Abstract

Disclosed is a motor-pump assembly () for a brake actuating device of a motor vehicle brake system with a pneumatic brake booster. An electric motor () drives a double diaphragm pump () with two working diaphragms () which are located opposite one another. Air expelled from the working spaces () is directed into an interior space () surrounding a crank drive () of the pump housing (). An air outlet unit () permits low-noise expulsion of the air from the interior spaceby deflecting the air. In order to make available a low-noise, cost-reduced motor-pump assembly the eccentrics () each have an unbalance weight () integrally molded onto the eccentric ().
