    • The invention relates to a motor-pump assembly 1, in particular for providing pressure for a brake actuating device of a motor vehicle brake system, having a pneumatic brake force booster, in particular a vacuum brake force booster, comprising a pump 2 and an electric motor 3 which drives the pump 2, wherein the pump 2 is provided as a double-diaphragm pump with two opposite working diaphragms 4, wherein outlet ducts 21 are provided so as to be arranged in working chamber covers 6 and in the pump housing 5 in such a way that air which is displaced out of working chambers 7 is conducted into an interior space 22, which surrounds a crank drive 8, of the pump housing 5, and that an air outlet unit 23, 53 is provided which enables the air to be blown out of the interior space 22 in a quiet fashion by deflecting the air, and wherein the air outlet unit 23, 53 comprises 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. To provide a quiet, reduced-cost motor-pump assembly which requires reduced assembly expenditure in comparison with the known generic unit, it is proposed according to the invention that an intermediate base 37, 55 is provided between the filter housing 32, 54 and the air outlet cover 34, 56, which intermediate base 37, 55 deflects the air emerging from the interior space 22 into the air outlet unit 23, 53, and that the valve holding element 38, 70 is integrally formed on the intermediate base 37, 55.
