Abstract

A motor/pump assembly for a motor vehicle brake system including a pump and a motor driving the pump, the pump having opposite working diaphragms which are, in each case, mounted between a pump casing and a cover and thereby delimit a space and which can be moved by a crank drive, the space being assigned, in each case, an inlet duct with an inlet valve and an outlet duct with an outlet valve. The outlet ducts are arranged in the covers and in the pump casing such that air displaced out of the spaces is conducted into an inner space surrounding the crank drive of the pump casing and that an air outlet unit be provided, which allows a low-noise blow-out of the air from the inner space as a result of the deflection of the air.
