Lubricating oil pump volume flow control, using a toothed ring pump for an IC motor, has a control disk between the pressure zone and the inner/outer cogwheels to set the flow according to motor running conditions

摘要

To control the pumped volume from a toothed ring pump (8), a control disk (3) sets the volume flow within the housing (1). The control disk is at least between a part of the outer zone of the inner cogwheel (5) and/or the outer cogwheel (4) and an inner zone of the pump housing. The control disk is also between the pump pressure zone (2.1) and the two inner and outer cogwheels.
