invention the formula (I) is provided where kappa = 1.5.
