Abstract
The housing of a vane-type machine has a largely cylindrical space for accommodating the vane cells. A shaft is eccentrically arranged in the housing. First and second guide plates are provided on the shaft. Slides displaceable largely radially to the shaft in the direction of the inner housing wall are guided by the guide plates. A vane cell is formed with the participation of two adjacent slides of the adjacent region of the inner housing wall and the volume of the vane cells in the region of an inlet opening differs from the volume of the vane cells in the region of an outlet opening. To increase the speed of the shaft and the temperature of the medium, the slides are lubricated by pressure oil and radially and axially guided by a guideway, which is fixed with respect to the housing.
