Abstract: A rotary pump, preferably a vacuum pump, featuring: a delivery space including an inlet on a low-pressure side and an outlet on a high-pressure side of the pump; a rotor which is arranged in the delivery space and delivers a fluid from the inlet into the delivery space to the outlet from the delivery space; at least one housing part which delineates the delivery space at least axially; and a drive shaft which is connected in drive terms to the rotor; including at least one sealing element which is connected, secured against shifting and/or rotating, to the drive shaft and/or rotor and forms a radial sealing gap with the housing part.

Abstract: A pump device for a motor vehicle, includes a pump device housing; a delivery chamber which is formed in the pump device housing and/or at least partially by the pump device housing and which includes an inlet and an outlet; a delivery structure which is arranged in the delivery chamber and delivers a fluid from the inlet on a low-pressure side of the pump device to the outlet on a high-pressure side of the pump device; a first conduit which channels the fluid from the outlet out of the delivery chamber to a first assembly; wherein a second conduit diverges from the first conduit in the region before the first assembly and feeds a portion of the pressurised fluid to a second assembly.
