Abstract
The invention relates to a pump assembly for a hydraulic brake system with traction control, having an electric motor and a piston pump. To reduce a bearing load, the invention proposes rotatably supporting and thereby radially bracing a motor shaft, or an eccentric sleeve pressed onto the motor shaft, on both sides of pump pistons. To economize on installation space, a pump bearing is disposed in an end of the eccentric sleeve that protrudes past the motor shaft.
