Abstract

Disclosed is a motor-pump assembly (1) for a brake actuating device of a motor vehicle brake system with a pneumatic brake booster. An electric motor (3) drives a double diaphragm pump (2) with two working diaphragms (4) which are located opposite one another. Air expelled from the working spaces (7) is directed into an interior space (22) surrounding a crank drive (8) of the pump housing (5). An air outlet unit (13) permits low-noise expulsion of the air from the interior space 22 by deflecting the air.In order to make available a low-noise, cost-reduced motor-pump assembly the eccentrics (9) each have an unbalance weight (25) integrally molded onto the eccentric (9).
