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 (23, 53) has a filter housing (32, 54), a filter (33, 59), an air outlet cover (34, 56), a valve holding element (38, 70) and a valve body (31). A partition wall (37, 55) deflects the air emerging from the interior space (22) in the air outlet unit (23, 53 between the filter housing (32, 54) and the air outlet cover (34, 56), with an integrally molded valve holding element (38, 70).
