ABSTRACT:
The present invention relates to a motor-pump unit for slip-controlled vehicle brake systems, including an accommodating member for hydraulically active elements comprising at least one working piston, which is arranged and guided in the accommodating member so as to be movable in a translational manner, and projects with an end into a crank space6for a rotationally movable driving element which is encompassed by a bearing having a bearing ring with an essentially bowl-shaped bottom, and extends over a frontal end of the driving element, and wherein the bottom is movable with an outside surface to rest against a crank space bottom.To improve friction and wear conditions, the crank space bottom includes an axial bearing element for the bottom which, starting from the accommodating member, projects in the direction of the bottom and has a contact surface with an area smaller than the area of the outside surface.
