[ What is claimed is:] [1.]1. Hydraulic delivery device with a displacement unit mounted in a housing and set in rotation through a drivable shaft unit and which comprises a rotor mounted rotationally secured on the shaft in a pump chamber, and with means which during rotation of the rotor produce at least a suction region with increasing volume and at least a pressure region with reducing volume, wherein the suction region is connected to a suction connection of the delivery device and the pressure region is connected to a pressure connection of the delivery device;wherein the pump chamber is defined by surfaces aligned radially relative to the shaft, wherein the pump chamber is defined on one side by a plate which produces a hydraulic control function of the delivery device, a sealing device for sealing regions of the delivery device which are under different pressures, and wherein the plate produces an axial positioning of the shaft after fitting and centering the plate;wherein the plate is mounted rotationally fixed and with one surface bears flat against a surface of a housing part;wherein a surface of the plate running parallel to the surface forms a running surface for the rotor;wherein the plate has a through bore through which the shaft is guided; andwherein the through bore has shaped features which after fitting the shaft, more particularly after centering the plate, form with a guide section of the shaft an axial stop for the shaft.
