Abstract (en)
[origin: EP0737812A1] The teeth of the gearwheels in their circulating direction in front of the plane contg. the gearwheel axes form a pressure zone communicating with a pressure conduit and a pressure nodule and in the circulating direction behind the plane a suction zone. This suction zone communicates with a suction conduit and with a suction nodule. In the circulating direction of the delivery gearwheels, behind the suction zone, is a feed zone which can be fed with excess pump medium from the gearwheel pump at excess pressure and increased flow speed. The suction nodule extending over the suction-side cross point (12) is connected with the feed zone (channel 7).
