An oil supply arrangement (1') for a burner feed device (2) is provided, having a pump (5') which has two main connections, namely, an intake connection (11) and an output connection (13') which is connected to the burner feed device (2). In arrangement of that kind, it is desirable to combine an improved efficiency with a high intake capacity. For that purpose, the pump (5') is in the form of a gear pump, the gear assembly (7, 8) of which in one rotation forms displacement chambers (10) that periodically increase and decrease in volume, at least one auxiliary connection (20, 22) being provided in the circulation direction between the main connections (11, 13'), the auxiliary connection (20, 22) being in fluid connection with the intermediate space between the components of the gear assembly (7, 8) and the main connection (11, 13') located downstream in the circulation direction. |
