Abstract

A liquid conveying device, especially for oil burners, with a gear pump that draws liquid from a lower reservoir and routes it to a consumer through a regulator that maintains constant pressure and is fitted with a return line characterized in that the gear pump has, in the area of its maximum chamber volume between the suction side and the pressure side, preferably in the plane of symmetry of the gear pump, a supply device that feeds the chambers with liquid under a loading pressure, which is substantially higher than atmospheric pressure, but still substantially lower than the operating pressure of the transport device.
