Abstract (en)

[origin: DE4217259A1] The invention relates to a double pump consisting of a radial piston pump (1) and a vane-cell pump (2). The double pump is to be simplified in such a way that its overall length is reduced and there is only one casing separation. The radial piston pump (1) has a ring insert (8) fitted in an aperture (5) in the casing (4) with a moulded face plate to seal a pump set (20, 21, 22) of the vane-cell pump (2). One frontal surface (23) of the face plate belonging to the ring insert (8) together with the casing (1) also forms a dividing seam between the two pumps (1 and 2). Only one annular seal (35) is needed to seal the dividing seam. The ring insert (8) with a concentric drilling (36) also serves as a shaft (6) bearing and an axial stop face (38) in the region of the eccentric (12).
