Date Sep. 8, 1995A hollow body and a method for producing a hollow body having at least two oval sleeves and an annular connecting journal between each of the sleeves. Each of the sleeves has uniform circumferential wall thickness and an outer peripheral region having a smaller radius and forming a crown. The annular connecting journals have a uniform circumferential wall thickness, a circular inner surface and are disposed between each of the oval sleeves. Each oval sleeve projects over the annular connecting journal in the region of the smaller radius with the projection being greatest at the crown. The wall thickness of the annular connecting journal is partly greater than the wall thickness of the oval sleeve. The annular connecting journal and the oval sleeve have equal cross-sectional areas. Material remaining between the annular connecting journal and the oval sleeves after forming is removed from the small radius region of the oval sleeve.
