摘要： Delivery units are already known which have a drive rotor and an output rotor driven by the drive rotor, which are supported in a housing, interact in a meshing manner through a spur toothing in each case and draw fluid through at least one inlet and push said fluid out through an outlet, wherein the inlet and the outlet are separated from each other by two separating webs. In order to control the flow rate through the delivery unit, a rotational speed control, a bypass control, or, for gases, a suction throttling, for example, can be carried out. A rotational speed control is energy efficient, but very expensive, because an electric motor must be used, the rotational speed of which can be controlled. In the bypass control, the fluid is delivered from the outlet through a bypass back to the inlet, which however is energetically unfavorable and connected to hydraulic losses. The delivery unit according to the invention is improved in such a way that on the inlet side the flow rate can be controlled very easily and with few hydraulic losses and on the outlet side the inner compression can be adjusted in the event of delivery of gases. According to the invention, at least one of the separating webs (9,10) has at least one control opening (12), the opening cross-section of which can be controlled with a control slide (13).
