Abstract
Official abstract text for this publication.
A method for circuit separation testing in a double gearwheel pump having two gearwheel pumps includes charging one of the two gearwheel pumps with pressure and measuring the pressure build-up in the charged gearwheel pump and/or the pressure-build up in the other gearwheel pump. The pressure build-up is preferably realized by the gearwheel pump itself. The gearwheel pumps have a common pump shaft and are preferably configured as hydraulic pumps of a hydraulic vehicle brake system with slip control. The method detects any leak at the leadthrough of the pump shaft through a partition wall between the two gearwheel pumps.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method for circuit separation testing in a double gearwheel pump, comprising: closing a pump outlet of a first gearwheel pump of two gearwheel pumps arranged in a pump casing to build up pressure in the first gearwheel pump, the gearwheel pumps having a common pump shaft that passes rotatably and in a sealed manner through a partition wall arranged between the two gearwheel pumps; after the pressure buildup, closing a pump inlet of the first gearwh…
