Abstract
In an electric motor-pump assembly, two working diaphragms, each delimiting a working chamber, are cyclically driven by a crank drive via connecting rods. The crank drive includes eccentrics for each connecting rod, which are placed on an axial bearing journal in the extension of an output shaft of an electric motor. In order to ensure a rotationally fixed connection between the eccentrics and the bearing journal to be produced and in order to ensure an angularly precise position of the two eccentrics, each of the eccentrics is connected to the bearing journal by a positively locking engagement.
