Abstract (en)
[origin: EP0841483A2] The pump has a housing (G) with a groove (QN,FN) containing a sealing strip (DBS) to separate suction and pressure sides (SS,DS). The pivot point of the strip is positioned in the plane defined by the axis of the two toothed gears (Z1,2). There may be a turnable sealing strip on each end face of a gear. The movement of the strips is adjusted dependant upon the values measured by an RPM counter for the gears.
