摘要： The invention relates to a motor-pump aggregate 101, particularly for providing pressure for a brake actuation device of a motor vehicle brake system having a pneumatic brake force amplifier, comprising a pump 102 and an electric motor 103 driving the pump 102, wherein the pump 102 is provided as a double-membrane pump having two opposing working membranes 104, each of which is clamped between a pump housing 105 and a working chamber cover 106, thereby bounding a working chamber 107, and which can be displaced by means of a crank drive 108 comprising an eccentric 109 and a connecting rod 110, the working chamber 107 being associated with one of each of an inlet channel 111 having an inlet valve 112, and an outlet valve 113 having an outlet valve 114. In order to provide a motor-pump aggregate comprising a dry-running pump and accommodating high standards with regard to acoustic comfort and service life, and being improved with regard to the pump efficiency thereof, the invention proposes that the outlet channels 113 be disposed in the working chamber covers 106 and in the pump housing 105 such that the air forced out of the working chambers 107 is guided into an inner chamber 128 of the pump housing 105 encompassing the crank drive, and that an air outlet unit 129 be provided that allows low-noise expulsion of the air from the inner chamber 128 by deflecting the air.
